Finally got round to processing my Mercury data from 12th May. Data was very difficult to process as seeing was poor. 3 videos using Baader 685nm IR filter yielded nothing but more successful with the Astronomik 642nm filter which gave 3 videos where faint surface details matched after processing.

Breakthrough in processing was to use PIPP in standard quality algorithm to process each video down from 27k frames to 2% of that. Quality sort much superior to AS3s! Then used 80% of those frames in AS3 with NR of 7 and single AP box of size 104 with 1.5x drizzle. In Registax Linked Gaussian first layer 0.75denoise 0.16sharpen at 100% then histo 9/136 and gamma 0.5. Combined all 3 videos in Winjupos then Astra Image deconvolution in PaintShop to bring out details.
