Finally was able to process some of the videos from 7/17 - All shot with nice seeing with Celestron C14 XLT/Siebert 1.5x Barlow/ADC/Baader 1.5x IR Cut and ASI290MC

 

Saturn: This is one of the few times a 3x drizzle has actually given me good result. Most of the time my data results in a mush at that drizzle level. Processed in Registax and Curves in PI.

I did have few more videos and I tried to derotate them. The edges were getting weird artificats after derotating. After a bunch of measurement attempts, I gave up. This is 25% of the 5200 frame video. (I have it at youtube: https://www.youtube....?v=lArPbQz_X6I)

Fantastic results, what do you think your EFL is with that optical train?  I have a 14" f/4.5 (1600mm) native and have been using a 5x PM with my mono 290, and I'm thinking it's too much for the lower altitude planets this year.

That is beautiful.  I was wondering if you would share your exposure settings and what was the FPS?

 

Thank you,

Steve

I should be at 5900. .The Siebert barlow is supposed to be like the Powermate and should not have more magnification inspite of having the ADC between the barlow and camera. 

 

The critical sampling for the C14 with the 2.9um pixels of ASI290MC is 5x2.9 = 15 focal ratio. So I stuck to that. I did try with 2.5x powermate for mars but the seeing was terrible so I am not sure about that combination.

 

Austin is at 30N and the planets top off under 35 degrees altitude. But the ADC, when tuned, help a lot. Of course we are at the mercy of seeing as well..

Thank you. This is with 17 to 20 FPS. I kept the gain low (275) and had to push the exposure to 35ms (or even higher I think). Everytime I tried to increase the gain to get better FPS, I ended up with pretty noisy image . So stuck to lower frame rate..
