NGC 7822 Narrowband
This is a great target, having an interesting combination of emission nebulae and dark nebulae. I tried my hand at the Hubble palette, but used HOO stars.
I used an Askar FRA 400 telescope, an ASI 1600MM Pro, OIII, SII and Ha filters. I used 16 hours total integration. It was processed in Siril, Starnet++ & GIMP.
