    Excellent - particularly the detail on Ganymede !

    Thank you! I was surprised that it would resolve anything, but when compared with a simulated view, it does match up

    Very nice images. I quite like the animation from the 26/9 as it's really cool seeing, I presume, Io coming in and out Jupiter's shadow.

    Thank you! Odd one that: It's actually a stacking error that I missed when processing. the moon drifted outside the alignment boxes when I was batch stacking the videos, so there are about 3 frames when it's seem to almost vanish. I still have the raw stacks, so could redo it...maybe one day 🙂

  2. Last night I wrestled my C11 off the mount and put the refractor on, thus ending my Jupiter imaging for this season (unless an especially perfect evening presents itself). These are all with the C11 and a selection of cameras / x2 powermate, hence the differing image sizes

    This is my collected 'best of' from this year:

  3. It's been a while since I point a scope at the moon for anything other than a quick look. I finally demounted my C11 last night, after pursuing Jupiter for as many sessions as the recent weather has allowed. The FL of the C11 didn't easily allow a full disk image without a lot of mosaic panels

    107mm x 700mm 'frac, PlayerOne Mars II-C

    6 panel mosaic, 50% of 5000 per panel, AS!4 beta / Registax / ICE then pushed the colour a little in PixInsight. I'm a little rusty at this

    So it normalises to black 🤯. Is that for all %s? I won't be upgrading yet then....

    Apparently, it just the first stack and then it behaves - I've not tested that, I just unticked it

    So, I restacked with AS!4 then assembled it as per my usual method, as close to the same workflow as I could (not rigorously scientific!) :

    Old v New

    Humm...even without the normalisation, I'm happy to use it I think* 🙂

  5. Somewhat choppy seeing on the evening of 11/11 with quite wet air - par for the course in Lancashire! (insert the obligatory moan about the weather)

    C11 / x2 Powermate / PlayerOne Ceres-c (imx224) / iOptron CEM60

    Captured with Firecapture, 180sec per stack, 30 stacks. 5ms @ 200fps, 800x600 ROI. Batch sharpened and colour balanced in PixInsight then cleaned up the background and made the GIF in PS

    Single frame

    Wonderful picture, congratulations! There are some frames where Europa almost disappears, what happened? Did it go out of the camera's field?

    Thanks you and well spotted!

    When batch stacking, I try to put some points alone the moon paths. I suspect I missed a frame or 2 so the moon didn't stack. When I spotted it, I considered redoing the bad frames...

    That looks like a cracking lens - beautiful image. 🤩

    Cheers, its a heavy lump but very nice!

    Cracking image! Is that at full aperture?

    Cheers! Yes, wide open at f1.4. The corner stars we're slightly T shaped, but nothing horrible

    I was only reading a review of that lens this morning. What a belter!

    I'm not disappointed, that's for sure!
