Lunar astroshots

Lunar astrophotography has its own rules, different than deep sky astrophotography. In this case we have much light, and picturing technique is to make a movie with short exposure times, like 10-100ms, so seeing effect is somehow limited. Then using appropriate software (like Registax) we can select best frames, align them and stack with nice effect.

Another trick is to use IR filter that passes only infrared light. In this range seeing effect is lowest, and effectively we can have better resolution in the final image. Detector used for making these pictures is QHY5 camera, connected to GSO 150/750 telescope with Soligor x2 barlow lens. Effective focal length was 1500-2200mm. There was also Astronomik IR 742 filter in the optical train.
