Hello all,

 

I recently tried to image Saturn and Jupiter for the first time with my 150mm Mak and ASI178MC on a GEM28 mount. I use AS3 for stacking and AS3 or RS6 for sharpening. Other than that, my processing capabilities are really limited. I was wondering how much better could the results be with more processing. Hope anyone will find some time to give it a try. I will also be gratefull for any comments on the imaging details or work flow.
The RAW AVIs (will take some time to upload), AS3 PNGs and full size final images are in the following link:
https://www.dropbox....i7cbt-jUna?dl=0

 

The details for Jupiter image from 23.7 at 39° elevation:
ASICap, 90s video at 8bit, binning 1x1, 1024x768 pixels, 350 gain, 5ms exposure
20% of 8,900 frames stacked
Wavelets and rotation in RS6

The details for Saturn from 18.7 at 36°:
ASICap, video at 8bit, binning 1x1, 1024x768 pixels, 350 gain, 15ms exposure
16% of 7,600 frames stacked, AS3 sharpenning
Rotation in RS6

You are welcome.
The second AVI is still uploading. It will take a few more hours.

Thank you! I'm very interested as I have a 150 here and want to give it a go.  :)

I do not understand all this stacking and stuff but I do like to play and try to learn. I did a fast click and drag and if I could get this kind of data with the 150 here I would be ecstatic, I think you did quite well. Hope a pro will grab the video files and post also.  smile.gif

I get what you did with Jove and I'm going to keep on playing and hopefully learning. Thank you again for taking the time to upload and share. waytogo.gif

Thank you.

I think that your version of Saturn is brighter and somehow more appeling than mine. What processing did you do after stacking and sharpening?

I hope that more of the forum members will give it a try.

Very nice images. I have a try with the freeware paint.net and the plugin Majics color abberation tool smile.gif

Here is a LINK to my tip

and here is a quick editing in paint.net

I only used AS and RegiStax and in RegiStax tweaked the red and blue channel a wee bit. Sadly I do not write anything down because I'm just dragging and clicking, trying to learn. Oh, I did export from Gimp to the png / jpg to post here. I too wish more folks would do your data and post how they arrive at their finished image. Hint anyone...  praying.gif

I read a little about ADC and learned about RGB aligning. I will try to use RGB align both in AS3 and RS6 and see if it makes any difference.

You have some nice data here!  My version of Jupiter:

 

2021-07-23-0130_2-CapObj_Drizzle30.png

 

I stacked 30% of frames in AS!3, using 3x drizzle. Sharpening in Registax, colour balance and some other minor processing (unsharp mask/Gaussian blur/noise reduction) in Photoshop.

 

Suggestions for next time: Use a 2x Barlow, which will get you close to your optimal focal ratio for this camera/scope combination. And record with a Region of Interest selected (ie, reduce the region around the planet that you're recording). The size of the ROI places limits on the frame rates you can achieve, and it's best to have as little empty space around the planet as possible.

I tried two different routes for both videos:
  1. RGB align in AS3, then wavelets and RGB balance in RS6

  2. All adjustments including RGB alignment in RS6

 

The first turned out the best, but the second is still better than not RGB aligning at all.

I added all the versions to the link in the original message.

 

Here are the better results for my opinion, looks like a significant imorovement:

Thank you.

I am already at f/12 which is exactly 2.4 microns x5, so I think that no barlow is needed in this case.

You're correct. I misread your signature and thought the scope was f6.3.
