AR2665 - Image and Hi Res Animation - July 14, 2017
Had pretty good seeing again this morning, and had the setup dialed in pretty well. This was the first capture of the day. I manually triggered about 100 captures, 10ms, 200 gain, 1000 frames and I'll see what I can do with an animation, or at least a series from the morning over 3 hours. I have a couple other targets, but I started processing the animation frames, so they'll have to wait. The below was shot @ 7050mm with CPC925, Aries DERF, Baader 3x telecentric, Combo Quark, ZWO ASI174MM camera. Processed with AS!3, AstraImage and Photoshop. Comments and suggestions welcome.
This still of AR2665 was from 100 frames stack...(click for bigger view)...
So here's the animation. 102 frames, captured between 9:22am and 12:07pm PST. I need to work on my Newton's Ring removal. I used a tilt adapter, but not well enough apparently. I think it would be pretty clean without them. I might go for one of the adapters you can adjust without a tool. Mine require an allen wrench and usually camera removal, which makes adjusting difficult. Processed with AstraImage, IMPPG, DVS, Photoshop and PIPP.

Brilliant stuff Nick! Easier to see the effect of sharpening at a smaller radius in revealing the finer details, you're not getting those halos around the detail anymore. Maybe work on fewer sharpening iterations to reduce the dotty noise a bit. You're coming on leaps and bounds with both your technique and handling of this system though, good stuff chap! The flow of plasma in the animation is stunning - I wish I could image the sun for 3 hours, normally for me it is 3 minutes in the cloud gaps

Thanks much Mark. I have been keeping your sharpening advise in mind as I process, and feel I've been improving. I have some habits that are hard to break. I cleaned up the above animation a bit, evening out the levels frame by frame in Photoshop so there's less strobe effect. Anyone know a tool that'll even out levels automatically? Can't do much about the Newton's Rings at this point though.

Nice animation, Nick. Demonstrates the complexities of plasma flow in these regions.

The animation came out wonderfully, Nick.
As for strobing, someone has mentioned using a deflicker video filter in VirtualDub (I think). VD can handle a sequence of image files and animated GIFs too.

Hello Nick.
Congratulate your progress is not overlooked! Now you just have to get rid of these interference rings and then it's great!

Thank you very much everyone.
Time to get testing with the tilt adapter. Those interference rings have to go.
GreatAttractor - thanks for the tip on VirtualDub deflicker...now installed and using.
