Hi all, recently I took a video of the Sun with my DWARF II telescope for further processing with PIPP, Autostakkert and ImPPG. I‘m very happy with the results (you can find the image in my profile) but I noticed I‘m getting artifacts from the square pixels (visible on each 45° position on the edge of my image, they become more apparent for stronger processing). I thought about countering this by taking videos with slightly different orientations and using the frames of all videos for a single stack. Is there a way to automatically align the orientation of my frames to a given reference frame? Doing this by hand would definitely not be feasible. Or is my idea just not suited and I just have to do with the artifacts? Thanks in advance, Jan |

From my perspective here, I would rather take more frames in a narrower amount of time (check if your camera allows 30 or more frames per second). The sun is a dynamic object and besides, you would avoid all that derotating concern. For instance, just 30 secs and 30 frames per second would yield a total of 900 frames and taking the best 20% would provide 180 frames of pure quality data. Cheers Guy |
