I had the standard hinged rings. It looks like the rotating rings are machined aluminum and probably much stronger. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Chuck Hards Sent: Monday, May 24, 2010 12:16 PM To: Utah Astronomy Subject: Re: [Utah-astronomy] CGEM (Was: Atlas or CGEM?) Wow, that's surprising. One would expect top quality for those prices. I was also considering their fully rotating rings for my 10" f/6 OTA. On 5/24/10, Don J. Colton <djcolton@piol.com> wrote:
Be careful if you get the cast aluminum ones from Parallax. They work fine but are brittle. I had a set attached to an 8-inch Mak-Newt in the car and went over a big bump. When I went to get the scope out the rings were both cracked in half. If you get them don't leave them attached to the scope when transporting them.
