While I heartily agree with Mark and Bob, Dennis should know that Galaxy and OMI, at least (and likely Swayze and Zambuto) publish their mirror specs on their...
Hi Dave, When my Swayze mirror was ready for delivery, the only quantitative figures Steve gave me were his assurancethat it was a good mirror and a a smooth...
Hi, I had Steve Swayze figure a mirror for me about four years ago & it gives excellent views. Steve did not give me any numbers but I can tell by side to...
We are considering a folded Newtonian for our club telescope. The main advantage is to reduce eyepiece height and need for tall ladder for both club members...
Hi Ken, depending on the size of the telescope, you migth also consider tilting the secondary stronger than in the classical Newtonian. This avoids the need of...
... also need a larger secondary. ... Hi John this is true, but you can't do this to an arbitrary extent as you will run into serious baffling problems at some...
Hi Ken, I guess it depends how many mirrors you plan to use. A three mirror system would be an extra step. I started with a two mirror system then I added a...
Hello all, I going to refrain myself from commenting on Vids posts other then to say get your facts straight! First off I am still building Telescope up to 28"...
Hi Mike, Could you post your email address & ph # for those of us who don't have it or forward it privately if you prefer. Thanks, John Vogt ... but ... good...
Hello Everyone: Last week at the Okie-Tex Star Party I did a quick introduction of our new 30 inch Dob, the Evolution-30. The design of the scope is based in...
James, After having used Jimi's scope I am sure this is a REAL winner! Jimi's is SO easy to use - smooth and robust feeling... with incredible views. Congrats...
Thanks Gary. The pointing and tracking accuracy on Jimi's 48" is also a testament to the Argo/ServoCat system. Your stuff works amazingly well. James James...

Hi Peter, I had seen your project on your website some years ago. It is nice to see now the finished scope. Did you make both mirrors yourself (the primary...
Hi group, Sorry for this off-topic mail. A while ago I got an invitation from a person named Nick Hanson, supposed to be in this forum, to join "grouply". This...
We are between new moons - a good time to outfit your big Dob with accessories which add to its ease of use. Some mid-autumn star parties are in just a couple...
... In a folded design, the optimal shape for the sec would still be elliptical, but less eccentric than usual. That wouldn't be too hard to make. Mike...
Many people think "grouply" is suspicious. I believe the idea is that a member can get all his group messages sent to one place (presumably from more than...
Egads, a UC 30" at 350lbs. Tyranno-telescopus rex. If you are willing to share on-group, Jim, what will the pricetag be of this scope? Not that, after the past...
Scott: The Evo-30 will weigh about the same as an Obsession 30. It's not an ultra-light by any means. We're going for precision and compactness for transport....
I am wondering if anybody else is having a problem with ProtoStar or if it just me.... I ordered a curved secondary mount and secondary mirror from them on 14...
