Quote:Thanks again for the kind comments!Paul, I'm sure hoping to grab the Polar Vortex if at all possible - I believe the dark "border" to the NPZ is "real" but as to whether anything inside the "Hex" is or not I cannot say.....but this is half the fun of our efforts as AA'ers imo - allways trying to push the boundaries! Quote:ZW Optics should pay you. What a great publicity for this what seems like a great camera. Well, Sam did give me 2 free cameras, so I really can't complain.....and it was a buzz to be so involved with Sam, Torsten & Emil in getting the camera "out-there" with such a great program as FireCapture: I looked upon my role as the "whip-hand" - Sam did his share of pleading for mercy as I kept harassing him to improve this or that etc! Indeed that was a real privilege.....not sure if I said this before but it was a real "leap of faith" to relinquish using my Flea3 and the first time I was at Tennant Creek for Jupiter I was trying to compare each and jumping back & forth - the second time I was up there I made the decision to go with the ASI120MM solely and I was rewarded with some great images from then on.....that when I'd thought that this year in Oz was going to be very poor for Jove's apparition! Paul & Glenn - I ended up rushing the last process in all the most important stages, I suspect the Encke isn't so kindly dealt with because of this and/or maybe WinJupos isn't so focused upon ring detail, because I did notice the rings didn't fit into the Alignment Frames the way the disk does.....the first image in this thread shows Encke much better imo...I might repro those stages when we're back home.Also, here's part of Prof. Agustin Sanchez-Lavega's email to me where he refers to his images back in 1991 at Pic du Midi:"Dear Darryl,Thanks a lot for this incredible image. As you mentioned probably is the first one of the hexagon taken by an amateur astronomer.One Saturn year ago (in 1991)! we took Saturn CCD images with the Pic-du-Midi Obs., 1 m telescope that marginally showed the hexagon and the Polar Spot then present. A paper was published in Science (attached)."Last night was a total cloud-out but we're ready if the opportunity arises; at the very least I'd like to test the stability of the primary mirror with my new locking mechanism, and how collimation and scope movement is affected.....it was such an easy thing to make and I suspect from "feeling" the primary adjuster knob that the mirror is quite "locked" in its' present position so hopefully no more movement.....also hope I've set the focal plane correctly!!! although it will be simple to re-adjust. Lastly here's the link to S&T's online "sky at a glance" for those interested.....http://www.skyandtelescope.com/observing/ataglance?pos=left

"Normal" people worry me! - If you want to think "outside the square" you really need to get out of your box! A kleptomaniacal plethora of gear: Custom-cooled (my designs) C11&14, Orion Optics (UK) VX16 16" F4 newt waiting for obs, ED127 triplet, NEQ6Pro, HEQ5Pro, ancient AstroOptics EQ mount super-customised with microsteppers, goto etc, ASI120MM, ASI120MC, Flea3 (retired - accepting offers!) Toucam 840k, modded Canon 50d + F4L etc,etc & lots of other homebrew equipment.....

Quote:Thanks Mike, the interesting thing is that when one pauses the HST animation the hexagon isn't immediately obvious. Only when the animation is running or when viewing a polar projection does the hexagon "jump out" at the viewer. Pete
Quote:Looking at the blog again, it's evident to me that other parts of Saturn's cloud structure have flat segments as well. Not just the north pole. I suspect that this has already been noted and studied by the Cassini folks.JimC

Quote:Thanks for your prompt and detailed reply. I do collimate my 12" LX200GPS using the imaging configuration and camera (2.5x PowerMate, Flea3). Like you suggest I monitor the laptop display as I adjust the collimation knobs. I usually must have the star out of focus by a considerable amount to make it large enough to see the image from the small three step ladder that I use to reach the collimation knobs. My scope is on wheeley bars and a large field tripod. Using this technique I am never quite certain that I have the out of focus star image centered quite properly. Is the collimation image that you posted the actual size that you utilize to collimate? Do you have examples showing a "good" collimation that you could post? When you talk about an "on the fly" capture and processing of the collimation image, do you use Registax to do the processing? Will Registax align the collimation images correctly? How many collimation images do you stack? Do you do any type of post-stacking processing?Thanks for your help,George Hall
