Hi All, Just had to post a couple of pictures of this conjunction. The first one was shot during sunset, with the cloudes presenting some really wimsical...
... Well, it was probably there all along, and that's why the last person sold it (since he probably never understood what was happening). The reason the...
Rolando, Thanks. I haven't detected any play in the RA axis, but will try the "new" one-finger method to improve gear mesh. No backlash is currently dialed in,...
Changing your RA mesh will change your Periodic error. So you may have to redo that as well. What is the one finger method? ... From: ap-gto@yahoogroups.com...
You use the force of one finger to push the motor into the gear (after loosening the screws) instead of tapping with a mallot. It's AP "gentler" New Year's...
I will be receiving my 1200 in January and I'm in the market for a pier to support it along with a 10" RC, guide scope and camera(s). Since it will be 12-18...
I've used the pier tech w/ an AP 1200 GTO mount and RCOS 12.5. The thing is well built and very stable. And it can be used in the field as well. Adam ...
Roy, It's Rolando's revised instruction for re-setting worm geat mesh. As he said in previous message, "don't use a mallet [as the AP website currently...
Hi Adam - thanks for taking the time to reply. Good to know it worked with your equipment. One thing I noticed is how small the "footprint" appears when the...
Hi Dick, I have used oak board scraps and bricks. Metal plates also work. Not pretty, but they work. Adding a screw leveler as suggested is more elegant and...
Hi Ron, The Pier Tech's work well and some people really like them for the ability to raise the mount (especially those with roll-off roofs. They do move a bit...
Hi Rick - thanks very much for your good advice. I live in the country under pretty dark skies and really have never moved my setup to a remote site. The PT...
Hi, I need the mechanical dimensions for the mounting surface of the Dec head of the AP1200 and the 18 inch mounting plate including the hole dimensions and...
... This doesn't surprise me at all....too many 'plates' and heavy equipment. Don't tell me you are trying to guide the AP155 with the FSQ or....image with ...
Side-by-side Robin Casady tandem plate and dovetails enables balancing any desired two OTAs without the moment arm magnification of piggybacking a heavyish...
Inspired by Dean Rowe's CBT1 image a few months ago I gave this puppy a shot. Because of his warning, it's quite faint, I used ~23hrs total of Bin-1 data....
... The only way to make a guidescope work is to attach it directly to the main scope tube assembly. Not to the rings, not to the mounting plate but directly...
Hi Kent, I share your concerns. I will design through the flexure issues and get it working. The AP is no more likely to move in its rings with the FSQ on top...
Hi, I have worked through the mechanical design issues regarding flexure. The tandem arrangement can be made to work, but is much more susceptible to flexure...
Hi Roland, Can Howard or someone provide me the mechanical dimensions that I requested? I can drive out to my observatory to measure them, but a drawing saves...

Hi everyone, I am new to the group, having just purchased a like-new used AP1200 mount. I plan to use it with a C-14 scope that will have a 5 pound guide scope...
