Kevin, Or it might be a case that the 2nd generation is selling off Dad’s old astronomy gear. And not everybody keeps old receipts or records. Just trying to think on the positive side.

The version on CN appears to fraudulent. Bummer

Well ... privacy rules would probably preclude Marj and the gang giving you a lot of details about the seller but hopefully they can confirm that the mount is theirs (since they claim to be the

I may have some valuable info for you. Please contact me off the group.

There are people who make investments in expensive gear because they can afford it. Those same people don't always figure out their expensive investments and sometimes that gear goes into storage and

Thank you for relying Stuart. The seller is having trouble answering pretty basic questions about the mount, though he/she is the original owner. I have a bad gut feeling. I think I may have to pass,

I'm sure a call into AP will answer your question exactly but if it you're needing the info now, I have #501 and it was made ~ 2000 and was a CP2. Stuart Heggie http://www.stuartheggie.com/ --

I am looking at buying this AP 900GTO and am wondering if there is any info on this mount, such as year produced and was it originally a Cp2?

Yes, Stephen. Please call the office during the week. Clear Skies, Marj Christen Astro-Physics, Inc 11250 Forest Hills Rd Machesney Park, IL 61115 Phone: 815-282-1513 Fax:

Just ordered one. Maybe two? Very high humidity here in S.C. I also use a TGZ 365 Jim Get Outlook for iOS

The Goldenrod gets warm, not hot. I can easily touch it when it’s running. To mount it, I used the plastic stand-offs included with the Goldenrods and attached them to thin strips of plywood.

Since the goldenrod gets hot, how do you attach it to the mount? Jim Get Outlook for iOS

Ouch! Happened to me TWICE! Once with one of those "red" mounts and then once when a few of the critters got into the OTA of my Planewave 12.5" and down behind the primary and ate EVERYTHING. OMG.

I use a TG365. I’m using a C8 for imaging, but I bought an oversized one, meant for a Dobsonian. That way, it covers everything, all the way down to the ground. To keep the humidity under

Does AP still have/sell touch up paint for the cream textured finish on their mounts? Years back IIRC, the touch up paint was a two part paint with a catalyst/hardener. Thanks, Stephen

Thanks, Marj. Kulu is one of three cats that showed up at our house as kittens one day about ten years ago. She’s the only female and always comes out with me to the observatory when I’m out

The mount itself doesn't move in Dec, so all drift is due to external errors (atmospheric refraction, differential flexure, polar misalignment). Most Dec drift is simple polar misalignment in azimuth

You do need to recalibrate after flipping to account for orthogonality errors. And you'd have to slew to the same coordinates reported by the mount just before you flip, which differ from the target.

I think you misunderstood. I do the same thing with ACP. Each time the mount slews to the target, e.g., initially, after an autofocus, or after a meridian flip, ACP performs a plate-solve to center

Hi Wade, what covering did you use? I think I'm a couple of miles as the crow flies from your location. Now that someone is always home due to COVID, I've used a simple nylon tarp for about a week and
