How to image the International Space Station (ISS) with planetary camera - part 2

In action - composite photo of the ISS pass

More and more people (gladly) are showing a growing interest toward ISS these days, probably because information about the overhead passes, transits are more accessible than ever before. And let's be honest, who wouldn't be interested in a spacecraft that us humans built, travelling 27,800 km/h, orbiting Earth at 400 km altitude 16 times a day.

When I first bought a scope for myself and became aware that there is this thing called ISS, I immediately thought to try to take an image of it. Than I've seen some of the best ISS photos on the web and I was immediately hooked. I wanted to do the same :)

The only way this could be done for beginners is manually moving the scope and hoping to capture a few useful frames.

Before you do anything outdoors, check what's happening, find details to know what you're dealing with (brightness, elevation, duration, etc.).
I normally get a pretty good summary of information from Here is a screenshot from the website about the ISS pass I've recorded.

Screesnshot from

The only way you can achieve it is this:

First and probably most important step is to align my reddot finder/Telrad/finder (whichever you have) scope dead accurate with my main scope. It means wherever I'm pointing my Telrad, my main scope will have the same object centered in the eyepiece/camera/dslr. This is very very important, because due relatively high magnification a small error will result in not having ISS in your camera's field of view at all. Therefore all goes to bin....
I made this mistake a few times and was frustrated a lot :) But hey, mistakes are to learn from them right!

Once finder is aligned to scope, the second important thing is camera settings.
I can't give you any exact advises on that, every planetary camera/dslr has it's own sensitivity, therefore you have to find it out for yourself. Yes it means experimenting with your equipment. What I can give you is my experience at a given equipment.

Two ways of doing imaging. let's assume we are setting up for a very bright (between mag -2.5 and mag -3.5)
     - Using a dslr camera. Depending on the dslr you're using, you can record video or take raw/jpeg photos on continuous mode. Usually for photos the settings I've used at very bright passes was shutter at 1/1250 and ISO at either 800 or 1600 (equipment 90/1250 maksutov + Canon 600D)

     - Using a planetary camera. I personally use a Zwo ASI 120MC, settings usually and the settings on this particular attempt at mag -3.0 was: Shutter 0.800 and Gain 60 ( equipment 127/1500 maksutov + Zwo ASI 120MC color camera).
(Update: My color camera is gone, instead I'll use a 120MM mono version from now on. The first shots are at the bottom of the post, taken through hazy sky.)

The rest of the job is determination, enthusiasm and a never giving up attitude :)

I used to use an equatorial mount for manually tracking ISS, but my experience is not the best with it. An Alt-Az mount or a dobsonian type scope is probably the best for this purpose.

Here is a video about how imaging works for me. Time lapse of 10s expos about the preparations and the pass itself.


Sometimes I've got comments like "nice CGI" or "green screen, fake" etc. Well I can not document the event better than this, if someone chooses not to accept that Earth is a globe (not flat) and things actually orbiting around it, I can't really argue any longer....

Have one of these apps:

     - ISS Detector (android)
     - Sputnik (iOS)

These two images below were taken with a Skywatcher 250/1200 Flextube scope on a dobson platform, that seems to have advantages by its built to follow ISS much easier, than doing the same with an equatorial of alt-az platform. Also a Zwo ASI 120MM mono camera was used to capture frames.

Taken with my new ASI 120MM monochrome camera

Japanese HTV-6 docked and a month later gone

The blog post will hopefully give you a good idea, how this is exactly done. It works for me and hope you might find it useful.

Good luck!!

Best way to get good information about the overhead passes

ISS solar transit - twice in a week

One of the rear occasions, when ISS was crossing the disk of Sun twice in a week time and twice at near perfectly clear sky. From London! :)

For the first one it happened on the 17th of August -  I had to drive up near M1 motorway. I did not have a scope with me sadly, I was working and just took a short break. Luckily I had my Canon 600D and a 75-300mm lens with me. At highest magnification, white light filter, this was the final result.

The second one ( 21st of August) was near Slough, sky was cloudy when I left home, but because ISS was only in a distance of 517 km, I decided to go whatever happens. You need to be in it to win it right :D
So packed up and hit the road. At my arrival to a randomly chosen location along the centerline clouds began to brake up and it was more a lightly scattered cloudy sky.


