Jupiter through 80mm

O.K . this is not up to league of some of the other fantastic Jupiter shots posted so far , but considering Jupiter was only 20degs up in the sky glow of Brisbane and it was taken through my new little 80mm f7.5 ED refractor , I am pretty happy so far.
Wanted to get some at over head but the clouds rolled in around 1.00am , bugger.
The scopes prime purpose was to be a wide field lens piggy backed on my Newt and a Grab and Go scope but it's views of the planets are impressive. I just have to master the ToUcam and processing now.
I really pushed the limits of an 80mm scope and used my 4X TV Power Mate giving 2400mm focal length.
The visual views with the PM and 12.5 mm Orthoscopic were crisp and clear at.
Can't wait to get my Newt up and running again and give it a try on the gas giants and Mars latter on in the year.

P.S. thanks Graeme for your input at processing the image for me.
Can't wait to see what you do with the Raw file I sent you.

That is a sensational image. You must bevery happy with this scope

Very very nice Mark, can't wait to see the images through your big newt.

Very nice Mark. Quite a lot of detail present there.

Great work for an 80mm!
I have a ST80 and I get terrible cromatic aberation. That ED of yours looks nice.

Yep ,I would love to be able to afford a 8 or 10" TMB triplet Ed refractor but than I could buy a house for one of those monsters.

Ahhh , dream on .

Robby how does it perform at low power wide view though.

Nice image Mark.

Mark,
The ST80 is a nice wide field star/neb scope, but forget it on Moon & planets. I manily use it as a guide scope.
I reckon it's pretty good value for US$100. Got it 2nd hand off Astromart.
Still on the SP mount, it's a great 2nd scope when showing people the sky. At low power it's blows first timers away! Especially on open clusters & the like.
Cheers

That's a pretty picture mhodson. That celestron ed really is a nice little scope isn't it.

That's incredible for an 80mm scope. If you asked me what it was taken with I would have said 8-10 inch SCT.

Colour is a little off due to altitude and chromatic aberrations at such a high magnification , but I was just haven some fun and wanted to see just what it would do.
A ToUcam is equivalent to about a 4-5 mm eyepiece in a 4x powermate in a 600mm FL scope ---way over the limits , like 500x visual .
I think if you serious about a good planetary refractor one of the 100mm Synta Orions would turn out some nice results and then there is the reported 5" units coming as well , that would be sweet.
There is just something about the contrast of an unobstructed telescope that has kept refractors alive with the onslaught of the Dob and SC brigade .
I think even though I love my planetary Newtonian I will always have a refractor in my arsenal , though it will be of ED quality or above from now on.
Thanx for the comments guys.

Mark,
nice image, and for a wee 80mm even sweeter.
If the focus was spot on, and I have no reason to doubt this, then the raw could prove very interesting. Be sure to share it with us.
I had (along with an observing friend) my 80mm refractor out the other night, doing doubles in Orion. We both had 80mm refractors, and it was fun to bust a few of these tighter doubles.
I will try Jupiter with mine, but it is hard when the bigger scopes seem to say "Use Me".
