Kevin, Use the Latitude Dimension Calculator. Choose the Mach1GTO…dimensions are approximately the same. https://astro-physics.info/tech_support/mounts/latitude-dimension-calc.xls

Hi. First post here. I have been patiently awaiting my first A-P mount, the Mach2 GTO, which I order last year. I understand that I'm in Tolga's first batch of ten. I suppose that with the IL stay

Don, Lubricants do have a “Best Before” date, stamped right on their containers, especially the AeroShell (recommended by AP), which has to be reliable for aircraft use – thus the prefix.

... and be careful NOT to use Mil-spec Aeroshell (designated with the letter "M"). It has a slight modification in the recipe. S

Thank you, Don. I thought I remembered A-P having a kit, but wanted to be sure. And much like a car or truck, time intervals are involved are not related to "mileage", so I figured my mount might be

Eric Lubrication intervals are dependant on usage and the environment the mount operates in. Even if the mount is little used and is stored inside, the grease still dries out. I just re greased my

Great news Tyrel! Don

You will have to re-do your PE curve. It's really quite easy with PEMPro. Rolando

Eric There have been a few threads on this in the past. For example, https://ap-gto.groups.io/g/main/message/59222 Search for secret sauce and for Aeroshell The former is an A-P product, the latter is

Getting the old grease off and setting the gear meshes properly are the only annoying parts of the process. I think there is a YouTube video of a guy doing it exactly. Just watch that and you are good

Thanks Don. I tore in to it after my first post and got if fixed. I did basically what you said. The middle gear has a hex bolt behind it that controls how much it is meshed with the worm gear.

Awesome - I was thinking about the same for my AP900-GTO lately.., Will email George as well..., Thanks, Chaps.., -- I've seen things you people wouldn't believe. Attack ships on fire off the

I bought one back in Augusto, but haven't used it yet. It cost about $42.50, and came with two containers of grease, an artist-type paint brush, and clear illustrated instructions for how to access

My Mach1GTO will be three years old in a few months, and has never been lubricated. Then again, it hasn't been used much in the bad weather we've been experiencing for months. That said, what is the

I agree, give George at AP a call. He recommended their grease kit for my 900 I had a while back. It's comes with two types of grease for the gears and worms. It's a good kit to have.

Geoff When was the last time you cleaned and re lubed the RA and Dec gear trains. If it has been awhile I would service the gear boxes and worm gears. AP has a very nice grease kit. Maybe Marj can

Tyrel Take off the nylon gear and and the aluminum gear underneath. Have a look at the small gear underneath the big aluminum gear. Could be that small gear is detached from the larger aluminum one.

Mistakes were made. Short version, I had a small 3-step kitchen ladder near my scope that I had been up and down a hundred times working on collimation. Tonight I went to fire off a pointing model and

I just downloaded an ephemeris, so the site does work.

Hi Michael. The link I provide just now is not to the apcc installers but to the nasa web site. They are entirely different things. -Ray Gralak Author of APCC (Astro-Physics Command Center):
