About this image

Lock down has meant I've been getting to grips with the Stellarmate astrophotography tool and having now got it working so that I could trust it to give me a good evening's viewing, I decided to go for broke and take a stack of images of this galaxy pair.  I've always known the more images you take the better.  But I had never really appreciated the impact flats and bias frames would have until I took this image.  The Stellarmate gadget has really made it easy to capture images I use the app on my tablet and can set up a complete astrophotography run and then step back and observe with my Skymax 127 as well.  Stellarmate's astrometry feature means plate solving can now ensure targets are better centered, or not, if required compositionally, so it makes astrophotography easier.

Processing was stacking in Deep Sky Stacker, main processing in Gimp, finishing touches in Photoshop elements and Neat image to tidy up some of the image noise.
