I hope you can forgive me for an unoriginal target but this is one of those objects you just have to shoot for yourself. I find myself returning to it with a different scope and camera this time - and getting a (for me anyway) pleasing result. Last time was a VC200L and unmodded 20D this time a 127 ED and Opticstar 145m with Nb filters. This is about 50 mins with each filter - I would have got more but my guiding session gave up - I think it is bad cable. Just for fun I have attached my previous best effort at this target.
