 The sun had only one tiny spot seen as a small dark pinprick with some lighter faculae here. Fortunately, the prominences were large and active, and some filaments were also visible on the disk. I was able to use a new homebrew camera adapter here for the first time, allowing no rotation between shots and making stacking a snap. The granulations clarity is a tribite to this new tool.

Processing: Extracted disk from green channel, prominences from red channel, and averaged 2 to8 images. Applied midtone curve adjustment in PS, then wavlet deconvolution, and dynamic background flattening process in Pix Insight. Combined and colorized disk and prominence image in Photoshop per accepted standard coloration creteria.
