ha or LP filter?
Hi all,
I have a 10" newt and would like to improve my imaging quality. I currently run with no filters with my prime focusing using a full spectrum modified Canon 60D unguided to which I have had some good results. However to eliminate skyglow from my backyard obs would a Light supression filter suffice or should I consider entering the realm of narrowband and acquire a h-alpha filter. I feel the later would pose problems when trying to focus and frame DSO's plus having to remove the filter to collect standard LRGB subs which means removing the camera and attempting to refocus and align to match framing from ha subs.
Note I have only ever taken max 40sec subs for most of my imaging to date.
Any thoughts would be greatly appreciated thanks.
