Quote:David, what about Enke's division, ever seen it in your 16 incher?

Quote:I thought I observed Enke once in a 6" Mak. But after some research and a lengthy thread discussing it, I determined it was not very likely observed. Highly improbable, in fact. Enke minimum, however, will suffice.
Quote: the IAU compounding the silliness by calling an impossibly fine line even nearer Ring A’s outer edge the Keeler.
Quote:Saturn’s rings seemingly being particularly prone.
Quote:Attached is about the best view I ever had of Saturn.
Quote:I'm also intrigued by the bright spot in the temperate zone; how "visible" was it? Could you definitely see its rotation?
Encke div: I spout off about this IAU thing at any opportunity it’s had me riled for years! I got the impression those that might have had some influence just seemed to roll over and accept it – speaking to, among others, upper-level BAA people back then.
Quote:though for myself I like your term "draftsmanship"!
Quote:[around; would love to know more about your technique.
Quote:So these oculars deliberately showing chromatic aberration work to cancel out atmospheric dispersion colors on things particularly like Galilean moons at high power and such? Amazing .
Could you explain it a little further? Is this a standard tool or method or one you developed on your own. Its the first Im hearing of it . Particularly in Connecticut in winter, dispersion can be very degrading to the image indeed. It'd be a fine thing if I had such a thing to counter its effects.

the accurate measurement of intensity and positions over the realistic rendering of the planet.
Quote:I too love the personal connection I feel with the object I am drawing and whilst imagers are able to record finer details with less uncertainty, I think that it is a colder and less enjoyable pursuit, obviously others disagree, and that is what makes it all so interesting.