There was a patch of cloud 2 mins before the transit, but already saw that this might be really good to me as clouds were moving rapidly out of the way and clear spell was following afterwards. About half a minute before the transit it was bright and clear. Capture began and whooops there it was. A quick 0.68s transit.

Happy happy happy times.

Of course the last minute setting adjustment wasn't ideal, I should have had lower gain and higher shutter speed, the final result was a bit noisy. But it all does not matter. Every time I try to learn from my mistakes and let's not forget, an hour and a half before the transit, it all looked doom and gloom, so no room for complaining whatsoever...

Solar arrays are nicely visible

Here is a video about the whole project, the original and half speed transit video, screenshots of the predicted transit using CalSky.

Mars challenge 2016

Sometime in December 2015 I took a photo through my 200/1000 newton tube, when Mars was still far far away (248 million km away - angular diameter  4.9 arcsec) and it looked like a tiny reddish ball without any surface details.
Then in January I did the same project, only slightly but it was definitely bigger, still a whopping  241 million km away - angular diameter  5.8 arcsec.

Then the idea came, what if I am going to take a shot of the red planet whenever the weather allows me - to capture as it get closer and closer to Earth till it reaches it's closest. Looking back now, weather was crucial part of the project, I had to have a good few weeks of brake due extremely bad weather over UK.

In the meantime I changed equipment, decided to use my beloved 127/1500 maksutov tube with a Zwo ASI 120 MC color planetary camera and a TeleVue 2.5x powermate. Now I had 3750mm of focal length to deal with and it proved pretty useful for this purpose. The planetary camera's region of interest (ROI) was always the same 480x320, this is how I could guarantee the foundation of the proper comparison. 

So the real project started on the 18th of April (2016), Mars was "only" 94 million km away from us and it's angular diameter at 14.2", more than double compare to January. Already showed quite some surface details - I was recommended to use WinJupos to find out what Mars is showing to me at a given time. It worked perfectly and later on, when the red planet was very close I could even identify certain features like Syrtis Major Planum or Olympus Mons. 

Because I used two different tubes at the beginning, eventually I dumped the ones taken with the newton to avoid any confusions. But on this photo the size of the planets are roughly fine, adjusted by basic measurements. 

The shots were taken absolutely randomly as weather was still very unpredictable. But still could manage to take a shot with no bigger gaps then two weeks. Mars just grew and grew all the way to a diameter of 18.6" at its biggest on the 27th of May. 

Clear weather was just one thing, seeing, humidity and jet stream made me run for my money :) I had to wait till the 5th of June for the best of the season. I had the privilege to use my scope and give a try to a Celestron C9.25 SCT too. Here is the result....

Performance comparison of a Skywatcher 127 maksutov and a Celestron C9.25.
WinJupos screenshot in the middle 

From that night here is a link to a gif I have made - gives a bit of a clue what would it feels like seeing any planet over the time as they rotate around their axis...

My plan was to keep doing it as long as possible. Visually Mars looked still very pleasing, definitely to the naked eye, less promising through a scope. So I had to came to the realization that the project is over now. Especially from the UK - even at its highest it was only 16° above horizon - far from ideal. 

Having said that I am very pleased for the result, didn't even dream of having details on a scale like this. This is the final version so far, I might modify it somewhat in the future though :)

Tiangong-1 (Heavenly Palace) - Chinese Space Station

Tiangong-1 (Wikipedia)

Tiangong-1 (literally: "Heavenly Palace 1") is China's first space station, serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities. Launched unmanned aboard a Long March 2F/G rocket on 29 September 2011, it is the first operational component of the Tiangong program, which aims to place a larger, modular station into orbit by 2023. As of September 2011, Tiangong-1 was projected to be deorbited in 2013 and replaced over the following decade by the larger Tiangong-2 and Tiangong-3 modules. However, Tiangong-1 remains in orbit as of 2016. (source "Wikipedia")

In my entire life I have seen this very space station 
only three times. Once in January during my visit to Gran Canaria. Unfortunately I didn't have my imaging equipment with me on that morning, so I saw it only visually. Sadly that was the end of the visible passes from that location....
Few days ago I realized Tiangong-1 will be visible from UK for a few days, will be at it's brightest on the 1st and 2nd of July. From my two attempts the first was a success, second a total failure...

