Answer to my own question: On second thought, I bet they are doubling photos, showing us two of each image so that the movie lasts longer. I saw in another odd blip that it was there for two frames. So there is noise on a frame, the frame is shown twice, and the noise seems to persist. -- Joe

This editorial was indeed very poorly written, so much so that I couldn't stand to finish it. I will however say that I think that the landing on Titan is a tremendous acheavement and worth every penny. Also I believe that society should pay for such endeavors as the mere aquisition of knowledge bennifits all of human kind. So what if most people don't appreciate such things? If human kind had always followed what the masses would have us do (in terms of scientific learning) we'd still be in the dark ages.

Joe,
Hhhhmmmmmmm, what if it were a frog and just jumped off between frames. Could have!? Jim
Joe Bauman <bau@desnews.com> wrote: Could well be. But I'm a little puzzled why some electronic noise would persist for more than one frame. In frames 126 and 127 we see a little light "frog" show up on a rock, then disappear. It's an angled rock about halfway up the frame and about a quarter of the way in from the left. There are other examples, but that's an interesting one. -- Thanks, Joe

Debbie, if he was using it with a telescope that would fit on a Losmandy mount, it was probably too-small, or marginal. That parallels my experience. It's a great product, but not really suitable for small apertures. Even 10" is pushing the small side for the Easy-Guider. Many (most, it seems) objects just don't have a bright enough guide star at the right radial distance from the center of the field, this can be frustrating and you can't always compose the shot just the way you want it as a result. No competent reflecting telescope maker would design for 100% illumination 1" off-axis unless it was a dedicated imaging system like a Schmidt camera or similar, and not many amateurs can afford a 12" refractor (except for Al George, who has a 15"!)
One a large scope, it would work much better.
That said, the principle of the off-axis guider is excellent: Guide with the same optical train as the one you're imaging with, and you eliminate differential flexure as a possible source of trouble. The bigger the image scale, the greater this problem can be.
I use a separate guidescope on my small set-up.

I guy e-mailed me from the Losmandy yahoo group the other day and he had trouble using it and sent it back. I'm not considering that option anymore. I'm now looking into a guidescope on a dual scope platform right now. Thanks for the feedback.

Place yourself along the path indicated below tomorrow between 2041 and 2042 MST and you've got a pretty good chance of seeing ISS pass in front of the Moon.
Looks like Flying J out by SPOC will be a good place to observe from.
Patrick
A - travel distance (kilometers) and direction B - date C - time D - elevation angle of the ISS E - azimuth angle of the ISS ( + is East from North; - is W from N) F - range (kilometers) G - latitude for observing the transit H - longitude I - elevation above Mean Sea Level (meters) J - how far (kilometers) can I be from the centerline?
For other than solar transits: K - lunar transits: is space station sunlit? planetary encounters: 1=Mercury; 2=Venus; 4=Mars; 5=Jupiter; 6=Saturn L - sun elevation angle M - sun/moon or sun/planet separation angle

Kim, like you I was annoyed and puzzled at the slow rate that information was being made available at the time of the landing. But ESA is a tiny organization compared to NASA, with a proportionally smaller budget, and is subservient to more than one governement which I'm sure is a bureaucratic nightmare. With a comparatively smaller staff, "first things first" was probably the order of the day at ESA. It's a shame that any dollars going to research have to be spent on any PR at all, it's just a drain on the real work of the institution. If just the burning desire to know the truth isn't enough, if we as a species are dependant on "wow" factors and effective marketing in order to fund scientific research, then we don't deserve to learn of faraway new worlds in the first place. We're just delaying the inevitable end. "Rome" will fall again, for pretty much the same reasons.

Was part of the delay and slow release a technical issue. The probe had to transmit to the orbiter which relayed the data to earth. And the orbiter was on the other side of the planet?
