Description

AVX went crazy in RA and I couldn't find a solution. This mount behaves different on different days.
Also, I cropped the image to 1/5th due a usage of a visual reducer with heavy coma.
Hence , some cosmetics on elongated stars were applied.

But a least I was enjoying a clear sky and this beautyful Lil' Pinwheel Galaxy. What a great galaxy !
