Hi Roger, is it a colour cam, if so do you use a ADC? What are you using to stack, regisax does a RGB align as it looks like you blue channel is out of alignment
Thank you….it’s an asi120mc camera….no ADC. I did the wavelets and RGB align in Registax
Cheers

Nice Image!

Good Afternoon
....still having issues trying to get rid of the blue fringing. I have an older version of Photoshop elements but no luck with it in this. Is there another way I could try?
Thank you
Roger

What date and time did you take the picture from your location? Sometimes Ganymede and Callisto can be quite a way from the planet even when their shadows are crossing the planet.
Thank you....I did try to check on Stellarium but computer was acting up,,,,jere is a readout though01_30_52.CameraSettings.txt

Hello
I can make out a shadow on this one but where is the moon?
-
Thanks again Jim. Very interesting information. This capture was 79.852 seconds which does not seem too long (?)

Roger I am by far no expert in imaging never mind planetary imaging so take what I offer with a large healthy dose of suspicion! Did you have any filters in the image train, UV blocking for example to reduce blue bloating and help improve focus? I'm also wondering if rather than an image capture problem it arose in processing. It almost looks like the stacking has tried to align images that are perhaps at the limit of being "alignable". Could you try increasing the reject rate and concentrate on the best of the data capture. Hopefully somebody with more expertise (and skill) will come and offer better advice.
Jim
Thank you Jim
I am using an asi 120 mc camera which I understand has a built in IR cut filter. I will certainly try a smaller stack percentage as you suggest.
Cheers

Good Morning
This is a from a stack of 70 percent of 6000 frames. Seem to be getting a blue fringe on the right edge...Is there a fix for this?
Thanks for looking
Cheers

Cool! I just started my own first wobbly steps with planetary imaging, I got a moon shadow on Jupiter's disk but no moon.
It's so different from deep-sky work, in particular the total neglect of some things that I obsess over for DSOs. Not easier, just different. Polar alignment? "Squint over top of scope, yeah, that looks about right". Autoguiding? "Punch DEC button on hand controller from time to time". Unattended automation? "Eh, I've been out here for an hour and have a few gig of video, think I'll hit the hay."
It's kind of fun to be a total noob again. Sort of like when I was 40 and an expert skier (Senior Ski Patroller, yada yada) and decided to try snowboarding. "Well (WHAM) I guess that (WHAM! WHAM!) I am learning at least a little bit of (WHAM) humility here."This stuff does keep a person humble….so much to learn but I enjoy the occasional Eureka moments. A good sense of humour such as yours certainly helps

Hi Folks
I tried a few captures this morning….was quite a bit of dew. I did get the asi120mc up to 75 fos on som captures. Used a 9.25sct with a 2x barlow. I am finding that using the zoom in Sharpcap helps me with focussing. I was pleased to see a moon in there.
Thanks for looking
Cheers

Great images……. How many fps will the asi462mc do?

It's not bad, but a C9.25 should be capable of more under the right conditions. If you tell us what capture program you were using (Sharpcap?) and copy the camera setting file here we might have some tips.
The image looks like the focus could be better. With Jupiter you can use the moons as focusing aids.
Thank you for your inputs....I can't wait to try focussing on the moons....I did send a data sheet
Cheers

Thank you so much Ross. I do have an older Celestron motorized focusser....it's mounted to the regular focusser with one screw...I will have to hook that up more for these. I do understand what you meant by focussing on Jupiter's moons.....If I increase the field of view and bump up exposure a bit ....focus then set the exp and smaller ROI....can't wait to try that. I will use that motor focusser to better advantage. Also I was not aware that my asi 120 mc could get more than the 45fps or so I was getting;.....thank you for that input also
Cheers

Thank you....yes I was using Sharpcap. I will try using the moon for focus (will have to increase exposure for that?) Here is the data sheet

Hi again
I am still trying to edit some Jupiters from the other night....I did some with a 2x barlow but then tried without hoping I could brighten it up. Used a 9.25 sct and asi12o mc camera
Thanks for looking

Great picture, and more importantly great progress! Really getting some good detail and it’s always nice to get the GRS in. Is there a reason you’re going for linked wavelets? They have their use, but I’ve often found that using the ‘sharpen’ and ‘denoise’ buttons mainly on layer 1 (crank the slider all the way), with minor increases to layers 2 and 6 get me 99% of the way there and are much easier to use as someone just starting out. Increasing that layer 1 denoise button a couple times can do wonders to cleaning up my images. Keep it up!
Ross
Wow....I tried that on layers 1, 2 and 6 as you kindly suggested....it sure narrows things down for me and I will be using that method as I get more captures.
I think it was 45 fps and did get 5000 frames. Thank you again.

Thanks Ross….I have more avis to process and will certainly try those wavelet setting

You have captured the giant. Okay we can all agree that it is not going to win an APOD, but you should be rightly proud of that image.
Before we had probes into space and orbiter’s that could take close ups what you have there is just about what we had from the greatest scopes on Earth for the time.
You have banding and the GRS and mix of colours which look natural to me.
Do you want to add any detail about how this image came about, camera, scope etc.Marv
Thank you Marv
I used a 9.25 sct with a 2x Televue barlow and asi120mc camera. 25 percent of 5000 frames in Autostakkert. Still trying to get my head around the linked wavelets in Registax. Trying various settings to see what might work better. I thought my collimation was all right but will have to check that again next time out. Also I did a few captures without the barlow which seemed to be brighter

Hi Folks
I tried some imaging this morning....Jupiter appeared kind of dim beside the moon but did a few captures at various settings
Thanks for looking

Thank you all for your generous suggestions. I appreciate very much your sharing with me examples of how Jupiter should look when imaging and also the settings data. The weather has not been cooperating lately but hopefully soon I can do some more imaging with these inputs in mind

Hi,
What was the altitude of Jupiter? What is your focusing procedure?
Maybe you could show a single frame of one of your top 25%
CS Patrick
Thank you. I think it was about 40 degrees. I was using a Crayford style focusser. I do have a motorized one but was not set up at the time. Here is a frame...
defringing?

Thank you…..Jupiter seemed quite high up to me…..but perhaps that’s the next bit of kit
