The Moon with new (old) telescope

 A few months ago, I aquired an old Klevtsov-Cassegrain. I have been itching to try it on some high-resolution work. But weather and other reasons have made it impossible. Until yesterday. The moon was high, and a few days away from full. So there are some regions on the western parts that makes a great relief. And I wanted to capture that. I didn't care to take photos of the rest of the moon, as it is boringly flat. The telescope proved to be pleasantly sharp. I could even make out a number of cratlets in Plato. Although they aren't showing up at circles, they are obvious from the lightness compared to their surroundings. I will try later to picture those when the shades are different. And the atmosphere is calmer.

Tech data : Tal Klevtsov-Cassegrain 200mm F/10, ASI178MM 6ms exp, Gain 150, SharpCap for recording, AS!3 for stacking (20% best images), RegiStax 6 for wavelet sharpening, Image Composite Editor for stitching. 

For full image, click on the image, then open it in another tab. Then you can zoom to 100%. The original image is 7500x3500 pixels.
