Nice shot Peter very nice, exceptional. Especially if it was just a "quickie". You must be very pleased with the results you've been achieving over the last week. First rate. Looks like another Iceinspacer heading for an image submission to the Aus Astro Mags. Well done.
I think I might hafta drag out my LPI and give it a go again. Certainly not achieving anything at the moment with the ToUcam.
It can be frustrating, but with the people here the frustrations disappear and we have a lot of fun. Life is too short to worry about "the small stuff". I know I have a long way to go, but with the excellent help I am receiving from Paul and people here, I am confident I can get a great deal from this. I hope I can get out tonight and see if the IR filter will give me that final bit of sharpness. Yeah and there is a bit of crud somewhere that shows up when I am setting up for the AVI, cant find it on the CCD cover or any of the Powermates etc, but because it shows up when the image is focused, it must be on or near the CCD, any ideas please.
Hi Peter nice image you are learning fast :-)) if the crud looks like donuts on the image then it may be a speck of dust, be carefull if it is on ther ccd chip, try gental blowing it may come off.
I was surprised to find out how small a piece of dust is needed to put a spot on the image. I kept finding a couple of spots coming out on my images yet couldn't see anything when I looked. I then got out a magnifying glass and checked, and sure enough there were two small spots of dust that "looked" pretty much transparent, but were enough to affect the image. Removed them and no problem, and they weren't transparent, just dark coloured (looked transparent on the dark chip).
One of the problems I found with the ToUcam was that when I removed the original lens and screwed in the adapter, the metal thread of the adapter shaved small pieces of plastic off the ToUcam thread which then deposited onto the CCD. This is a pain as after I remove the adapter and clean the CCD, I then have to be very careful rethreading the adapter as more bits of platic then come off. At Least with the LPI both threads are plastic so this shouldn't be as much of a problem
Very good Peter, looks like the master has now become the apprentice. Much better than anything I have ever taken. Good definition in the GRS and the festooning in the eq belt is very good, couple of nice white ovals as well.
Good stuff, keep the AVI, I will do some editing if you like. At least I can still do that. Keep up the good work.
Hell thats a nice image, I don't even see Jupiter in that detail when looking through the scope, closest thing I have seen is a fuzzy blob for the GRS and the bands.
That is a great shot! Lots of detail but it doesn't look overprocessed like most amateur shots tend to..

Thank you Tony! Nice to know that my cheap 8" Dob can compete with a pricey SCT for visual. When the GRS is up and the clouds are away I can see it clearly. The "eye" shape is very apparent.
Yes Robin, with a Toucam2. I had some crud on the ccd too so I was trying to dodge that. They seem to get dust or something similar very easy. I have a Lab light with 4x magnification and I still cant see what is on the CCD though. Maybe I need some younger eyes to look at it.
How long have you had the toUcam 2? I've been thinking seriously about getting one for some time now but it's always another EP or digital camera memory card takes precedence. Any big issues coming to terms imaging with them? I'm familiar with stacking,aligning etc.

ditto. on a good night viewing I can see the grs and more....
must be a 8" dob thing
Nice shot Peter. All the prominent details shown there were visible in my 12.5" at 240x on Friday night, albeit a little fainter in Jupiter's brightness.
Experience is key to seeing features on planets, and this comes from heaps of time at the eyepiece - the longer you look the more you will see. I used to have fleeting looks at a lot of objects during a night of observing, now I find myself targeting a few objects and spending more time with each. During this time I try different magnifications to see what I can tease out of an object. For instance I have had great views of the central structure in the Ghost of Jupiter (Planetary nebula in Hydra). In earlier years I had found this object with low power, acknowledged its bright disk and moved on. However lately I have been spending time with it and adding power makes the "CBS Eye" shape to its central structure stand out. I would suggest those with 12" dobbers and above (and there is quite a few around here) should spend some time with this and see what detail you can see with high power. Also, (hopefully not getting too far off topic) I would be keen to know if those with smaller scopes can see this central structure as well.
An interesting thing was that on Friday night the seeing was very variable, infact Jupiter cycled from a boiling blob to a super sharp image over the half an hour or so I observed it. It was sharp for periods of 2 to 5 seconds and was sharper than I had ever remembered. Not sure if this was an artifact of the image also being so bad that it gave an extreme reference image (for comparison), or whether there is something more physical in the turbulence that the steady air is extremely steady (doubtfull).
