I received my 17.5" f/5 truss about a month ago. Discovery still owes me the shroud, truss tube bag, Telrad, and the optional mirror cert that I paid $200...

Akarsh, Phil from Australia received his Split Tube 17,5 early may 2007 after 13 months waiting time. . Just be aware that the lead times that I mentioned...
13 months and the telescope arrived with a very large chip/fracture in it on the back during transet, the mirror is still an excellent mirror, better than any...
I'm new to this group, but not new to astronomy. I currently have a mid-80s 6" f/8 Astrophysics, a 10" f/5 Portaball, a 4.5" Starblast, and 7" Starmaster Oak...
I sent a similar post yesterday but it has not yet appeared on the message board. If it does appear, I apologize for what may turn out to be, effectively, a...
Hello John, I'm yet to receive my scope, so I wouldn't be able to answer a lot of your questions, but I guess I can say something about one or two. ... Most...
Hello John, Unfortunately, Akarsh is right. Personally when I ordered my 17,5"f4,1 TD end Octobre 2007 I knew the wait would be quite long, around a year....
Thanks, Akarsh and Johan. I guess if I want fast delivery, I go with a Synta or Guen Sheng Dob. However, if I wanted that level of scope (not that there's...
I ordered a mirror cert for $200 extra. I ordered the scope 11 months ago, got it two months ago and am still waiting on the cert and telrad. [Non-text...

Hello all, I just sent an email to bill, we will see if he answers. He didn't answer to the 3 email sent since december. I am still waiting for the accessories...
Have the spiders in the split tubes changed over the years, or are they still made by spot welding. I guess I know of no reason what that wouldn't work if...
My son has the 12.5 inch Discovery truss DOB. I have an Obsession truss Dob that I can wash the mirror in the mirror box. Can that be done on the Disovery...
Hi Robert, My 7" Starmaster Oak Classic has a metal (aluminum, I think) cell with silicone adhesive. For cleaning, I remove the mirror from the tube and place...
Hi John and Robert: I have a Discovery tube 14 inch and we travel all over with it so it gets pretty dirty. I use the same procedure as John and it does a...
I've always heard that if you can look down the OTA and see your reflection looking back at you, your mirror is NOT dirty enough to need cleaning. I'm not...
Hi, I've got a 15" Discovery truss, and when I wash the mirror (usually once a year --- or so), I take out the Allen screws holding the cell in the mirror box,...
Thank you John, Gary, Dave, Mike. This is my first mirror washing as my mirror was sheltered from the dust. But my son is new at this and thought the cover...

Hi guys, I'm new to the group but I've had my scope for almost 2 years now. Boy, time goes fast. Anyway, I know they tell you to never shine a flashlight down...
Actually, what's coating the tube is probably the same thing that's settled on the mirror. When you run your finger through it, it knocks it loose to fall...
Oh, yes. Like I said, when looking at the mirror in daylight it looks absolutely pristine. For better or for worse, I can see my reflection perfectly. ;o) ... ...
I'm thinkng of getting a high end focuser for my 12.5" f/6 PDHQ. I need that fine focuser knob. How hard is it to do and do you have any recommendations as to...
I changed the focuser on my split-tube 12.5". Changing a focuser is easy. Try your best to buy a focuser which has the same height dimensions. Without...
Hmmm...how did you know you had to do that? Were you not able to reach focus? And if so, how did you know how far up you needed to move the mirror. That, my...
I said I moved the mirror cell up, but it seems I moved it down. I moved the mirror cell down to compensate for the focuser being shorter. It was only about...
