NGC 4449 (Caldwell 21, UGC 7592 and others) is an irregular galaxy located approximately 12 million light-years away in Canes Venatici. It is similar to the Large Magellanic Cloud and appears to have a faint tidal tail that can be seen toward the top right (northwest) in my image.

 

Luminance – 36x600s – 360 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

 

480 minutes total exposure – 8 hours

 

Imaged over seven nights in April and May, 2016 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Dan,

Yes-Wow. That really a nice capture and process. I can see the tail nicely when I turn my monitor up.

Very good result!

One question: which typical seeing do you have in your imaging location? I suppose a very good one as you work at 2432mm focal length and small pixel of 8300 sensor.

Irregular galaxy is an understatement - Wow, looks like NGC 4449 had a bad day back in the past.

 

Most excellent capture.  That is some impressive image scale as well.
