Narrowband image through Ha-OIII on a color camera. Processing in Siril: cropping, gradient removal, green noise removal, automatic histogram stretch, black level. Stars untouched. Original color, without photometric calibration.

Further accumulation apparently no longer makes sense.

For now, I have this as the best result of shooting under the conditions of the "white" nights of Novosibirsk under the waxing and full Moon. Shooting was done on June 7, 11, 12, 13.
