Galaxies

Some views of the real outer space. Since my maximum focus lengh is around 550mm, most of the galaxies are shot with a very small scale. Anyway I’m always trying to get a good impression of these objects. Of particular interest for me are pictures with local objects of our galaxy and a real deep sky 0bjects. An example is the pic of NGC6946 and NGC6939. I collect this type of pictures at Close Encounters.

Object: Hickson Compact Group 68, May 5-7th 2018, Borgfeld
Scope: SW Esprit 100 ED with SW Flattener at f/5.5
Camera: Atik 383 L+, L: 34×8 min, RGB: 17/15/16x 4 min at 2×2 binning, 7 h 44 min
Mount: Avalon Linear
Guiding: ASI 290MM 60/240 Finderscope, PHD2
Processing: SQM Pro, PI, PS
Remark: A
collection of galaxies located in the constellation Canes Venatici at a distance of 100 million light years, containing NGC 5353, 5354, 5350, 5355 und 5358. North is up.

Object: Whale Galaxy and Hockey Stick Galaxy, 6 nights April-May  2018, Borgfeld
Scope: SW Esprit 100 ED with SW Flattener at f/5.5
Camera: Atik 383 L+, L: 48×8 min, RGB: 17/19/18x 4 min at 2×2 binning, 10h
Mount: Avalon Linear
Guiding: ASI 290MM 60/240 Finderscope, PHD2
Processing: SQM Pro, PI, PS
Remark: G
alaxies located in the constellation Canes Venatici at a distance of 25 and 40 million light years which probably have been interacting in history. North is up.

Object: M101; 17.02.2018 RGB; 09.05.2018 L; Borgfeld
Scope: Skywatcher Esprit 100 ED with small Riccardi at f/4.1 (5D) and with SW Flattener st f/5.5 (383)
Camera: Canon EOS5Da MkII, CLS, 28×4 min at ISO 800; Atik 383 L+ 24×8 min Luminance
Mount: Avalon Linear
Guiding: ASI 290MM 60/240 Finderscope, PHD2
Processing: SQM Pro, PI, PS
Remark: North is up. Just a trial not to waste an hour of clear sky… L taken later, again just a try to boost the DLSR shot with CCD Luminance.

Object: M81, M82 and NGC3077, March tp April 2017, Borgfeld
Scope: Skywatcher Esprit 100 ED with small Riccardi at f/4.1
Camera: Atik 383 L+, 11h LRGB
Mount: Avalon Linear
Guiding:Lodestar 60/240 Finderscope, PHD-Guiding
Processing: SQM Pro, PI, PS
Remark: Actually I intended to collect more photons than I finally did. The bright nights of the north german summer stopped me and I decided to start with the processing. Maybe I’m gonna add some light next year…  see picture page.

Object: NGC2903, 12./03., 07./10.20.04.2016, Borgfeld
Scope: SW Esprit 100 ED with SW Flattener f/5.5
Camera: Atik 383 L+, L: 17x10min, RGB: 9/9/8x10min, Ha: 3x20min
Mount: Avalon Linear
Guiding: Lodestar 60/240 Finderscope, PHD-Guiding
Processing: SQM Pro, PI, PS
Remark: SB(s)d galaxy in a distance of 20 Mio ly. North is up. The smaller one on the left hand is NGC2916.

Below a gallery of more galaxy photos  shot in earlier times. All photos are shown with their original description written after finishing the processing.
