Quote:For most of the night, I viewed through just the eyepiece as this view is the best focus I get.
Quote:So you were just using an eyepiece, not a telescope?That would not form a coherent image. Or do you meanjust the eyepiece w/o a barlow? This is an unclearstatement.
Quote:But after growing tired of waiting for this thing to 'pass in front' of Jupiter, I loaded up my 20mm lens (no magnification)
Quote:A 20mm eyepiece would not have "no magnification"; given a 700mm f.l. it would be 35x. Or do you mean no additional magnification from a barlow? Another unclear statement.
Quote:and again was able to see Jupiter, a couple moons, and this object flying between them heading towards the gas giant. (I love this binocular setting!)
Quote:What binocular setting? It's a telescope with a single eyepiece (no binoviewer). Yet another unclear statement.
Quote:For a time, this view gave me a good look at this thing moving through space & what made last night more spectacular than others... for the most part (past 2-3 nights) I have been viewing this thing approach Jupiter from behind, and this is cool, because it's as if I am in it's wake of debris and what not.
Quote:You cannot judge perspective at Jupiter's distance, since the parallax would be so small as to be essentially zero. Anyway, a telescope is only a single optical path unlike binoculars.
Quote:So as this thing got closer, I began seeing coloration changes (I've never gotten any color from my telescope or lenses before) and as I zeroed in behind the comet, I could see a prism start to form around the wake, and as it got further into my view, the prism turned into a full blown rainbow!
Quote:Chromatic aberration. Especially since the eyepieceis almost certainly a Huygens.
Quote:By moving your head back n forth you should see 'distance' between Jupiter and ring, and 'distance' between ring and comet (smudge).
Quote:Again, you can't judge perspective in a telescope. The "ring" & the "comet" are almost certainly internal reflections/ghost images in the eyepiece if they movewhen you move your head. A roof prism in the diagonalwould cause a bright "spike" to extend from Jupiter(or any bright star).
Quote:I need people to understand that what I'm asking of them is to view an object between Earth, and Jupiter, so the gas giant will most likely be out of focus.
Quote:If that's Oval BA, what was the dark dot to the east of the GRS a couple of nights ago??

Quote:there are a couple thread's where people mention seeing 'something' (& this is really why I began posting) but my suggestion(s) have all been pretty much shot down. Is this due to my certainty, being new to astronomy & the forums, because my telescope is inexpensive... why?either way... i can't wait fer 8:00 to roll around --wonderer
Quote:that's just it. I suggest moving your head because these 'objects' don't move but rather 'stay' in place as one changes their perspective of Jupiter... Jupiter / ring appears moving in background, while the objects 'stay' in place.
Quote:I pulled this post from the Double Shadow Transit Jupiter Sketch 10/31/10 thread, and I am pretty sure this 'dark dot' is what I am trying to refer everyone to, as I was also viewing this thing / dark dot to the left of the GRS in my scope.

I'd rather be driving my .
Quote: Please keep in mind that the much bigger chunks, hardly stay in a clean silhouette like above, and I have to fight tooth and nail, getting these objects 'centered' enough before I can began seeing the above image.Also, from day one (26th), this was not a 'bullet shot' from Earth. However, i did indeed witness it being sucked into the gravitational pull, and for a good 3-4 days, it more or less spiraled towards Jupiter in a counterclockwise spin. Plus, if you look at my rendering from the first day (ignore the "ring" though) you'll see how stretched out it appears, and has consistently gotten much smaller as it gets closer and closer.--stoked
