|Photo from WinJupos - as it looked on the 19th April|
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|
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.
