M1 Reprocessed


Since I could not manage to do any imaging for almost two weeks now, I decided to reprocess the M1 data I had with the IR filter. Same data as the one posted on December 11th, but this time, I used better black and white point setting and also deconvolution scripts on the L master frame using the scripts developed by Robert. This did wonders. I used to cycles. The first cycle was gaussian kernel with 5 iterations and 4 pixels. The second cycle was again a gaussian kernel with 3 iterations with 2.5 pixels. In both cases the Standard deviation on the background was 6 (derived from the information panel of Maxim DL in aperture mode). This gave me a much sharper L master. The LLRGB was combined in PS CS2. Using some basic curves on R,G and B frames (from Ron Wodaski’s tutorial) and also black and white point settings. I also used DDP script for photoshop. Layer 1 was 40% opaque. You also notice that with the deconvolution all the doubles are also split nicely. There is some halo around the big stars and that’s probably because I pushed the deconvolution too far. I think the color balance is also better on this one. Although I still have no clue on how to do the color balance right.
