You should know as well as anyone that we NEVER have the largest aperture scope we want! ;) Bryan ... PLEASE! PLEASE! PLEASE! Do NOT make your roll-off walls so low that you only barely clear the scope. Allow for the largest diameter scope that you ever plan to own, and then allow a bit of cushion. Unless you are on the highest point on a small desert island, you won't be imaging right at the horizon, so slightly taller walls won't hurt you.

Re: APPM model how many points portable?
Dale Ghent
APPM and NINA currently don't talk with each other. You will need to run APPM by using your camera's ASCOM driver and any of the plate solving mechanisms that are currently supported by APPM.

I personally go about it with APPM connected to the camera via its ASCOM driver, and using TheSkyX's ImageLink plate solving. Once the modeling run is done, I shut all that down, make sure the new model is loaded up in APCC, then start NINA and go about my usual workflow. /dale

Re: AP1100 park position question
Hi Joe One of our local guys used the Pier Tech version in Calgary here in a Tele Station 3 for a few years then moved it to Toronto area. I don't believe he had any problems. You are right though it is an indoor rated product so one would have to keep it free of rain and snow. Don Anderson

Thanks Chris,
For your link to Linak disti’s – I was quite pleasantly

One thing that concerns me is the operating temperature

here. The LINAK is meant for “medical facilities or office areas”, and
might be a problem outdoors, if it needed to be operated unexpectedly, on a cold
northern winter day. I suppose, no problem in Hawaii.
Perhaps, once we have the scope height calibrated, the automation just
lifts quickly, so in rare use this doesn’t become a significant issue.

Re: AP1100 park position question
Thanks for the info Jack. I would be lifting an AP900 with a 5" refractor and associated guide and finder scopes, cameras and controllers. All told about 90 lb. I may at some point get a 10" or 12" CDK or a larger 160 -175mm refractor. This may push the total weight to maybe 120lb or so. Would a 1000 be good enough? Is there much of a price difference between them? Don Don Anderson

Don,
When I purchased the original pair of lifting columns from Linak, I was over the engineering department of the local public works department in New Orleans and we did a lot of custom fabrications for all of our facilities. As such, I was able to have them sell me two 1000 Newton columns and the associated controls. Since I was already an established customer, I was able to get an upgraded set of 2500 Newton columns and associated controls last year.
I do not think Linak sells to the general public.

Christopher,
The company is Linak out of Kentucky and the columns I used were the DL2 2500 Newton rated. My original ones were rated at 1000 Newtons each when used with a non AP mount. With the AP1600 and 150# of equipment on the dual column setup, I changed to the 2500 Newton thrust each – 5000 Newton total thrust.

Well, yes of course you don't need to change something if it's working fine :)

In my case there was substantial drag on the axis when releasing the clutches and moving the axes. This was because the plugs had been pushed in too hard and for too long by overtightened clutch knobs. It wasn't all that much of a surprise given the mount's age and how many people have used it over the yea. Fixing it was cheap and easy and the screw extractors make it so that you don't need to buy a tool from A-P or grind down your own using a flat-bladed screwdriver. I'm honestly amazed that this particular topic has garnered so much bike-shedding.
