Description

My first ever guided image, and my 3rd try on Andromeda.

While everyone speaks of M31 being a beginner target, I found it quite the contrary. My first try was washed away by the moon, even though I had a CLS filter. My second try was a moonless night however I used the CLS filter again, where I had to take 4min subs at 3200 ISO in order to get enough signal. But of course the image was beyond repair, the noise was way too much for processing. The reason was the CLS filter, blocking much of the light.

First image, no moon, no filter, 1600 ISO 100x2min subs. My best so far. Now I can proceed to other summer nebulae before its too late for them.

Final image 200x120s subs taken over 2 nights, and a softer processing with reduced stars.
