Mono Jupiter from London

G and B were awful, so this is through R filter.

I'm wondering if I need to refocus between filters, or if B and G, they were big smudges! Or if it's just futile from the city, I'm not sure. Happy with R anyway Old Juve is such a beaut!

Nice image, despite the difficulties. Seeing affects shorter wavelengths much more than longer ones. An IR-pass filter is sometimes used to reduce blurring further

Some detail in there but I would try a 25% stack. Still plenty to keep noise under control after sharpening in R6 or whatever you use but will cut out some of the poorer quality pics.

Despite the only too familiar trials and tribulations  you have managed to record a lovely detailed image. Well nailed.

Blue is nearly always inside (ie, less drawtube) R&G but for a lot of us the G % even more so the B has been very poor this year.

But a decent effort under what I suspect was poorish seeing   - you can try reducing the stack-size as suggested...in fact I'd go for 5% & 10% quality stacks: ie, the best 1000 or even 500 frames - it is a common misconception that "more is better" most of the time...the better frames WILL have less noise & more detail usually (unless they're all rotten!)

Don't take my word for it - test this out...after stacking these 2 different-sized stacks (preferably in AS!2) drop them into 2side-by-side Registax6's opened on you screen & apply similar wavelets & de-noising - as I said often the lesser sized but higher quality stack will win out!
