If you don’t have very good control over your manual settings, or you can’t get a lot of images to stack, one solution that a lot of people use is to say “screw it” and just take a video. Usually, the power of the camera drops somewhat by going to video, but what you lack in initial power, you make up for when you take a video. For the ISO comparison, I shot the moon. Some of the manual controls in Camera FV-5 were overriding each other, but still, one way around a lot of short burst images is to do a video. Since Camera FV-5 doesn’t support video directly, I used the companion app, Cinema FV-5.
I shot one of the moon for 90s, and then ran it through the PIPP processor plus Auto-Stakkert. Here is the result, compared with the original single-shot earlier:
|Single shot||Video processed and stacked|
Obviously, something went wrong in the stacking process somewhere, which is part of the challenge of using videos — you have to convert them essentially into frames and then stack them one on top of another to get an image. More art than science at times and I didn’t go back to find the problem, partly as I’m lazy and partly as it is a bit overkill for a moon shot when the original has a fair amount of detail. If you want more than that, use a real camera!
I also did one of Jupiter for 80s, same processing:
No better than I had done earlier, although the relatively perfect roundness of the planet hints at the power of stacking if you can capture one in the first place that isn’t washed out.
And one of Spica, a single star, for 10s, same processing:
Not very exciting, but it can be done. Normally it would be done with larger fields, but well, my camera doesn’t do that. This is about the best I can get.
