Sunday night, Aug 10th was a much ballyhooed Super Moon. It was closer to us than average and therefore slightly larger than normal and particularly bright. I didn't pay much attention to it but I should have. I imaged Sharpless 2-115. Normally, I don't have trouble imaging in HA regardless of the phase of the Moon. But I ended up with very significant gradients. That combined with the dimness of SH 2-115 led to trouble processing.
I ended up stacking before and after the meridian flip separately (since the gradients were opposite). Then I applied the DBE tool in PixInsight to them separately to get rid of the gradients. Then I stacked the results together. Processing then proceeded as normal. It was more trouble but at least it did the trick.
This one reminds me a bit of a brain with the various folds. The embedded cluster in the middle left is Berkeley 90.
