Это первый свет прямофокусного Ньютона. Над формой звезд надо будет поработать еще Сейчас в апертуру торчит внеосевик, видимо он дает такой эффект

The details of the galaxy's arms look magnificent, with great depth, super!!!!
A question about Gain: why 140? Did you arrive at that number through experimentation?

Regarding gain, it's simpler - according to the manufacturer's specifications, it's at this specific gain that dynamic range boost occurs.

New to me! Where can I find ISO data for the 2600MC Pro? I've never come across recommendations like this for my camera.
