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.

One week ago I collected some light from the cluster NGC 6823 and the surrounding region!
Now I finally had the time to finish the processing and use my new processing workflow. Always impressive to notice the gigantic differences the processing makes... currently my nebulae are quite red heavy, but I still like it.