I have used website this time to find out the when, where from and the brightness details.
The screenshot on the left gave me the basic reference points. My idea was to somehow capture it close to Mars, most ideal case transiting Mars (on the 2nd of July). But the experience I have gained during the 1st of July attempt made me change plans.

The Chinese Space Station is a difficult target after all. It only came as high as 16 degrees above the horizon, which means by the time I could image it due tree obstruction in front of my balcony, the distance between me and the station was around 1100-1250 km. The ISS would look smaller too at this distance, so being aware of this I used a radical equipment - SW 127 mak + TeleVue 2.5x powermate + ASI 120MC. This was a powerful setup, giving me a whopping 3750 mm of focal lenght.

That could have been pretty promising, but difficulties did not end here. Based on my experience on planetary imaging I was aware, the powermate will limit me a lot as it allows less amount of light to hit my camera's sensor than without. Adding this to the fact, that Tiangong brightened up only at a value of mag +3.0 which is very very faint
to ISS ( good overhead passes are between mag -1.0 and mag -3.9).

My photo of Tiangong-1

I remember watcing back the footage I shot was an unpleasant feeling, because the station acted like a bright chewing gum on my screen. The problem lied in the settings, I guess video settings were quite underexposed.  I did not have much faith, nearly deleted the footage straight away.

Luckily I didn't :)

After going through every single frame - I have found ONE single frame which showed me something only in my wildest dreams I dreamt of. I know it might be slightly squashed - mainly due poor seeing (wild jet stream at the moment) and the vast distance, especially the solar panels look squashes a bit.

But hey, it's definitely there, the main body structure with the two solar panels on the sides.

Already much much more that I have previously expected :P

International Space Station transiting our Sun

I have been planning this for some time now, but somehow did not have any luck with Sun and ISS these days. Today the predicted transit was about to happen at 12:35:28 from Wimbledon, United Kingdom.


The weather was splendid till about noon, when suddenly clouds began roll in, luckily scattered ones so looked like a good 50-50% success-fail ratio. Well just about 20 seconds after the transit, thin clouds obscured the Sun, but I was already very very happy by then :)

Prediction and details

I have used ISS Transit Prediction app, but wasn't 100% accurate (again), it gives an amazing estimate but to be fully sure about the exact path through the disk of Sun, I would recommend to use CalSky. Here is what the website said:

Centerline for the transit

CalSky shows the actual sunspots too, which helps to identify where ISS will enter and exit the disk of Sun


The usual Skywatcher 127/1500 maksutov was my main tool to capture the transit of ISS (with a Zwo ASI 120 MC color camera), but for the second time the 0.5x focal reducer was a huge help, I could squeeze a 50-60% the disk of Sun in my FOV. The only mistake I made is that I didn't check CalSky, only the ISS Transit Prediction app and the expected path through Sun was slightly off from my expectations. 

According to the app and my basic calculations, ISS should have gone through sunspot region 2536 and 2535, but ISS entered the disk above 2536 so missed a few frames sadly.
Conclusion: Always check CalSky.....

Final result

Mars rotation - Saturn moon hunt


Living in London, but in general being on the northern hemisphere drives amateur astronomers to the obvious conclusion, that Mars and Saturn are way out of our reach, at least from a photographer's point of view., Mars crawls only 16°  above the horizon.  It is going to be like this for a while, so I stopped getting angry about it and decided to make the most of it.

Mars rotation

Early wake up today, weather report predicted clear sky over London, seeing wasn't the best but hey, who has any expectations in this town?? :)
So set the alarm for 2am, after 3 hours of sleeping I did my usual quick setup on my balcony.

Had to wait a little for Mars till I had a clear view on it. Focused on the Moon and started shooting. my first video was taken at 2:40am and the last at 3:31am.

I used my beloved Skywatcher 127/1500 maksutov tube, a TeleVue 2.5x Powermate with my ASI 120MC colour camera with settings like this:
- gain 65
- shutter 7.830

It amazed me how much this red planet rotated just under one hour duration.


Mars and Saturn played hide and seek with the trees in front of me. When one was visible, the other one was obscured by the trees and the other way around. So at least I had time to spend on both without being rushed.

