Olyflyer, I use Spotting Scope Celestron C90 Maksutov Cassegrain 1200mm focal range mounted on Sony A100.lsisaxon, looks really good but the slow shutter causes overexposure and the glow around the Moon. It may be the humidity in the air also contributed to the glow, but I think you should have had a bit faster speed.
Mdzmr, there is no EXIF, but my guess is too much camera and hand shake in combination with overexposure. The Moon is a sunny spot and is best taken under full manual control. 1/250s, f/8-11, Sunny day WB and at lest 200mm lens is a must to get good results.
Ooops, I missed that part. I envy you for the lens.Olyflyer, I use Spotting Scope Celestron C90 Maksutov Cassegrain 1200mm focal range mounted on Sony A100.
It can also be that the day you tried was a bit too foggy or humid. Another thing which came to my mind is mirror lock to stabilize the camera. I think that is very important with the focal length. I'd set at least a 5 second self timer (or use a wire) to trigger the camera and set the mirror lock as well to make sure there is no shake when the shutter opens.Thanks for ur comments. Will try another attempt during the half moon.
Thanks. I suspect is the mirror slap which cause the vibration.Ooops, I missed that part. I envy you for the lens.

Good luck next time.
