  1. To be honest wasn't going to bother going out but the postman delivered my new Svbony ir 685 filter from China & would you believe it the sky cleared a little!

    Just had a couple of 2min vids one with 3x barlow thre other with 2.25 barlow with normal setup. Seeing wasn't great but the IR pulls out a little more. Didn't bother with colour as it was awful. Did manage a quick compare with my 850 IR & was impressed how much more comes through with 685. Already looking forward to the next opposition.

    These look fine to me. Nice and soft with detail. I'm wondering how well you nailed focus on the colour one though

    Appreciate the comment 👍

    You could be right my eyes aren't great at achieving accurate focus, although I did soften the image quite a bit in image analyser.

    I really love the help you guys provide many thanks

    Honestly that's been one of my biggest struggles recently. For the final version of my Jupiter image from 1 Dec, I tried something that I picked up from one of Damian Peach's Patreon tutorials, which was to layer a blurred version on top of the fully sharpened version in Affinity Photo (Damian uses Photoshop, but the principle is the same), then use the opacity slider to blend the two to taste. I then used some regional sharpening to bring back the detail in selected parts of the image, e.g. the northern polar region, whilst leaving the equatorial regions softer. This approach seemed to strike that balance between detail and smoothness that I'd been stuggling to obtain.

    Interesting....

    Blending one over the other that actually makes perfect sense.

    Forgive my lack of knowledge but how do you do regional sharpening? Is it a case of selecting an area in gimp/PS & just adjusting that particular part of the image?

  4. Thanks again for your advice Kon.

    Your last couple of images showed good detail but we're also processed softly enough to show the gas giant as just that. Just wondered what tools you & Geof used to get the balance between detail & soft appearance?

    Really appreciate all the feedback given by all on here, it's so helpful in trying to improve the end result 👍

    The LD is in Winjupos under the derotation window. It might help but also consider Geof's comment on having enough data for the limb.

    Thanks Kon I'll have a look at that when I get home 👍

    I use pipp, autostakkert, registax, image analyser & PS to process.

    I see ones talking about fourier transform &
    deconvolution which mean absolutely nothing to me are these worth playing with?

    I presume they are on AstroSurface a program I'm new to.

    They’re both excellent images.

    As Kostas suggests, adjusting the LD value might help, but I’m also wondering whether there was a bit of time gap between some of the captures meaning a lack detail in that region when derotating in WinJupos.

    Thanks Geof

    I had 3 two minute avis timed at 8.34 to 8.40 so I'm probably thinking it was down to me not measuring the images exactly the same 🤦

    Thanks for the feedback 👍

    Excellent images. Lovely details on both. Your colour one has a reddish hue around the whites, you might need to adjust the red (and at the same time the green) to neutralise it.

    To remove the left limb artifact you can reduce the LD to 0.6-0.8. That should help.

    Thanks Kon appreciate your comments, I have to be honest not sure what you mean by LD to 0.6-0.8, what program is that on? 🫣

  8. As usual the seeing wasn't great down here but you just have to have a go, its addictive. Not in the same ball park as Geofs but I love to see the details coming through on his 👍

    I had some trouble with winjup aligning the colour as you can see from the left limb having a shadow, not sure I'm using correctly.

  9. Thats a tough one Geof I love both images

    I can see what you mean its softer than your original, I like the slightly warmer colour in the second but if I'm honest I prefer your original (probably says more about my sharpening methods 😉) I just find it more pleasing on the eye

  10. Thanks Geof

    I've always used sharpcap since I can remember & it's been nice to use, but recently I seem to be getting blown out areas in the white bands of Jupiter even though my histogram is only around 65%- green/red & blue are all around that mark but the luminance seems to be over cooked which confuses me, but to be fair it doesn't take much to confuse me these days 🥴

    I used FireCapture with roughly the same histogram & it wasn't blown out 🫣

    Looks a bit reddish on my screen. 

    Yes you are right 🤦‍♂️ On my laptop screen it didn't look to bad but on my mobile it looked extremely red! I've tried to lower the red a little so hopefully it looks a little more natural.

    Appreciate the feedback though 👍

  12. Finally got round to processing some colour images from the 6th. Seeing wasn't great but did get some detail coming through. I was having some real trouble with sharpcap blowing out the white areas even though the histogram was only at 60% so one is with sharpcap & the other with firecapture. No matter what I do can't seem to get them with the same colour!