This was the original video I shot.....

This normally does not look promising, but I tried to get the best out of it using Autostakkert 2, Registax 6 and Photoshop. Saturn is at magnitude +0.2, so I had struggled with it compared to Mars (magnitude -1.3). It means that longer videos required for the same amount of frames as frame rate is lower due less amount of light hitting the sensor of the camera.

After processing this is my best, I could dig out some useful details.....

Also took a long video with more sensitive settings. It was quite challenging to capture any of them. The visual magnitude of the two moons were +9.0 (Titan) and +10.2 (Rhea).

And eventually these are all my Saturn shots I've ever took since I do astronomy. In a few years time this will be one of my best photos, if I can keep on taking shots every year...

Photo from WinJupos - as it looked on the 19th April
Mercury is the smallest planet in the Solar System and the one closest to the Sun, with an orbital period of about 88 Earth days, which is much faster than any other planet in the Solar System. Seen from Earth, it appears to move around its orbit in about 116 days. It has no known natural satellites. It is named after the Roman deity Mercurythe messenger to the gods.

On the 19th of April we had exceptionally great clear weather in London, no clouds and the atmosphere was calm. Because Mercury was nearly the farthest it can be from the Sun, it seemed like the perfect opportunity to take an image of it. 

I must admit, that my 127/1500 maksutov tube isn't probably the most suitable instrument for the job, but ever since I bought it keep surprising me with it's performance. Once again it happened.

Waiting for Mercury - equipment ready

Sunset was at 8:06pm, but a good 40 mins went past till I finally could spot it. Mercury's visual magnitude was only +0.4. The equipment was long ready for shooting, managed to get sharpness and the proper alignment of the main scope/red dot finder on Jupiter.
The photo at the beginning of this post is from WinJupos, a free software that can show current phases and the actual precise look of any solid body (does not work on gaseous planets as their surface change all the time). 

So I was looking for a crescent shape when I was looking for Mercury on the laptop screen. When I first found it, is was a big relief. Didn't really know what to expect... I must admit visually is wasn't the greatest, due it's low position on the sky made it look distorted and color dispersion was present as well, the blue and red was on the top and bottom separately.

I took a few videos, but knew time wasn't on my side as Mercury kept sinking lower and lower.
The first process of my video gave my this result.

The color does not match, but I'm not surprised at all. By the time I took my first video (at 20:48), Mercury was only 10° above horizon. Mainly this must be the reason, why not many of the amateur astronomers taking photos of it, very low and very small, not a good pain for sure.

My best image processing result is this one, saturation is set to nearly zero. I did a few reprocessing, did all the videos I've captured just to compare them. Reason is that black line close to north pole. First I assumed to be a stacking error, but after reprocessing all the other videos they show it too. So I only guess that must be surface detail, which still hard to believe with this size scope.

What a difference 3 days make around Plato crater?

Well we all know, that our closest celestial neighbour has phases and it constantly changing as it revolves around planet Earth. The illumination of it's surface shown to us increases and decreases day by day, but the way to actually see how dramatic this change is if we take a photo of the same area with a few days difference.

The photo below is a composite of two shots, one was taken on the 16th April and the other on the 19th April.
They show roughly the same area - Mare Imbrium mainly. The dominant crater on this two photos is Plato, between Mare Imbrium and Mare Frigoris, left form Montes Alpes.
But Aristoteles, Eudoxus, Archimedes and Aristillus craters are also quite exquisite features.

See how surface details "fade away" as Sun gets higher in the sky (if you were on Moon). Because no shadow present, the whole surface becomes pretty pale and harder to make up fine details.
Most likely that's the reason, why terminator (the dividing line between lit and unlit areas) is the most interesting target for observers. It you slowly move your scope alongside it, fantastic surface details can be observed, such as craters, mountains, valleys, seas etc.

ISS transiting the Moon - experiment on reducer

Hunting for ISS is a tiring task, needs lots of passion and enthusiasm for sure.
I still did not forget the disappointment of two missed transit on Jupiter within the last week or two but I don't give up that easy. I realized that the app that predicts transits (called ISS Transit Prediction for android only) can be set to alarm you about the coming up event.

