Markarian's Chain in Virgo

My own Hubble View! These galaxies lie between 10 to 50 million light years away. How many galaxies do you see?

A pretty tricky part of the sky to image, really. You're utilizing almost your entire field of view with an 80mm scope, so dealing with all that comes with wide-field. This is the best iteration I have processed to date from two night's of imaging. Learned a lot, but have a way to go to get this the way I want it.

Image Details:

* Imaging Scope: Astrotelescopes 80mm ED Refractor

* Imaging Camera: Nikon D7000

* Guiding Scope: William Optics 66mm Petzval Refractor

* Guiding Camera: Orion Starshoot AutoGuider

* Mount: Celestron CGEM

* Exposures: 32 * 8 minute lights, 21 * 8 minute darks, 40 bias frames

* ISO 1000

* Aligned and Stacked in Deep Sky Stacker

* Post-Processing Dynamic Photo HDR, LightRoom and Photoshop.
