Rotating Rings on a budget

Posted By William Chandler

From all my NET searches, it seems that the ONLY source for
Rotating rings are:
PARALLAX INSTRUMENTS http://www.parallaxinstruments.com/ring.htm
and
PARKS OPTICAL http://www.scopecity.com/tmc.htm

(Someone told me that KEN DAUZAT http://users.kricket.net/ken/ makes them too, but his website doesn't show them.)

After performing the Heimlich maneuver (on myself) due to reading the HIGH PRICE's of these RR's, I thought, "there HAS to be a less expensive solution for those of us on a budget (and with smaller OTA reflectors, 5", 6", etc)".
(note: No disrespect intending to those Mfg's making these rings. I'm sure they are of high quality and the Mfg deserves the asking price. But that market is a bit too steap for us amaturs on a budget)
(Hey, if I could afford a 12" or larger Reflector, RR's would be the least of my worries ;-)

Has anybody come across a good idea? Anyone making something (for sale)?
a Kit? Plans?
I own a Intes Micro MN56 (5" Mak-Newt) mounted on a CG-5.
Nice Scope and mount, but what a pain to keep spinning the OTA in the ring holder every time I re-locate to a new object :-(

Feedback WELCOME :-)

Curved Secondary vane

Posted By William Chandler

I'm sure you've all read the artical on Curved Secondary
holder in S&T (last month). Looks like a neat idea.
Does anybody makes these 'commercially'?
I'm making one now for a friends 6" OTA. It's not
to hard to make, but it would be nice to just BUY
the curved vane and secondary holder if it was "for sale"
someplace. (Apogee, other suppliers, are you listening?
:-)

and opinions on yours. :-)

Of course I meant "FLEXABLE" (sorry). My fingers didn't
come equiped with a spell checker. ;-)
