Photo description / processing

Sh 2-101 Nebula (Tulip Nebula) is an emission nebula located about 6000 light-years from Earth in the constellation Cygnus, with a size of 70 light-years. It got its name because in photographic images it resembles the outline of a tulip. The imaging was conducted in July 2025 in Kalmykia, Voronezh Oblast (near Boguchar).

I have the same telescope and camera. And an Ha+Oiii filter, but 6 nm. I’d be really curious to see the difference compared to your 3 nm. Your Tulip Nebula image is more interesting. If you have the time and interest, try shooting M1 in Taurus, the Crab Nebula. That’s exactly where this filter works well. It would be interesting to compare the results.
