I'm pretty new to this whole astrophotography thing, specifically the whole image resolving and stacking part. I've been using registax 6 to edit the videos, and I think I'm pretty much done with an image of Jupiter I've been practicing on from a video of Jupiter I found on the internet. I was wondering what I should do to get rid of those weird ring things around the edge of Jupiter and maybe clean up and sharpen the edges all together. Any other tips you have that could make the image cleaner are very much welcome. Thanks!

I think the "...weird ring things around the edge..." is normal, I maybe wrong. I have seen it on images of Jupiter on other astronomy forums.

At this point I'd load the image into PS and make 3 layers out of it... I'd align the RGB channels to line up so that you have no more of that fringing in the middle of the planet on one layer, and each side for the remaining layers.

At this step just mask out the fringing layers, and you'll be left with a clean balanced image... You can use filters like sharpen, unsharp mask, smart sharpen, etc certain plugins like topaz to gently increase the detail.

I don't think RGB align is the problem (but yes the RGB align works in RG6).  It looks like the wavelets application is a bit too severe to me.  I gave up with RG6 as it is just too harsh on images.  I now use Autostakkert which is a much more user friendly programme (and it works on my MAC) and then I sharpen in photoshop in similar fashion to that suggested by @MarsG76.  There is some great detail in the bands on the image.

Thank you everyone for the help. I think I will try out autostakkert and see how it goes. I never actually expected to get help from anyone. Very friendly forum!

You'll find that after stacking in autostakkert , you will still need to apply wavelets, RG6 is good, I find Astra Image 4 has some good wavelets (and other processing tools) also...

Just a thought, if you were to take 300 indivual videos of jupiter, process each video to get 300 processed images, and then stack all of those, would you be able to increase detail? like I said, I'm relatively new, so any other tips or recommendations would be appreciated.

Yes and no.. if you just stack them, than you'll blur out the detail die to the planets very fast rotation..... so you'll end up with motion blur.... BUT.... you can use WinJUPOS, it has a DE-ROTATION feature that works very well to do exactly that, stack multiple stacks, and get more detail and less noise (higher SnR) in the final result.

      Hi guys
      Can anyone identify which control box this is? Is it focusmaster? And does it run off robofocus driver in Indi lib as I cannot get a successful connection (in indi within ekos) 
      I bought a robofocus motor with this control box second hand. 
      I have faith with seller that hardware works as should. 
      I've tried other cables and USB ports too. The software (k stars) I use does do port search when connecting equipment.. 
       
      Any help appreciated 
      Wayne

      I'm currently on my annual leave in Italy and the sky has been clear all day with no air turbulence.
      The telescope is out - of course - and I managed a session before dinner.
      I thought about sharing some photos taken with my phone and a couple of sketches.

      Jupiter imaged on 17 August 2019 using a C8 SCT, Skyris 618C at f33.

      Hello All,
      Sharing with you my best images of Jupiter and Saturn for this year.
      I haven't had the luck of a High Pressure system with no wind speed yet, but on the 17th it was as close as I had for planetary this Jupiter/Saturn season.
      Not my best images of the gas giants ever but ok IMO.
      I'm happy to see that the GRS seems to be repairing itself, last time I imaged Jupiter, the border around the GRS looked like it was breaking up so perhaps it'll be around long enough for my kids to see in the eyepiece.
      Captured at f33. Images consist of  the best 15% frames from 13x60sec @ 60fps for Jupiter and 13x120s @ 30fps for Saturn, derotated in WinJupos.
      Clear Skies,
      MG
