I took my data from Nov 29 and made an animation sequence out of it.

 

Due to size restrictions on CN, I can only share via links to other services.

Imaging details:

- WO 132FLT w/FLAT8 Reducer (F/5 @ 667mm FL)

- ASI294mm camera (L filter). 60s subs at 121 gain, bin1

- CEM 70 mount

Fantastic animation Ryan!! Did you dither when imaging? What program did you use to stack the frames? I had a hard time stabilizing my image when I stacked the frames and stars were just moving all over around.

Thank you!

 

Yes I did dither, I think every 15 min or so.

 

Then I just used WBPP to flat subtract and register the images.

 

From there I resampled the data since I did not think I needed high resolution. (I used PI Image container for this)

 

Then I normalized the images (I used Tycho, an asteroid tracking software, because I was not exactly sure how to accomplish this in PI but I bet someone can tell me it is easy in PI :) )

 

Next I applied a common Histogram Transform to each of the images and then PI's batch convert to make them all PNGs.

 

I usually use PIPP to make animations, but it was crashing everytime on this data, so I used an online tool (https://ezgif.com/)
