Photo description / processing

The Squid Nebula (Ou4) and the Bat Nebula (Sh2-129) in the constellation Cepheus. The object is very faint but beautiful and interesting. This version has a golden-gray tone; there are also versions with white and just bicolor, but a poll in the group showed that most people prefer this one. Captured 50 km from Rostov-on-Don over 9 nights. Processed in PixInsight and Photoshop, without AI plugins. P.S. The stars were also captured with the Askar, just through a mask — I like it better this way.

Wow, what a bright and dense Squid Nebula. I once took aim at it and even fired off 5 or 10 one-minute shots.

On a single 600-second exposure, it is barely visible; one-minute exposures miss it entirely.

Mid-summer, everyone is focused on shooting the Squid Nebula... Great work.

To be honest, I wasn't planning to shoot it at all — it wasn't even on my shooting list. I was thinking of shooting Leo, but someone showed me the Squid, and it fit my schedule better since it rose to the required altitude earlier.

I've been shooting it since June, a couple of nights weren't enough) hoping to finish it during the next new moon.
