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

Karen would agree that we need a company cat. Nice setup and great view, Don! Clear Skies, Marj Christen Astro-Physics, Inc 11250 Forest Hills Rd Machesney Park, IL 61115 Phone:

When you are autoguiding the target is always centered so no plate solve is needed. Because of the guide commands, the internal co-ordinates slowly drift, so at the end of the session you simply do a

>>>If I leave the mount running with no autoguider connected at all, RA and DEC remain constant, as I would expect. But likely the fov would have change significantly, so your target would have

Yes, autoguider commands are essentially user initiated moves which cause the mount to go to a new coordinate every time a move command is issued. This is universal and applies to every mount ever

Unfortunately there is not. You could however do RCALs every so often. This would recenter the mount's coordinates. -Ray Gralak Author of APCC (Astro-Physics Command Center):

Hi Ray, Thanks for the explanation. It seems like undesirable behaviour, however. You autoguide because the mount is an imperfect mechanical device and you want to keep pointing at precisely the same

Hi Michael, What you are seeing is changing pointing error in your scope as it is autoguided. The amount of pointing error can be drastically reduced by using a pointing model (e.g. APCC

Math update - the RA difference is 15 arc seconds. DEC is 1 minute. Seems consistent with a slight polar misalignment. When I plate solve those two images, the difference between their centers is less

I've noticed that my 900GTO's coordinates, as reported by ASCOM (latest version of the driver) change over a session where I am autoguiding. This occurs whether using MaximDL or NINA/PhD. In both
