I took the PST out in the back yard a little while ago, to check the sun before it got too low and dipped behind the neighbor's trees. Well, whatdya know! A group of 3 little prominences on the limb. A spike, a broad feather, and a thin tendril. All three slowly morphed for the fifteen minutes I watched them. My best views were with a 16mm Erfle and 12mm Konig, no Barlow. No obvious active regions were noticed on the solar disk itself.
Chuck, I was about to set up the clubs PST this evening because for the first time in weeks it is clear skies. I decided not to after visiting the SOHO site which showed the same old image that we have seen for the past year. Glad to hear that you made the effort and it turned out good. I might have to try this tomorrow morning if it is still clear.

Did anyone else see the Titan shadow transit last night. I set up my 8" Celestron Ultima about 9:30 PM. I couldn't see it at the beginning around 9:40-10:00 PM, but it was easily visible at 320X and 400X by 10:30 PM and I observed it until about 11:00 PM. It was barely visible at 160x, but very easy at 320X. The shadow was just above the rings.
What! I was looking at Saturn around 10:15 just to see how the rings looked. I didn't even know Titan was transiting. I would have payed more attention to Saturn. DOH! On a side note, I did see Io and Ganymede's shadows on Jupiter at 5 this morning. ++++++++++++++++++ Troy Davidson On Tue, Jun 16, 2009 at 8:52 AM, Don J. Colton<djcolton@piol.com> wrote:

Troy, I saw the shadows of reyelid and leyelid at 5:00 AM this morning. Some of us must be more dedicated than others.

The sad part is it took me a few seconds to get that. I was thinking real hard what the heck reyelid and leyelid was. I guess that's what I get for waking up so early. ;) hehehe ++++++++++++++++++ Troy Davidson On Tue, Jun 16, 2009 at 10:22 AM, Rodger C. Fry<rcfry@comcast.net> wrote:

Troy, That was my intent. I'll cut you some slack because you were up at the crack of dawn and I was being a lazy slug.

Hi Don I watched the transit also last night w/ a CGE14 and 10mm Radian, 8/10 in 21 mph breeze at the summit, about 1am HST it just became too cool and windy so we all left aloha Rob
Chuck,Is there a way to hook up a H-Alpha to the 80mm for sun observation that doesn't cost $2500? Jim
Jim, I just don't know. I doubt that you could set up the 80mm or 100mm ED scopes for less money than the PST, which is why I went that route. Rob or Kurt, or others on this list more familiar with the current crop of commercial products could probably tell you what can be had, and for how much. The cheapest way, of course, is to borrow the SLAS H-a setup. One of these days I still want to build an old-fashioned spectrohelioscope, using a small refractor and diffraction grating. See promineces the way amateurs did back in the '50's and '60's. Jack Newton published a simple one in S&T back in those days that I will probably copy fairly closely. Another project for the retirement bucket, lol. On Tue, Jun 16, 2009 at 6:14 PM, jim Gibson <jimgibson0@gmail.com> wrote:

Chuck is right about the cost, a PST is the least expensive. Most on the market require a long focal length, the one the belongs to SLAS requires a f30 scope. Lumicon sells one, and I kenw someone who used it with a 6" f10 refractor, but it does not perform as well as the PST.
Rodger Butz researched some alternatives but found nothing better than the PST or Day Star. The clubs H-alpha is going to be mainly used on the Andy out at SPOC. Jim, I just don't know. I doubt that you could set up the 80mm or 100mm