Well yesterday 25 mins before the pass my alarm went on. Sky was clear so did a very very quick setup and 5 mins before the pass I was all ready to capture the moment. 


Skywatcher 127/1500 maksutov scope on an eq5 mount. Teamed up with a Zwo ASI 120 MC colour camera, but if I only insert the camera, it will give me a very small 
field of view (FOV) - no surprise, that's what planetary cameras are 
designed for.
I used exactly this setup yesterday
So lately I spent a little amount of money on a no name 0.5x focal reducer to roughly half the focal length of my scope. 

It gave me a pretty good FOV and I don't need to sacrifice the
resolution or the clarity of the photo. This proved to be an excellent
setup for this purpose, planning to use it fot the Mercury transit as well.


I use ISS Transit prediction app (only for android), but if I really want good accurate info, I visit CalSky website. They showed me the following information:

Proper description of the transit

Transit path on the map - zoomable on the website

This photo shows where ISS will appear relative to Moon's surface


My ASI camera definitely does not like daylight, every time I had to deal with imaging in daytime it is just a bit of a pain. But in Fire Capture you can change the amount blue colour (Wblue) - otherwise the whole Moon will be just blue. But that little option helped to find a right(ish ) colour balance.

Main parameters:Gain                        18
Shutter                     0.747ms

Histogram               29%
ROI                         1280x960
FPS (average) =       26

Only strange thing I've noticed is that most likely my laptop memory couldn't keep up with the data flow, so it kept missing frames. It happened to me before, but not on a scale like this. You can see the photo below, I could even squeeze my name in the gap, at least a good 3-4 frames were dropped. Also it occurred one more time, when ISS was at the Mare Nectaris/Mare Fecunditatis area. But it is what it is, I personally can't do anything with it, only a laptop/camera update will help. Not a major issue at the moment :)

ISS once again - lower trajectory

Every time when ISS appears on a lower trajectory - this was 47 degrees I believe - we have a unique way to see it. Instead of standing under it, we see it from a side angle too.

I used a my 127/1500 mak to capture this video.

I just love as it turns over and giving us a great view :) I had to watch it a few time to figure out, which way it is facing and turning toward. 

Also my favorite is part of the time lapse video, when something suddenly brightens up. I recon it must be the solar arrays on the docked cargo vehicles - as we have a few park to ISS (Dragon, Cygnus, Progress). This was the very first time I recorded anything like this :)

International Space Station (ISS) followed by Dragon spacecraft (CRS-8)

The history in space exploration is being written everyday, two days ago another success was achieved. Most likely everyone meet the news here or there, SpaceX successfully landed the first stage of the Falcon rocket onto a floating platform. 

We rarely see from London, if a cargo ship begins its hot pursuit to catch up with ISS. Well not this time ;)
I do image ISS from time to time, first I used a SW 200/1000 newtonian scope with a Canon 600D, then a SW Skymax 90/1250 maksutov and now a 127 maksutov teamed up with a Zwo ASI 120MC planetary camera. It is giving me a bit of a hard time as I struggle to find good settings with an ASI camera.

Setup is ready, wonderful sunset at the background
Anyway I went to a nearby open park to gain some more experience on how to capture ISS, every attempt gives me further reference points, what gain and shutter I should use. I knew Dragon might be visible, but probably only for the camera lens, not to my eyes.

So did my setup, waited for ISS to appear and began shooting my video. Below here is my best shot if the station, panels are reflecting a little amount of light, mainly the truss, the coolers, Columbus and Kibo labs, Zvezda, Zarya and Unity and Destiny parts are visible. 

International Space Station (ISS)

I kept my 600D clicking (with a Samyang 8mm fisheye lens on it) whilst I was busy with the ISS close up. I knew (from website) that Dragon will follow ISS within about a minute gap behind. But honestly I did not expect it to get as bright as it was.

ISS, Drgaon, Jupiter and Moon

So I stopped recording ISS, quicky set gain higher and started pointing my scope toward the Dragon spacecraft. I didn't know what to expect, I've never attempted to image such a small object travelling quite quickly. Here are the best two frames, One looks spherical (on the left) - similar to the front end of the cargo ship. But still pretty unsure what part of it is illuminated, sadly the solar panels remained hidden. I was hoping that at least those will be illuminated, which could make the identification a lot easier for sure.
