This area of sky is an interesting one for widefield imaging. The RASA 8 did a nice job of capturing some of the interesting DSOs in this area. The images below are an interesting comparison. The first is a 1.7 hour integration (25 second individual frames) processed and with noise reduction applied. For the second image, I added year old data from my last picture on the nebula, for a total of 3.7 hours of integration time (cropped differently due to framing differences in the imaging runs). I processed this image using a similar workflow, but with no noise reduction. I present them for comparison purposes. Is 90 minutes or so integration time the sweet spot, or is the subtle improvement in the second image worth the extra time?
The trials, tribulations and small triumphs of a Charlotte, NC astronomer imaging under Bortle 8/9 skies.
