Re: Larger "diameter" Counterweights for AP-1600 ?

Joe Zeglinski

Hi Chuck,

If at all possible ... it is best to AVOID using extension bars. I have been advised by an expert, that he keeps his stack of cwts as close to the upper bar as possible, and even retained his old, shorter, AP-1200 cwt bar. He says that with the large mass of cwts down the bar, their "inertia" can affect the "responsiveness", of fine guiding corrections.

Of course, this won't pose a problem for those at low latitudes, but those in higher latitudes may have no choice but to use extensions, since the cwt diameter can clip the mount post-meridian, especially the mount AZ Adjuster knob, which sticks out a bit further, beyond the pier perimeter.

Some things to consider, before going for lighter weights further own the bar, for the same leverage.

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.
