M8 Drizzle Comparison
I used DeepSkyStacker to drizzle combine 10 frames, 4 minutes each, of H-alpha data taken with my SXV-H9 and an Astronomik 13nm H-alpha filter. I used a Canon 200mm f/2.8L lens. For comparision is a non-drizzle version, enlarged 200% using PS CS3, method Bicubic Sharper. I tried all the Bicubic methods in PS and I thought this looked the best. The others where more blurry.
Here is the entire image, reduced 33%:
