Hi everyone,


What is the maximum usefull capacity of a AP Mach 1 GTO mount for visual and photographic use when it is pier mounted ?

Can this mount hold a 152mm f/8 refractor (e.g. Meade AR6)or a C9.25 or is this too much ?

AP states maximum weight to be approx 45lbs (20kg), but how does this translate in reality ?

The Mach1 will carry about 65lbs for visual depending on the length of the OTA. It'll handle a 9.25 with ease. The AR6 should be fine too.

Luke's suggestion is probably close to the mark for visual. A-P rates their mounts for imaging loads, so you can add a little more weight for visual use. I haven't tried anything over 35 - 40 pounds, because while the mount can handle the load - the astronomer cannot. :lol:

It easily carries my C925 and TMB130.

I thought 45 lbs was the max rating?

I sold mine and have a 900 coming soon since I was worried about trying to image with it and my T0A-150 as it would go over 50 lbs.

A long refractor will be worse than a short SCT for the mount to handle.

I put it on an AP pier and find no problems visually with a C-11 or Tak FS-152. Haven't tried the TOA on it but did mount a Meade 102ED side by side with a Celestron ED100. Both largish scopes. As stable as required and the tap test was about 1 - 1.5 seconds to settle. The Mach 1 is one solid piece of gear.

A tube with a long moment arm as your AR6 would fit on the Mach1. The largest I have seen was an AP160.
That's pushing it but doable for visual. Note that a TOA150 is noticably heavier than your AR6.

An 11-inch SCT would be feasible, or a 12.5 inch Gladius Dall-Kirkham.
That's the max aperture that would still function. The Gladius is an open OTA, so less windsurface. Weighs just 30lbs.

The Mach1 is a great piece of gear.

There are a few people using the TEC 180ED for visual on the Mach1 (see TEC forums). They were saying for those scopes they need the Mach1 on a pier for the stability. I use my 160 on it with no problems, except for in higher winds. Mine is used on the AP Wood tripod.

Anyone try a C14 on one of these mounts? Those are supposed to be 45 pounds so would probably be a few more with accessories.

A-P certainly gave me confidence that the Mach 1 would handle my 140 EDF with 4" focuser, which is basically same weight as the 160. I've only used it visually so far but it has had no problems with the OTA and I won't hesitate to use it for imaging with the 140, guidescope and rest.
