... Dob ... I waited almost 2 months. Quite a shock to me but I must've got lucky because they started on it right away. I think they already had a mirror...
Jonathan and all, I'm the other dude who had the 15" TD on order from OPT. I ordered the scope on 6/30 and recieved the mirror, mirror box, and upper cage on...
Hi all, My scope has a serious balance problem. It wants to nose dive without an EP in. I'm working on a counter-weight system but I am a bit dissappointed in...
Hi all, Here's my un-edited, super-imposed report: First light: Wow.... I targeted the moon with my 28 Uwan. I've never seen Luna in a bigger scope than my...
Hey Mark, BTW, Tonight at first light, humidity was very high. everything around me was wet! I didn't have a single problem with either my primary or secondary...
awesome, can't wait to get my scope out soon. ( I won't have a report until next because I'll be on vacation.) I think you may have seen the Dumbell Nebula...
hi, I highly recommend the "Dew Buster" and "Dew-Nots" for the finderscope, telrad, and eyepieces. Dew-nots are cheaper and take less battery power. The...
Hello, I have on the web special 13.1" DHQ telescopes. I am pleased with it - I have had to do a few things to it. I have fixed it balance problems with some...
After 10 months, the factory paint never cured; it was tacky to the touch and pulled off the tube with some of the paper after removing the vinyl dustcover....
Nice! Sounds like a bad batch of paint, or it wasnt mixed properly before they finished it out at the factory. Stuff happens. Good job on the rework. Id drop...

Currently, I have an 8" LX90 scope with UHTC coatings and I am thinking of getting a 15" Discovery Truss. According to basic formula, a 15" scope will provide...
... I'm sure you will get a more accurate answer than mine, but in general, given the fact that the dobs don't have the light loss associated with the SCT's...
When new, Discovery truss dobs have enhanced coatings, generating a 96% reflectance at 550nm, approximately the center of our visual sensitivity. That means...
Don, Thanks for responding. You bring up a valid point – secondary's size. Also, I found out that my prism diagonal has a light transmission of 85%. I did...
Why would you use a diagonal with a dob? Don ... From: "GG" <ggleyzer@...> To: <Discovery-Dob-Users@yahoogroups.com> Sent: Thursday, August 10, 2006...
Don, My comment bellow is not very clear. I wasn't talking about using diagonal with a DOB. What I meant is that it has to be used with an SCT. So, when I did...
Hi Mark, I talked to my guy at OPT yesterday, and he said that you also have a balance issue. He also told me that you and a friend are working on a system....
While you guys are looking for a system, I have the Markless system that works pretty well. If you want to see how it looks, let me know and I can send you a...
I've been eyeing the markless system, and I've seen it in a few pics. Is it easy to mount? What weights will I need? I have the 15" truss. Thanks ... ...
No problem to mount. It's held in place by 2 screws. I have a 1# hand weight (had to do a little innovating to attach it when needed - using a C shaped pipe...
