Inspired by Dennis' absolutely amazing image, I tried AviStack for the first time today. What an amazing program, although I have to learn about appropriate settings as it took hours of computer time. Nevertheless, a much better job of sharpening the photosphere granulation evenly than Registax could manage.
4" refractor, Baader solar film + red filter, Sky-nyx 2.0 @ 66fps. Monochrome image with a bit of colourizing in Photoshop.
A nicely captured and processed AR1040 Graeme – well done for conquering AviStack too!
Once you select P1 and P2 and align the frames, I found that dragging the “slider” down as shown in Fig 13 on Page 14 of the manual (Deviation of P2 to P1) helped reduce my processing time from well over 2 hours down to around 15 to 20 minutes.
Thanks for the tip Dennis. I did reduce this substantially -I think the problem lay in the settings I applied for alignment area size and search radius. It's a great program for this kind of work though, or lunar images with detail across the entire frame. I had 1800 alignment points going. Can't see Registax coping with that.
Nice job Graeme, good to see more solar images being posted. It is great to follow the changing morphology of solar activity, it changes over such short time scales. Hope to see a continuing escalation of activity on Sol.
