I personally don't. I keep the tube covered with some dessicant inside. I'm just too afraid I will damage the coating if I try to clean it. You probably will...
For me, it's once every few years. I'm not an avid observer, and keep the scope openings covered, so the only real exposure to dirt the mirrors gets is when ...
For me it is about once every four years or so. I try to do a lot of preventative maintenance. Things like shower caps on the ends of the tubes to keep out...
Man-o-man be careful. Cleaning fluids and eyepieces don't get along well. It likes to wick into places it shouldn't go. Camera lens cleaning tissue used...
Hello all, I'm a new member. I've been using a 120mm refractor from Orion for about 2 years. I recently converted the EQ3 mount it came with to Go-To...

Tom I own an Orion XT10 with the computer locator. It is very easy to set up and use. A two star alignment and your done. Not to mention it is a beautiful...

Any Newtonian users tried (or built) a scope with a curved spider? If so, what is your evaluation? __________________________________ Do you Yahoo!? Send a...
I have an 8"f8 Newtonian built by Ed Grissom. It has his curved three vane spider. This telescope gives the best planetary views of any I have owned. Over on...
I have a 6" f/10 planetary scope designed by Steve Dodson. It has a single element curved spider, as well as an over-sized tube. I liked the views throug it...
I am overhauling my 8 inch f/6 dob that I ground the mirror for several years ago. The moving people were not too nice when they brought it up here and it...
I just bought a Celstron 4.5 Newtonian Reflector First Scope as a gift for my spouse. We can not figure this thing out. Neither of us have ever laid eyes on...
Andy has done a fine job making up some very informative on-line video tutorials. You might crank up the PC speaker a bit and go through some of them. ...
The best help you'll find is with a local astronomy club. You don't have to be a member. Just find one in your area and see if they do observing. Go out...
Theoretically yes, but what are you going to use to control the de-rotator? How will it know the correct de-rotation rate at any particular time? -Christopher...
Hi Christopher I dont know too much about the de-rotator, this is why I asked. I thought rotation would be of a consistant rate from horizon to horizon and...
(de)rotation rate will be different for different points in the sky. So unless it is under some kind of program control, it will not know what to do. If you...
Actually I'm looking to my next investment in a scope I like the light gathering power of the 22"-24" dob's or should I go for a 14" sct as I would like to use...
How about an unobstructed TMB 130mm APO refractor on a Vixen GP-DX or Losmandy GM-8 mount combined with a Finger Lakes CCD camera or a Nikon D70 or Canon 300D...
The only info in the manual is the assembly info and it was vague to say the least...but now that it is assembled we can't figure out how to use it. I tried...
i do have the instruction book but it gives very little and vague instructions. I will try the site you suggested. I am also looking to see if i can find a...
The attached image is my meager attempt to draw an equatorial mounted scope. To align finder with scope, you can even pick out a day time object far off....
