Galactic Neighbourhood

Astrophotos of our immediate vincinity.  So to speak our inner galactic neighbourhood. Planetary nebulas, galactic clusters. Large emission nebulas are to be found here or here in false colors.

Object: M1, Borgfeld, 2018, Oct. 9th
Scope: Skywatcher Esprit 100 ED at f/5.5
Camera: Atik 490EXm, 12x4min LRGB each
Mount: Avalon Linear
Guiding: ASI 290MM 60/240 Finderscope, PHD2

Object: NGC 7293, La Palma, Athos, 2018, Sept. 6th
Scope: Pentax SDP125  at f/6.4
Camera: Atik 383 L+, 19 x 4 min LRGB, 5h 04min
Mount: 10Micron GM2000
Guiding: –
Processing: SQM Pro, PI, PS
Remark: The Helix Nebula shot during a good night at Athos Centro Astronomico. The raw frames had a very good SNR and no gradients. Hence I had not to process the pics really much. Only slight denoise, color calibration, selective sharpening, masked stretch and manual stretch, LRGB combination, selective adjustment of saturation using different masks. Final cosmetics in PS.

Object: M17, La Palma, Athos, 2018, Sept. 5th and 6th

Remark: For the eclipse I went out to the field with my family. The photo was just a trial. Actually I haven’t been prepared for anything… The night was unusual hot for a northern german summer night as the whole summer was.
