NGC 4725 in Coma Berenices.

Hi,

NGC 4725 is magnitude 10.1 with a diameter of 10.4 arc minutes.
A challenging galaxy from my location, it's maximum elevation is 30 degrees.

Quite happy with what I plucked out .
As you can see from the original stacked image there's a lot of red coming through to elevation variable seeing.

8” F/4 astrograph , baader type 3 coma corrector,. HEQ Pro 5 mount, orion mini guider.
Camera.
Unmodded Cannon 1100D plus cooler box. 32 subs x 2 minutes at ISO 6400. Stacked in Deep Sky Stacker .Processed in Photoshop Cs2..

Cheers,

Justin.
