More random shots:
I don't know, looks more like Chromatic aberration to me...Well ...this is a very amateur picture, but it is the very first time I managed to photograph anything other than the moon. It was taken with an older model Canon Powershot, at 48 x zoom (12 x optical, the rest digital), And , from that picture, I had to zoom in and crop it just to see those few pixels . It looks like crap, but I still couldn't believe my eyes that I managed to see details. That's Mars, right there. You can even see the polar caps (sort of :lol: )
Bingo. For future reference you can upload any image of the stars here to have it automatically solved and its position determined. You don't even need to give it any information about the general location or field of view (though in some tough cases that can help speed up the solution).Pleiades, nice picture btw.
Unfortunately I didn't acquire images with the AO off during the first night's testing, I just wanted to maximize the time I had with it on. I do have an older image of M51 for comparison, but it's not apples-to-apples. The observing site was the same, and the total integration time was similar, but before the AO unit I took every shot with a .63 focal reducer; shooting at the full focal length of my telescope simply wasn't practical even with autoguiding. The latency and backlash of the drive system of the LX200 makes it virtually impossible to accurately autoguide fast enough at f/10. The AO unit has a response time of a fraction of a second and the very fast guiding rates make it possible to image at the full 2 meter focal length without a focal reducer. I took my older non-AO image of M51 and used bicubic sampling to resample it to the same size as my new higher resolution image of M51. Here's a gif overlay:Fascinating, Messierhunter. Is it possible for you to post a comparison with/without the adaptive optics?
All your works are truly great! During my sleep last night, a voice told me the following:First light test of an AO-7 adaptive optics system for my camera and telescope; it tracked like a champ with 5 minute exposures at the native 2000 mm focal length of my scope, which is quite difficult to do with an LX200 classic fork mount.
Man and Venus
Taken by Vladimir Scheglov on March 31, 2017 @ Magadan, Russia
After several attempts we were able to shoot my friend Alexander Korolenko during the rise of Venus. The distance between us was about 3300 m. Shot in the area of the Armanskiy pass, near Magadan. Thanks to Sergey Shibetskiy for the transport.
