12693Re: New APM lightweight tubes w/Feathertouch Focuser
- Dec 4, 2003I just recieved one from APM with a 100/800 lens
mounted in it. Initial impressions are very positive.
Fit and finish are superb. I had been concerned about
whether the sliding drawtube might wobble and affect
collimation, but it is very tight even with the locking
screw loose -- no sideways motion or wobble that I can
detect -- if there is any wobble its not more than Jupiter
diameter. Hopefully it stays that way; time will tell.
Sliding dewcap is a bit tight and some effort to move,
but may be just stiff from newness; better than having
a droopy one. FeatherTouch is wonderful, of course.
Nice deep slip-on metal lens cap; not likely to fall off.
I personally would like to see a handle on top of the
rings; this one did not have a handle and tube is a
bit too fat to grip with one hand. And of course the
best part is the optics! - John B.
