Description

First image with iOptron CEM40EC using DSLR and 200mm Canon lens. 30 frames at F5.6 and 8 frames at F8.

Original image used all 38 frames but felt processing was a little too aggressive using Nebulosity. Also, reviewing images taken at F5.6 showed some distortion along edges. The final image only used the eight frames taken at F8 but noticeable improvement in star shapes at edges seen. However, now noise was a factor with only the eight images. In the end, I'll need to use at least F8 when imaging with the Canon 200mm lens and the 1.4x extender.
