Is there a G-11 style dovetail plate that would allow me to use the outside holes on the CNC rings, so my telescope is held by 4 rather than just 2 screws?...
Hi, Mike: I use the Losmandy DAP5 dovetail plate for Astro-Physics 5" refractors with my TMB 130 CNC. (See the plate described on the Losmandy web site at ...
... Hi Greg, I meant to jump in here earlier but have been busy putting my TMB-229 back in place on the mount. As for Lithium grease I'm not sure it posses a...
... What is the spacing of the outside holes? ... Yep, I think you're worried to much, but at $6K I don't blame you. The 1/4"-20 bolt can hold a lot of weight....
... I make it at 2 and 3/8" but I am sure it's really some metric number. Not published. Markus or Thomas know? These are the CNC tube rings for the 130 CNC LW...
Hi Terry: I hope you sign up for the C14 yahoo group: groups.yahoo.com/group/c14 Like you I've noticed that the 250x range is hard to hit with a C14. There is...
Interesting, never heard of it. On the sct-user group, whose membership includes a number of machinists, there's a fan base for Dow Corning High Vacuum...
Seems like you are still only using one bolt per block to attach those to the dovetail right? I was hoping to use two bolts per ring straight to the dovetail....
if you go to my webside to the specs of your scope your will find the info :-) The tube rings are flat on both sides and offer three tapped 1/4-20 inch holes...
Hi, Mike: No, not at all. As I explained, each mounting block attaches to the tube rings with two 1/4x20 bolts, and the two assemblies mount to either end of ...
I use the center hole of the Losmandy DA dovetail adapter to the center hole of the rings. So that's the two screws you are concerned about. I have further...
This may be the ticket then! I'm checking on the SoCal astro bolt pattern, to see if they match the 60mm Markus chimed in on. If not, I am getting the blocks...
... That is the ticket and 60mm is the standard Losmandy spacing. At some point I had adapter blocks made but for 3.2" spacing. For high strength bolts check:...
... I'm not sure why the machinist haven't heard of it. It could be relatively new, as in a couple years. I've heard of the DC high vacuum grease. There is...
An update on the nine Paragons that I had in stock. They all went out today by Priority Mail, insured and with tracking. All customers that wanted certain...
Greg, Thanks for the invitation. I decided to get the Zeiss zoom, which arrived today. After I thought about it a while, I decided that would be the best long...
Tim and Mike, I am not sure the high strength bolts will really help anything. As Peter pointed out earlier, the weakest link is the aluminum threads in the ...

Many of us SCT owners strongly advise against the 55mm plossl. Although at first glance it is a cost effective way to get a wide field, it has a dramatic...
Greg, Thanks, I have had one before; used with my 12 LX200. I have a Pentax XL 40mm already, and I know the difference in AFOV is slight, but it will give...
Jim, Another excellent image, though the cloud belt just to the right of the GRS is completely blown out. Maybe reducing you exposure time will prevent this....
Thanks Terry. You are correct. When I was imaging I could see that the area next to the GRS was the brightest on the planet. I decreased the gain and...
