Dear all,
While planning a portable setup for astro trip soon, I was testing the rig last Saturday night to see whether the small 80mm aperture was able to capture fine details of DSO.
As the sky was clear after midnight, one of the tested targets was NGC 281.
With the help of Petming, I tried to pull out some Ha details.
Here is the stack of 5 images of 15min each of NGC 281.
The capturing details are set out at
