Nice images Chris - the achro has done pretty well there. Conditions were pretty good on Thursday - I was out doing some sketching of Jupiter so interesting to compare with your image. What’s the GRB by the way? Great Red Blob? 😉

Haha didn't even notice that, well 'spotted' (sorry)... great red blob does also work though 😁 I used a Semi-Apo filter with the achromat which does help sharpen things up but was really fighting the seeing on Wednesday. Thursday as you say was much nicer and the live view of Jupiter was really nice with the 200p.

Were you using the ED102 to sketch? Feel free to post the sketch here for comparison if you get time.

@Chris I imaged Jupiter on Tuesday night (27th Sept), when conditions were quite favourable, here in SW Scotland.  I was also using the SW Evostar 120 achro, with a ZWO ASI224MC (no Barlow) and a UR/IR  cut filter and Wratten #8 yellow filter.  I can see that you had similar results to me, as in the two cloud bands turn from a brownish colour to a purplish one.

Here's two images from that evening, one the finished image and the other before much processing...

Critique is always welcome.

@Ian McCallum Nice before and after Ian  The irony, hey! using some kind of minus violet filter seeming to result in almost violet weather belts 🤔

@Chris Hope you don't mind, but, I've taken your image and done a bit of adjusting in DxO Photolab. Mainly around HSL to remove the violet from the frac.

Here's a before and after:

Here's another attempt at Jupiter, last week (with the Baader Contrast Booster).  I has tracking and alignment problems with the mount, which meant I lost several hours chasing my tail.  I did manage to get some images of Jupiter, but I couldn't quite get the focus right, using the new 2x BST Barlow..

Sorry I've only just found your reply! Don't mind at all, it's also made the Jovian moons stand out a bit more

Very nicely captured.
