Hi Pierre and

mate , jupiter is 440 million KM's away and we look at it thru about 40km or atmosphere , and thats where seeing starts , we only get around 10 nights a year when seeing is as good as it can be , the rest of the time its either

cloudy or the seeing is carp , thats a fact of life living here on the Earth's surface .
Dont expect Hubble like images all the time , keep you magnifications at around 100 -120x ( an 8mm -10mm ) eyepiece with your scope . By the way what eyepieces do you have ?
I had one of the scopes that you now have and it gave really good views of jupiter at the 100x to 150x . Only good nights allow you to get to 200x + .
Take your time , train your eyes ( they are mussels ) and things will improve over time .

.
Use this time to view deep sky ? your scope is one of the best for this under 10 inches apateure , enjoy it mate .

.
Brian.

Whereas it was a very satisfying sight, I was a bit disappointed by the lack of contrast of the image. The focusing was sharp, and the image was very bright (too bright?), but colour bands were not really visible at all, the whole disc was a very bright yellowish colour, with barely any variations.
That was the case regardless of what EP I used, with or without barlow.
I hadn't cooled down the telescope for very long, but it was a warm night and inside temperature was not much more than outside...
I was wondering what would be the next stage to improve that ? I was plannign to buy a 5 or 6 mm TMB one of these days, but is there something lse that I could do before to improve this side of things?
