Seeing wasn’t much better today. Lot of wind, causing much shaking during recording. So lots of frames were unusable.
SW Esprit 120 + Daystar Quark Chromosphere + QHY5L-IIc (with TS 0,5x reducer). Stacked in Autostakkert 2.5 and processed in Photoshop. Sunspot is AR 2305.
First I post the invert filter applied to the image. Giving best result, compensating a bit for the bad seeing conditions.
And below original processed without invert filter.
