Hi. Got my new camera yesterday ASI294MC PRO. Tried it out and this is a simple stack of 6 180s subs gain 200 on a SW Esprit 80 f5.
With that gain and 180s, shuldn't i be able to se anything of the nebula?? Am i missing something??
Using ASIAIR to control the camera.

Yupps. It spot on.
When i stretcht it in ps i can se the nebula but thougt that i would be able to se it in each sub. 180s, gain 200 on a Esprit 80 f5.
Was thinking if i where missing som setting in camera or if my camera was broke or someting.. Maybe this Nebula is wery faint, will try another one next time...

Maybe some nebula is very faint and you need to stretch the image to let them get more obvious.
You can also try to extend the exposure time.

This is normal. The nebula is so faint that with a simple stretch on a single sub it still doesn't become visible. This is exactly why we take many subs and stack them. Don't worry about it and keep on imaging. This is perfectly normal behavior.
