Thanks, Bart, glad you like it.

As for your setup - this is with a PST etalon, correct? So the Intes can manage the required 200 mm backfocus, or is it some other approach?

Great result, the high resolution is immediately noticeable.

I wrote the FlyCapture (i.e. "native" PGR) and IIDC drivers for PlanetaryImager (IIDC a.k.a. DC1394 is a universal protocol supported by all PGR's USB cameras). Marco (PlanetaryImager's author) does publish macOS builds (.dmg files) in the Downloads section, but likely they do not have FlyCapture su...

What a catch, Stu. Super-thick curtain blowing in the (solar) wind.

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.

My approach:

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

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.

Wonderful animations. Plasma rain blowing in the wind.

I have a Borg helical focuser and a custom T2/C-mount low-profile adapter, see the second picture in this thread: viewtopic.php?t=18394

Perfect! Those boiling ARs at the limb are the best.

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.

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 ...

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...

FLIR (formerly Point Grey) have made a “periodic table” of camera sensors with data on 120 models “from classic CCDs to the latest CMOS technology”: https://2.bp.blogspot.com/-H7FKWkZdizQ/XBp6DZM9dtI/AAAAAAAAXyw/euZLBSLxkJ4IiaQbNPrcEMTbbZIMLE8jgCLcBGAs/s640/Periodic%2BTable%2Bof%2BSensors.png Direct...

even the Lunt 50, like the Lunt 60., seems to have a objective with single lens Hmm, interesting. Where does the image come from? I just double-checked my specimen (purchased in 2015) and it seems to have a doublet. I mean I didn't disassemble it, but it shows two upright minified reflections of my...

Have fun, everyone!

And don't forget to check out the new improved "About ImPPG..." dialog

Good luck with the setup, Alexandra.

PS here is a piccie of the Celestron with the Aries ERF finally fitted

This is shaping up to be a very interesting season!

Hi Stu, I love the idea. Here are some of mine, technical details are in the Astrobin descriptions.

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.

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.

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).
