Well, if a new AP900 replacement is in the offing, I did a little math to see what capacity might make sense given the gap between the AP900 at 70 lbs. capacity to the AP1600 at 225 lb. capacity is kind of extreme.

Relevant capacities:

Mach 1 GTO: 45 lbs.
AP900: 70 lbs.
AP1200: 140 lbs.
AP1600: 225 lbs.
AP3600: 300+lbs.

(A) Midpoint of AP900 and AP1600: This is 150 lbs capacity. While that's a nice capable amount, it is also right on top of the old AP1200's capacity. I therefore doubt this is the new capacity.

(B) Midpoint of Mach 1 GTO and AP1600: This gives a value of 135 lbs. Again, it's another alternate version of the AP1200.

(C) Uniform Load ratio. Interestingly the Mach 1 GTO carries basically anything up to a C11 without thinking about it, and can even take on some larger stuff when you creep up to max capacity. For a mobile mount, this seems just about ideal, so I would be surprised if they are going to play with this capacity. Going to 2.25X this capacity gets to right at 100 lbs. That's a large step beyond the current AP900, but would still leave a step of 2.25X to the next larger mount at the AP1600 without being a copy of something else currently in production. Given the number of telescopes the AP900 is *almost* big enough for, I would peg an AP 900 replacement at being 100 lb. capacity. There would be obvious moblity improvements over either the AP1200 or the AP1600, but it would be a major step up in carrying capacity, which would greatly improve its utility. The exact number may be 45 kg, or it might be 50 kg, which would give it a capacity of 110 lbs. Either way, this would appear to be a very practical design point for a hypothetical AP1000.
