Hi, I created a photo album into which I put a couple of images of the RA section of the GEM I am building. The ruler is a 6-inch rule and the bearing is a...
I put a file in the files section showing the PE error of an LX200 mount, a Meade LXD 55 mount and a Takahashi NJP mount. They should all be at the same scale...
Bob, Is the LX-200 PE before or after PEC training? I found on my three different LX-200 mounts that the high frequency components of PE are at the same...
Randy, What do you determine load with. You mentioned before about so many foot-pounds to the East or something. I have a hard time balancing my GEM. When I...
Carey, They best way to balance a GEM is actually to remove the worm gears. . .I forget which mount you have, but my old AS-GT had the same issue you mention....
Bob, If you don't mind, I also uploaded a file of the PE of my mount into your directory. I think it would be a great idea to change the name of this directory...
Yikes. I guess that would help, but not something I would want to do every time I set up my mount; which between star parties and TDS is pretty often. I do...
I have posted a new M33 image at: http://aisig.sdaa.org/astroblogDetail.asp?imgID=848&UserID=103 Should I change the color balance or brighten it? Thanks, ...
I changed the name of the folder. In looking at your PE file I do not quite see a periodic error. Was the PEC off? What does it look like with it on? Bob ... ...
On that LX 200 mount it only had one general PE training. It looks like you can still see some PE. I am sure you are right about the LX200 and load. I have...
Bob, Yeah, that was the whole point of my making that plot, to send to the folks on the Losmandy group for advice. That was with PEC off. Turning it on does no...
I've noticed inconsistancy with Losmandy worms as well. . .I actually had to swap my DEC/RA worm gear because the performance on the RA gear that was factory...
Nice work Auggie! I really like this. I won't make suggestions about brightening, etc., since I don't know that much. But keep up the good work! Alice...
Auggie, Nice image - nice round stars. If you want to make the galaxy more visible but not completely blow out the stars, try using DDP (digital data...
I have added my PE measurement for a non-goto MI250. It's about 6.3 arcseconds peak-to-peak without training. This is a 15-minute DSLR exposure (10D, ISO100)...
I have added a plot from my MI-250. The worm and gear on an MI-250 are a matched set and cannot be interchanged. The worm is diamond- lapped to match the...
I just posted my latest periodic error measurements in the files section. I tried a slightly different way of mounting the motor and worm and got somewhat...
I have posted a picture of M98 on the AISIG site. There is a small line to the right of M98. What is it from? I can see it move in each of the frames. Bob...
Thank You I wonder why my program puts that asteroid at 22:16:48 and -26:36. Bob ... From: Bob Austin To: SDAA_AISIG@yahoogroups.com Sent: Sunday, December 11,...
Hey folks, Has anyone used one of these??? http://www.stellar-international.com/ Just curious. . .focusing is a bear, and is going to be even hard when in 2015...
I recently made one of these knife edge focusing aids for my Canon Rebel and it works faster and whole lot easier than any other method I've used. The only...
Brian, Good info. . .I actually got my hands on a Epsilon 180ED recently (a demo model) and the focuser is MASSIVE. Would you mind sharing how you made yours?...
Nice astrograph - you'll have fun with that! I've been using Wright Newtonian (F3.8) lately and the faster focal ratio really makes a difference. It's...
Brian, SSSssssooooooooo. . .I've just scoured the AISIG website. . .where are these photos!!! Let's see 'em! Stop teasing! I'm also excited about the fast F...
I haven't yet bothered to put them up there. Do you have a good mount for the Tak? I have one you can bolt it to if you let me stick my camera on it. :) ...
I'm using a Losmandy Titan. . .so if you've got an AP or a Paramount, you probably edge me out. . .What kind of camera are you using? -J _____ From:...
