I've been having trouble figuring out what to do on full-moon nights this time of year, as anything that would be worth checking out in narrowband is too small for my relatively short scope. I decided to try an entirely new type of target to me—globular clusters—and started with M13. 30s exposures seemed to make sense here, as I really wanted to try to spot the propeller and the moon threatened to wash out the background. I've tried to emphasize the propeller, at a cost of a bit of the cluster's overall brightness and size... but it's there! The AP08CC's small pixels, a large dither, and 2x Drizzle really helped here. I'm still struggling to get happy with my star color (and to get rid of the weird hard-edged halo the brighter ones seem to have) but am happier with this attempt than the last. Thanks for stopping by

BackgroundNetutralization
Color Calibration
Gradient Correction
BlurXTerminator
Generalized Hyperbolic Stretch
Curves - c* and sat adjustment
Star De-Emphasis Script - on starfield, leave cluster untouched
StarNet - create starless and starmask
Topaz Denoise on starless (can’t afford NoiseXTerminator, Deepsnr & NebuNoise produce artifacts for me for some reason. But they would probably be great for you! Try em out)
