Parijat, Roland and I will be back in the office tomorrow and will review your information at that time. We have been on the road since NEAF. Marjorie Christen

In the A-P pdf file on the 1600, it states it has a 1.875" CW shaft, same as the 900, 1200 and the optional Mach 1 shaft. From: ap-gto@... [mailto:ap-gto@...] On Behalf

Don't forget you can get an extention cwt bar, which cost much less than the weights. If the 1600 couldn't use the 1200 weights..that would be a deal breaker for me. Chuck/divenuts

Hi Marj, In the tracking curve I had uploaded, you can see PEM was always disabled (red button on the left). So I had ruled that out

Just FYI, USPS Flat Rate Priority Mail within the 50 states goes up to 70 pounds and "If It Fits, It Ships!" The last time I shipped 50 pounds of couterweights from Hawaii to New York, it cost me

Hi Joe, We will evaluate the need for an additional cwt suitable for the increased capacity of the 1600. Marjorie Christen

Subject: Re: [ap-gto] Re: Larger "diameter" Counterweights for AP-1600 Lately there has been considerable discussion regarding c/weights. For anyone interested I have the ultimate c'weight for

Thanks again, Fernando, Got an email reply from PlaneWave, and just as I calculated - their #600111 AP-style 40 lb couterweight is indeed 8" outer diameter, by 3" thick, with an aluminum lock

The photo shows the 1600 w/ the new 175mm StarFire, 305mm Riccardi-Honders and 305mm Mak-Cas on a special plate we made for the test. The instrument weight exceeded 220 lbs. It was quite impressive!

I suggest that you disable the PEM first and evaluate the performance. The rest of the steps you mention may not be needed if the problem is dur to an erroneous PEM curve. Marj Christen

Thanks Fernando, That is good information. While looking for heavier counterweights for my RC14, I did buy a couple of those 21.7 lb Cassady's. I didn't know that Planewave has the 40's, for the

Saw that pic, too. It also had the Maksutov in addition to the 175 and RH. Shweet! :) Eric

Marj showed me a picture of the mount while it was being tested. They had the 175 and RH, and maybe even something else on it with a long shaft full of weights. Looked like it had an extension on

Hi, Joe FYI, if someone wishes to use heavier counterweights to fit the 1.875" ctw shaft, there are 21.7# weights from Robin Casady, & 40# weights from PlaneWave Instruments, available for

Roy, Don't see where you got 110 lbs and AP-1200. Granted, "old" AP-1200 carried that without breaking into a sweat, with bar space to spare. But, my post was actually about the new AP-1600,

Joe, Balancing 110 pounds on an AP1200 with three weights not all the way out the extender and (eyeballing) space for maybe six more weights (true most would be close in but not all) seems to be

Hi Marj and All, Thanks a lot for your valuable suggestions. I now have a good list of things to check and ponder on. I am planning to remove the 3 gears and carefully clean them well, and apply

Hi Robert: I love the 'drift' method and used to use it all the time with my old G-11 and AP1200GTO mounts. However, once I bore sighted my polar alignment scope I found that was all I needed

Hello to all, i have a problem, In English when I go to balance in declination my optical the plate of the declination becomes much hard one to move as if it crawled therefore becomes impossible to
