Another image I could keep reprocessing forever and never be entire satisfied with: the Rho Ophiuchi Cloud Complex.
A total of 3143 individual 30 second exposures went into this 4 panel mosaic image (over 26 hours total exposure time), all taken with my little Seestar S30 Pro smart telescope in my suburban Sydney back yard (Bortle 7, at least). Processed in Siril with RC Astro, SyQon and VeraLux scripts. Scaled down to 50% size for posting, full resolution version here: https://drhotdog.smugmug.com/Nature/Seeing-Stars/i-C6FNrn7/A
The big challenge here is removing the sky background gradients when there's basically no truly empty patches of sky to use as references. To really improve on this I think I'd have to take my Seestar away from Sydney's light pollution and get images that don't have lots of background light in them to start with.

Here is a lesser-known nebula: #NGC6820, and the open cluster #NGC6823 .
This shot covers about 1 degree by 1.5 degrees, and is the result of about five hours of data collection over the course of three nights, using two #DwarfII smart telescopes.
1 hour's worth is without any filters, 1 hour is with a Svbony CLS light pollution filter, and 3 hours with a OIII/HII filter.
Then I fed the 1237 frames into #Siril and started crunching numbers. 72 frames were not usable, leaving me with 1165. These I stacked, and then ran through the "Hubblematic" #HubblePalette emulator and DSA Star Reduction scripts. Finally I did some additional reprocessing and smoothing with #GooglePhotos.
Most images of the area cover the cluster, rather than the rather large area of nebulosity that surrounds it, and just concentrate on the (admittedly very pretty) nebula around the cluster. This shot covers a much wider field, and even it does not show the true extent of this faint but magnificent region.
