I returned to my white light solar filters project this afternoon. The seeing was too poor for a real comparison and clouds kept time to a minimum. I was however able to try my Baader white light filter with a stacked UV/IR Cut and #58A green filter. Here's a crop of sunspots in AR2612:
With the mediocre seeing conditions, I'm quite pleased with the results. I'll have to wait for better conditions over enough time to compare my other filter combinations.
