Jupiter 10_October_2021

[kirkster501]

It won't  win any prizes but I am working hard at learning planetary.  Seeing was absolute pants so this is best 7% of about 80000 frames with C925 with x2 Powermate, ASI224MC and a ZWO ADC.  A lot of moving parts to sort out and I am trying to learn.  I think the seeing was too poor to be using the Powermate.

GRS visible to bottom right and a spot to the north of the equator.

If you haven't you should:

- check collimation

- set focus using the Jovian moons

- set exposure at 70% of histogram

- use WinJupos to derotate your video if the exposure is over 3 minutes. It seems that you image is over 10 minutes.

- use Registax for wavelet sharpening.

- I have basically same equipment and in average seeing I get (although I have an 11 degree latitude advantage. Jupiter must only be about 21 degrees above the horizon for you):

@kirkster501, that's about where I am with my setup. 

@lainev, WOW

you have some good colour in there

Thanks for the replies.  I don't think my collimation is off that much.  I got my ADC nearly there I think.

That's amazing what you did with it Neil!  I did lot of tweaking and playing but I never got it to that stage.  May I ask if you can have a go at the raw .png from Autostakkert please?  These are three separate best 7% runs with the aforementioned rig.

The more you image Jupiter the better you'll get.

One night everything will fall into place. 

I always try to not worry about all the other excellent images on here, though I do like seeing them, and concentrate on my own game.👍

That's my thoughts too.  You have got to start somewhere.

I think there is a lot more data in there than I am able to get out with my skill level.  The .ser videos look much better than the output from AS3!  There is something suboptimal I am doing in processing.

[ItsmeMaw]

Ha! I'm still doing single images!😁

[lainev]

It looks like your focus may be off. Try focusing on a star that is 10 to 20 deg above Jupiter in elevation. Here is my go at processing your file. I did some rgb balance and some pretty heavy wavelet processing in Registax. How long was each capture?

 

[lainev]

I also noticed that you might not have your ADC adjusted all of the way. Registax RGB Align had to adjust your image these amounts: redX +1, redY -1, blueX  -2, blueY +1.

[kirkster501]

Thanks Iainev, it looks better!  I'll try that focus method with a bhat mask.  Or even on one of the Jovian moons.

Remember that a mask is only useful on stars ... not moons. Moons are not point sources. Some people say that you should not use a star and use Jupiter's moons but Jupiter so close to your horizon you might do better using a star. For me Jupiter is 30 deg above the horizon so I use the moons. Just thoughts.

same result as lainev

Just had a try using Registax 6 on your first image.  Your ADC Is certainly not helping.  

If you open the RGB Align tool and click estimate it will show you how far off you are.

 

Need to adjust each of setting manually before using any wavelet settings.

and click Auto Balance in the RGB align Tool panel as well.

 

I then used these simple wavelet settings no need to use more than the first two layers according to the guy who wrote Registax 6

 

 

 

It gave a much clearer image but still not perfect.

 

A few tweaks in PS will help.

Fabulous guys, many thanks.  First ever run out with the ADC.  It definitely looked better on the live view in Firecapture with the small ADC tweaks I had made - it removed a lot of the red and blue fringing.  I need to practise more.

Great start. 80,000 frames! How long was the video? With your 'scope and the x2 Barlow, any longer than a couple of minutes of video and you are going to get blur from Jupiter's fast rotation.  Remember, Jupiter rotates in a little over 9 hours & 55 minutes. It really whips round! Keep your captures short, one to two minutes for your focal length. You can always stack multiple stacks and de-rotate them in WinJUPOS (as Iainev said above).

Good luck with your next session. Jupiter is starting to climb a little higher each year now, so as in the old D'ream song; 'Things Can Only Get Better. Ooh I  should have saved that one for The Infinite Monkey Cage! 😁
