Golden Handle with ASI2600MC and Nikon D7500


This evening the "Golden Handle" or "Jewelled Handle according Patrick Moore" is visible on the Moon's disk. The “Golden Handle” effect is produced by way the sun strikes the curved Montes Jura mountain range surrounding Sinus Iridum on the north and west. 
Following set up used : TAL200K f/8.5 with Nikon D7500 and TAL 200K f/8.5 with ASI2600MC.

Nikon D7500: ISO100 and exposure time 1/100s. Editing done using CS4.



ASI2600MC: imaging using ASIStudio. Both AVI files and png pictures captured. 
- AVI files too large to stack using AutoStakkert!2. Version 3 was downloaden and memory optimized using adaptive buffering. I choose only to stack 5 frames. It took 33 minutes to have a saved result. Stacking was done again without drizzle,  resulting in a working time of 20minutes. 



- png files are stacked with APP and final editing using CS4. In total 10 pictures, each 52ms, are stacked. This provided the best result.
