Description

This was very difficult to process, and a nightmare to capture. The recent relentless wind and rain, has pushed me very hard and truthfully I could have done with another 50% in Ha and at least double in the OIII - but this is the best I can offer - the weather still will not give me any further opportunities for this. I hoped to be able to squeeze Sh2-102 into the frame, but I could not quite do so! Anyway, this is the best I have ever captured of this tricky object, and I am pleased. I took 87 Has and 102 OIIIs, each at 4 minutes in exposure time. This equates to 12 hours and 36 minutes. Hope you are all ok and Happy Christmas - I will take this opportunity to say so...
