My 1200 GTO is 19 years old.  Lived in a garage & was rolled out for imaging until last June when I finally had a roll-off.  C14 piggyback with a 150mm refractor & cold cables.  I regressed the mount twice I think.  Here is tracking data from a couple nights ago from MI.

Good job Roland! Looking a lot like Calgary right now. I just got back in from shovelling. You have more snow than we have at this point but it is still coming downEmoji
Back when I was young in 1971 I worked up north of Ft McMurray. Temps got regularly down to -50F and even reached -70F for a couple of nights. Now that was cold! Axels on vehicles were froze solid!

Hi Fellow astronuts,

I'm clearing a path to the observatory so i can test mounts and scopes. Ice cold polar vortex heading our way with temps of -25 to -30 F. Perfect for cold weather testing. Of course that's probably on the warm side for you Canucs. I remember winters in the Soo when I was a kid and the outside temps dropped to 40 below. Twas no big deal for us kids. The house was small and there were 4 kids just itching to go sledding from on the roof down to the gully (snow as roof high). Parents sent us out to get out of their hair. Maybe they hoped we would get eaten by wolves. They probably loved us, but so would've the wolves. But I digress (and so should everyone in these uncertain times!)

Yes, anti-sieze is great stuff.  I use it wherever high temperatures are problematic for grease.  I've had the same tube of it for about 40 years and it's getting low!

Re: Dec limit in Mach2

Christopher Erickson
 

I assume there is nothing plugged into the ST-4 port on your CP5.

I can't think of any APCC configuration or misbehavior that could cause your symptoms. I wouldn't bother with uninstalling and reinstalling APCC.

Make sure there isn't any stray fleck of metal or something floating around in your CP5 ST-4 socket.

Roland,

I don’t have anything else running. The mount starts moving the moment I click connect in APCC. As you can see from the screen shot, I had not initialized the mount yet and I had not started the AP ASCOM driver. 

How do I completely uninstall APCC so no config or other files are left over? I want to make sure that the problem is not coming from some old file from when I was using APCC with the Mach 1.

I just went to the observatory to power things up. I started with the mount at Park 3 (where I had parked it last night).

Re: Payload AP1200GTO

Hello Geert,

Just to add to the examples given, I've also got a GTO1200 on a concrete and steel pier (3.3 metres tall but very solid) in an observatory, and the mount comfortably handles a 14" SCT (about 28 kg from memory) with a 5" refractor piggybacked.   I always slew at x600 or less.

Cheers, Chris

Hello,

 

A question: I have an AP1200GTO on a fixed concrete pillar in an observatory.  Would this handle the following load: a 300 mm f/4 newton with a weight of approximately 20kg (including camera) and piggy-back a 150mm f/7 triplet refractor, all in all also 20 kg.  Total weight of 40kg is well within specs but I am concerned about the longer arm by putting the heavy refractor piggyback on the newton?!  Side-by-side is no option, also very difficult to balance.

 

Thanks for your thoughts,
