using sharpcap pro and after using the brain to measure the light pollution, it suggested i use an exposure of 2.7 seconds and gain 61, brightness 12 for 1 hour, so i did and got this result of ngc 7331.

No filters were used. all my images are made using the relatively cheap zwoasi290mm.

this is test image 2 of the secondary mirrorless scope
