I got in on that May sale at the 11th hour yesterday. I just couldn't resist the discount offered. I've been meaning to pickup a dob and that just sent me over...
Hi Chris, Congratulations! Once you receive your scope you'll probably want to "tweak" things to suit your needs and this group has a lot of experience with...
This will be my first reflector of any kind so I'm completely clueless on this matter. What do you all use to collimate your scopes? I was looking specifically...
I use the orion Cheshire combination eyepiece/sight tube. It's very simple and accurate. I got turned off of the laser collimators when I started reading...
... I'm firmly in the laser camp. I cannot get myself organized to get to the observing site before it starts getting dark, which makes it much more...
... clueless ... to ... Chris, Here is Mel Bartel's web site for collimation. http://www.oarval.org/collimatE.htm It's a very good site in that it gives you...
Chris, Put me down as firmly in the "Non-laser" camp. With the exception of Glatter lasers, the odds are high you will have to collimate your laser right out...
Star-gazing on a work night this time of year is somewhat pointless at my latitude of approx. 46* N. (unless you're viewing a planet or the moon). It still...
Hi Don, I'm assuming you use or have used the Cat's Eye tools? The Cat's Eye system will be my collimation tools of choice I think. On his site he mentions...
Chris, 1. I use the 2" Catseye tools. They are easier to use than the 1-1/4" versions, and since Nearly all my eyepieces are 2", it made sense. 2.The center...
Just a heads up... After having the vinyl dustcap on the primary mirror end of my split tube for a couple of months, when I removed it , a couple of chunks of...
My dust caps (the black shower cap type) are on for two or three weeks at a time and have not been a problem. My tube is covered in something like Monokote, a...
Hi, I'm new to this group. I'm planning on buying a Truss Dob on Thursday. I'm looking for good aperture-- enough to see plenty of galaxies, up close on...
The mirror box on the 17.5-inch weighs a ton. Our club got ours cheap because the original owner just couldn't handle it after just six months of ownership. ...
I'm betting you live in a hot, dry climate. I had a similar problem when I relocated my Telrad base. The 3M adhesive pad took off part of the finish, so I...
... Telrad base. The 3M adhesive pad took off part of the finish, so I went over it with some of my wife's clear nail polish to protect it from dew. ... of ...
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+...
