Hi, Has anybody shortened the extended bolt that holds the secondary? The scope came with a large weight on this extension but my scope doesn't need the weight...
... Thank you, ... Hi Maureen, This should be a pretty straightforward surgery. I assume you'll be removing the secondary holder from the spider first. I would...
I agree. If its not used then it may be removed. Be sure to remove or cover any mirror surfaces to protect them before doing any work inside the tube....
Maureen, When you shorten the bolt, do a few things: 1.Add a fender washer to the top of the secondary cell so the collimation screws press against a steel...
The other night while observing I spent half the evening using a hair dryer to remove Dew from my eyepiece, finderscope, and primary/sec mirrors. Nothing like...
1.Use a shroud. This more-or-less prevents dew on the primary. Also, store the telescope horizontally when not in use--don't leave it pointed up. 2.Cap your...
I too have a 15" truss dob, but have never quite had dew on the optics as bad as you describe. I would say that if the dew is THAT bad, then yes, it is...
Our son has a new Discovery 12.5 inch Truss telescope. He is in Colorado and I in California. I'm going there in August to set his scope up and want to know...
Take 6 lbs. When the scope is pointed low, and the extra counterweight Discovery puts on the secondary centerbolt is removed, 5lbs will balance a 4lb+...
Just thought I would mention that I've put my Discovery Mars Surveyor up for sale on Astromart. Thought I might mention it here to all you Discovery fans,...
I really like the concept of the split tube, but the paper sonotube SUCKS. Here is an idea to retrofit my 15 inch f/5 split tube with a custom made fiberglass...
I went and looked at this site, while it has a lot of neat stuff...there is no pricing and all attemtps at finding a dealer have led me on one big circle! Does...
I've taken a job in California. The wife and kids and the scopes are still in NY. The 12.5" Dob didn't fit in my car in NY. There does not seem to be alot of...
... Hugh, That is one helpful and nicely done site. Thanks for the info. (Boy could I have used that a couple of years back. I think I spread my embarrassments...
If I were you I'd ask Discovery Telescopes if they may supply you with what they use. I have one of their 12.5" split tube models. The equipment used should...
Harry, Regardless of what approach you take, be sure the point of focus (focal plane?) does not change in the process. I've never done this, but with cutting...
... Harry, have you thought of shipping the OTA to your new home? When I sold my 12.5 pdhq I found a corregated box maker on the internet that made me a stout...
Hi Everyone, I have a 12.5" PDHQ split tube and I'm going to be flocking the lower tube half. The instructions that came with the ProtoStar flock paper say to...
... GH, Thanks, really appreciated. I've e-mailed Discovery. I'll let you know what they say and when. I'm going to wander into the Big Dob group and see if...
To reply to Chris's post. I'm the one who bought chris's 12.5 PDHQ. I received it here in Sitka, Alaska with no problems. Chris did an excellent job packaging...
Well I emailed my question to Bill at Discovery, and his response was that the pins should line up pretty easily, but he warned me to be careful about the...

Hi, I've got a 15" Discovery TB on order from OPT. What's the current delivery time these days? Has this improved any in the past year? Supposedly my mirror...
Hi, I wanted to share something that I've found very helpful. My collimation tool is the Orion combo sight tube and Cheeshire. Since the wire crosshairs are...
Thanks for the tip Maureen! I have the same tool and have blackened the top of the Cheshire, (where the peep hole is), to cut down glare but never thought of...
