Here we have a look at the rarely seen Cederblad 30 reflection nebula and LBN 768 - This has been, by a long way, my most difficult target to date. I shot over 200 lum frames of which only 72 could be used due to background being high (net effect of altitude and general seeing conditions). Only for a brief period was the darkness suitable for shooting this image in the UK. To add to the complications even when the data was acquired it was extremely difficult to process. With 72 subs the data was relatively clean but very weak still. Overall it is probably a little softer than i would like but the data breaks down very rapidly when pushed any further. Or to put it another was I exercised artistic license to present the best version I could where required.
Not a target for the feint hearted and ideally one only for very dark sky locations. All that said it was fun to process and the challenges it presented forced me to find a few more tricks to get it to this state.
Hope you like.
