NGC 4236

[Gabrielwiklund]

After 2 weeks of bad weather the skies finally cleared up and i could start collecting photons from NGC 4236 on Tuesday.
This Barred Spiral Galaxy is located in Draco above the Big Dipper and is a member of the M81 group of galaxies located almost 12 million light years away.

8 hours and 53 minutes total integration (533x60s collected over the course of 4 nights)
100 darks  
40 flats  
40 flat darks

ASI533MC Pro @ -10°C Gain 105 Offset 70
ZWO UV/IR CUT 1.25"
8" f/5 Sky-Watcher Explorer 200PDS 
ES HR Coma Corrector
HEQ5 Pro
50/200mm Guidescope
ASI120MM Mini
ZWO EAF
Software: EQmod,Nina,PHD2,Siril

I have not boosted saturation or sharpened the image since that did not improve the result in my opinion.

Clear skies

Very fine image of a galaxy that we don't see very often, thanks for sharing

Nice image👍

I had a go at this object in 2009, using my kit at that time of Vixen R200SS and Atik camera. I was surprised to see what I thought were 2 extra arms  of the spiral starting from half way up the centre. It took a lot of investigating to find that there are actually 2 galaxies one on top of the other: NGC4236-1 and NGC4236-2. Maybe this accounts for the extra arms.
