Jim Honeycutt reminded me this past Saturday that RegiStax 5 is available in beta, so since I haven’t been able to image lately, I decided to download it and give it a try on some earlier sets.
This image was processed with version 5. I hadn’t bothered to process this set because of the softness of the avi’s. This one was taken at 07:37UT on February 1st, 2009, CMI: 161.5 CMII: 122.9 CMIII: 14.2:
The avi’s were bouncing around somewhat with a seeing estimate of 3-4/10. It was taken with a Skynyx2-0M and C14 at F/25.71; Custom Scientific RGB filters.
I was somewhat happy with the results, especially since I’d given up on this set. Registax5 seemed to pull out some interesting detail from very limited data.
The following is a comparison of the same image processed by Registax4 and 5. In this comparison, the v5 image seems to have more noise, but I may have gone too far with wavelet processing on my first try with v5. I typically apply wavelets modestly and let PhotoShop do the rest, but I wanted to test the limits.
I’m happy to see progress on this excellent FREE software for stacking astronomical images. Being a programmer myself, I know that developing software like this takes hundreds if not thousands of hours of work by dedicated individuals. Many thanks to the Registax version5 team!
