Last night (Mar 20) we saw the shadows of Ganymede and Io transit Jupiter. Another moon was just on the limb and finely disappeared. Do you Yahoo!? Yahoo! Finance Tax Center - File online. File on time.
That's awesome, Jim! Makes me wish I could have been out Saturday night. But as it was, I was set up at the Wedge Friday night, but managed to get a nice Jupiter picture, which I will be posting in my gallery. Be4st wishes< Joe
Hi All, A quick report on my excursion to the Wedge Friday night. I drove around searching for Kim and the Grahns, but couldn't find them when I was looking. I did come across Kim's sister and her family and she thought they would be around somewhere. I looked again but couldn't find them. So I set up not far from his sister's family. Shortly afterward, Kim walked over -- he and his family and the Grahns had been camping in an area I had not checked. By then I had my 'scope up in Polar mode and it was too heavy to take down and move again, so I decided to stay there. But I walked over to their camp and I was able to meet some really nice folks. Back at my camp, my trouble was just beginning. A huge dark cloud mass obscured much of the sky, including the Big Dipper and Polaris, making it impossible for me to make my final checks. So I just went ahead and pretended I could see Polaris, and did the other alignments. It turned out that, because I had used a compass (propery offset) to set up, I was close to the correct setting. After the clouds cleared the night was glorious, with nice, steady viewing. But my main goal was to take photos, and I tried to get my Meade LPI system to track a start so I could make a long exposure. That was impossible. I succeeded in getting the LPI camer and a 26-mm lens to be parafocal to each other, but I couldn't get a star to show up that I could track with. I suspect the parafocus wasn't point on so the star images weren't sharp enough to show up. I will need to work on that some more. This took most of the night. But I managed to get a glimpse of M-51, which was extraordinary, and the stars around it were especially bright. Also the Orion Nebula was bright, early in the evening. I gave up on using the LPI as an autoguider and decided to take some Jupiter pictures with it. I didn't spend much time or effort on this, as the image began to blur and bobble around, I suspect because predawn high-level breezes were snorting through. But a couple were surprising to me, in the amount of detail they show. I have posted two of them to my gallery (see the link at the very bottom of this note). So the night was sort of a failure and sort of successful. Best wishes, Joe
PS: The Jupiter photos are on the second page of the album. Thanks, Joe
Joe I looked for your jupiter moon shot but didn't see it. I will look again in a bit. Dave Bennett I love the animation gif file you posted of the moons of Jupiter rotating around.

Great, that's it. Just wanted to show a couple of views. Thanks, Joe
Oops, I see what you were referring to -- I accidentally put the wrong date on them. It's March 20, Saturday morning. I've corrected that. Thanks! -- Joe
Nice color Joe. How long was your exposure and did you stack images? Jim Joe Bauman <bau@desnews.com> wrote: Oops, I see what you were referring to -- I accidentally put the wrong date on them.

Hi Jim, Each view is actually a series of pictures that were stacked automatically. I think the LPI (Meade's Lunar and Planetary Imager) was working around two minutes for some pictures, four or five for others. I can't let it work on any one view too long because Jupiter rotates swiftly and the clouds don't stay in the same position very long. I found that out when I tried to stack a couple of earlier views taken some time apart, and the result was a blurring of detail. This was through a barlow, which magnified the image and made it so that the details would be even more obviously moving over time. The way the LPI works is that you tell it what's the least acceptable image it can stack, and it goes at it, keeping track of how many photos meet the threshold you set. For example, you can say it should grab any view that is at least 85 percent as sharp as when you start the process, is how I understand it. I tried to get 50 or 60 good images, but usually did not as all sorts of things interfered. For example, seeing would suddenly turn so bad that no good images showed up for a while so I had to call it off for that picture in order to make sure clouds didn't move and blur the resulting view. Thanks, Joe
