I picked up this remnant from reading this paper and ended up taking 7 hours of data across several nights - as you can see it hardly shows up , and my field of view was a little cramped.
Taken with the Sky90 and the Atik 490ex with the astrodon 3nm Ha filter.
This image contains the optical counterpart of a supernova remnant
This image was autoguided using my homemade off axis guider with Lodestar.
