Is this is a bad time to see Jupiter noting I'm observing in the UK?

some other factors:experience helps. Elevation of target? Have you collimated your scope? What were your magnifications? I think it helps to learn the terminology for the different zones. Sometimes you don't notice a detail because you didn't know to look. Check out this site about observing Jupiter http://www.britastro...piter/guide.htm and http://jupiter.cstoneind.com/

Your scope under good conditions is capable of some sharp details here but as you kno, in pastel subtle intensities. Still you ought to see the gamut of surface phenomena, festoons, ovals, knots notches, barges , red spot into., rifts, gaps, - its all within reach. But, u need the seeing to allow it to happen. A little advice: blow a fan on the scope for an hour before observing - helps it stabilize quicker.
You have a great scope.

I observe Jupiter from North Manchester using a "standard" C8 XLT.
I say "standard" because it has two vent holes in the back and an active cooling fan - which I keep running all the time - it makes a massive difference.
I also use a TV 8-24 zoom (which is excellent) and find that collimating at the 8mm setting gives good results.
Jupiter is still showing a lot of detail - the wake behind the GRS can still be seen, last night I was watching a white oval in the SEB and saw a blue festoon coming off the NEB.
A few little tricks that may help...
1. Cool the scope to within an inch of it's life.
2. Collimate the scope to within half an inch of it's life.
3. Try viewing at dusk when the air is steadier and contrast is better.
4. The 12mm setting on your zoom will give the best results.

I'll check collimation at a higher mag to see if that helps.

I have no affiliation with this dealer but I know what a difference active cooling makes.

I do want to say- even in the dead of winter there are those nice nights - there's just more of them generally in summer. For all that, my message being: hang in there !!

By 8:30pm the view had deteriorated - Jupiter was lower and the sky was dark, views were mushy and no real detail could be seen.
Do try observing in twilight - it helps
