I am working on the Helix Nebula in narrowband with my OSC camera, and would welcome suggestions for how additional exposures from my Bortle 6/7 sky might improve the image below. This represents 66 x 5 minutes exposure over three nights in the short window when it is available between my roof and my neighbor’s roof this time of year.  While I know that you cannot go wrong with more data, I am not sure how great an improvement I might find if I am able to double the number of exposures for this target.

 

The image was constructed from an 8” LX200 ACF telescope with an Optec Lepus focal reducer, and a ASI294MC Pro camera, and an Antila ALP-T duo narrowband filter, using an ASIAIR plus controller, an Ioptron CEM40 mount, a ASI294MC-Pro camera, and an ASI OAG with a ASI174mm mini camera for guiding. Processed with APP and PS.

 

Thanks!

I added 23 more frames last night then selected the best 80 based on quality score in APP to produce the image below. Perhaps just a bit improved with more definition.
