Re: IMPGG tutorial

Have a look at Jason's video covering his ImPPG process:

Because I am greedy (not really) if you have a post processed version of those files and steps well take those as well,
Done - uploaded raw stacks, processed images and ImPPG settings files for each.

Re: Prom Animation Wed 19th

Great animation, Stu. Too bad there wasn't a larger prom to capture, but the detailed spicule action is great.

Re: Anybody want to share their unprocessed source AVIs

Hi Jack,

I'll upload some AVIs overnight. Of course I don't store full material from each time lapse session (100-200 GB), but I keep 1-2 best videos for future experiments.

UPDATE: already uploaded, have fun.

Re: New version of ImPPG

Alexandra, which Windows version do you use?
Did you perhaps unpack ImPPG to a folder containing the previous version? If so, try unpacking to a fresh folder and running from there.

Re: A Grand Post-Processing Thread!

I think I learned about the L-R deconvolution from Michael Wilkinson on SGL forum. It seemed like a straightforward enough (and fun) to implement method, and at that time I needed something more convenient than R6 for batch processing. The tutorial links on ImPPG's homepage should be useful. In the ...

Re: A Grand Post-Processing Thread!

Bruce, it is my understanding that for (our) solar imaging, when sharpening a stack, we need to remove the blurriness caused by 1) atmospheric turbulence (even though the stacker tries to choose the sharpest image fragments, it has to use some blurrier ones too), and 2) shift-and-add procedure (whic...

Re: Grasshopper3 how to ??

You need something like this: Baader C-Mount/1.25" adapter, then you can plop the camera into any telescope. FireCapture should work fine for video acquisition.

Re: Lunt LS50THa modification to 200 mm aperture

Back focus = distance from the rear of the OTA to the OTA's focal plane. Etalons, telecentrics etc. need to be inside this distance. RC has quite a lot, SCT somewhat less, and adding a focal reducer moves the focal plane in, so reduces back focus.

Re: Lunt LS50THa modification to 200 mm aperture

I would fear the back focus would be insufficient (Lunt 50 needs some ~180 mm). With an SCT it would be easier to simply attach a PST (which works at f/10).

Re: Imppg file type question

Hi Don, ImPPG is for post-processing still images (stacks made with e.g. AutoStakkert!3) and alignment of images for a time lapse. For stabilizing a video like this you'd have to convert it to a series of frames. It'll be easier to use PIPP . But if you meant to stack this video, just feed it direct...
