Hi.I had another go at Saturn last night in much better conditions. Glad i did as the result is a marked improvement on previous efforts.
However, i noticed i am getting some "ringing" artifacts around the planet and i'm not sure where the planet's rings start
I took about 4 AVI's, and discovered this in the last 3 times i went to process the AVI's.
The first AVI i did did not appear to have the ringing present.
Just wondering if this is normal and people process it out, or maybe moisture in atmosphere, or colimination need to be done?
Here are the stats..
1st pic processed image
2nd pic showing the ringing more (straight out of AS!2 and wavelets stretched to the rhs in Registax6)
2872 frames original avi ( don't know what was stacked in the end)
ASI120MM CCD
SW 8" f5 Newt
(2) 2x barlows giving me a focal length of 4000mm.
Neq6 PRO.
AVI processed in AS!2
Wavelets in R6
Thanks.
Steve.
