Here’s one thats been sitting on the hard drive for a couple of weeks – NGC891, I took it from the back garden observatory, it’s 17x10min subs,processed in Pixinsight and Photoshop (Setup was the usual, Altair F4Newt, QHY8 and Lodestar/OAG for guiding). Was a bit of a pig to process as I seemed to have a red halo round the middle third of the frame, I have seen this before and it appears to be some of the red light in the observatory leaking on to the CCD Sensor of the QHY8.
NGC891 is an edge on galaxy in Andromeda, it’s around 30 million light years away! Hubble has also had a look at this galaxy, it got a little closer in……. http://www.nasa.gov/mission_pages/hubble/science/ngc891.html
