Just a White Disc!
Posted 15 January 2004 - 01:17 AM
Hi Guys and Gals,
I was trying to get some nice views of jupiter the other night, however i am still just seeing a white disc shape, and its moons.
I have a Celestron 114GT (4.5" Newt), (and collimated it that evening, before going outside, and double checking after it cooled). as well as the eyepiece kit with the Six Coloured Eyepiece Filters Yellow#12, Orange#21, Red#25, Light Green#56, Green#58A, and Blue#80A, what do you suggest i use to be able to atleast see the belts of Jupiter? i tried the Red#25 with the 15mm-Barlowed, and from what i could tell i was getting a red disk, i didnt fool around with it too much longer, i had to come in, it was -30 celcius, and my scope was outside prior to using it for a good hour. I have Heavy Light pollution i can see about up to Mag +2 only. Any ideas on what i can do to be able to atleast see a cloud belt?

only say I can see at least 2 cloud belts on Jupiter with my 114GT. I'm sure you will get some good advice here. Don't give up.

for fear of frostbite, perhaps you should wait until it's a little warmer out....

Depending on where you live, you may also be getting interference from the jet stream. The jet stream tends to smear images. Stars don't twinkle, so the seeing appears to be good, but the images will be smeared and lacking detail. It was once so bad where I live that I couldn't tell Saturn had rings! Check http://www.cleardarksky.com for a clear sky clock that will give transparency (not usually a problem with planets), darkness (also not a problem) and seeing conditions for your area. Also, you can do a Google or other search for jet stream forcasts and see if you are under the jet stream.

Usually any kind of scope should show at least the two dark (equatorial) belts.
Seeing more details requires a little practice and a good scope, but you should see at least that.

I did manage to see Saturn and its rings. Saturn is very small (even at with a 10mm lense) but you can see its rings.
