... Hello Alan: Quite true. Particularly if the objective is primarily used for planetary, lunar and double star work. Then the gain becomes miniscule, and...
My old Cave from that era, which I Dobized, had aluminum pillar legs for the mount and a fiberglass tube, I believe of Parks origin as they were around then....
Gary; If the baffling is "tight", say of a diameter to give a maximum fully illuminated light cone of under an inch or so, then I believe that the air currents...
Manand; Probably the easiest method would be, if you have the photo tripod and head already, to just tap a 1/4" x 20 threaded hole in the bottom of the...

Bill G; In an email to me you commented that you wished that Rolando had commented on Newtonians too in addition to SCTs and Maks as far as performance is...
... Interesting.... ... Good point, so many variables.... ... Is the reason higher f ratios Newts are more desirable - cause they have smaller secondary...
... I spent a lot of long nights working there on the image processing system that I built for it. It's not a visual scope though, you look at everything with...

Roland's post makes a point, but only so far. If you set up an SCT the way you set up a dob then it's pretty simple. Hooking up wires, things start to take...
Hi Rich the Blanks has been melted and getting polished, there is a consortium in USA/India, who raising funds to purchase the complete equatorial mounted...
Hi Vahe there are quite many TMB 10" owners in USA and the once to whom I sold them, reporting fantastic views and no problem , I self running my 12" TMB...
Hello A few days ago I posted this on ScopeMounts but I only got one response. I'm hoping more of you will give me some advice. My Stardust Blue Stellarvue...
The Celestron Alt/Az is a very light weight portable unit. So light I have decided to fill the lower legs with either lead or cement to change the center of...
Hi Derryl, There are certainly plently of candidates to choose from. I have an SV Nighthawk Classic and it weights about the same as your NGNT. I picked up a...
There has been much talk about field flatness in this group. I thought that a general discussion about field flattness would be helpful. Comment on my below...
Derryl.... If you are only using an 80mm scope, and want this mount set up for only it, and not larger scopes, IMO, you can get away with a lot, as long as you...
... As Rich is demonstrating, there are variations on the baffling theme. Alan French's original post on the subject expressed a concern that baffling has at...
Bill; Opinions on Newtonian F ratios vary but IMO a somewhat longer F ratio in a Newtonian has three advantages. First is it reduces coma. Second is that it...
Markus; I suspect that thermal problems are going to be dependent on location in the U.S. In the high altitude and low humidity areas west of the Rockies we...
rich, I fully agree with your points.... all valid, so why not more higher f ratio Newts on the market? f6 to f7 would be nice, right? I guess its the...
I'm debating whether to get the Losmandy 5" rings or 6" rings for this job. The 6" rings add to the moment arm and balance issues (by one inch, I suppose, but...

Gene, All good points - and if you want a longer focal length scope, why not just buy an SCT or Mak in a more manageable tube length? Timm ... more ... 12" ......
Thanks Scott, This helps me understand it, greatly. That's the best explanation I have seen of how it all works together. It also seems logical to me now that...
Hi, There are lots of choices, in various prices. I spent my money on a William Optics EZTouch, made by AOK of Switzerlanf, my review of it is in the list...
... With folks taking 20" and larger Dobs to dark sky sites, I would think it would be relatively easy to pack up a 10" or even a 12" f/6. Heck, we've got a...
