I'm thinking it would be best suited to a dobsonian mount, but I love the tracking feature (don't care about a GoTo feature but I do like not having to constantly keep what I'm observing centered in the EP. I decided to build a mount tonight and am searching the web for plans and examples but I thought I would pick ya'll's brains for ideas as well. I think the only bell or whistle I want to add is tracking. I'm hoping I may get some pointers and ideas from ya'll before I start to cut wood.

Why is it too big for the mount? Just picking your brain. -------------------- Mark "The only thing wrong with immortality is that it tends to go on forever."

Mark, it's the 10 inch mirror and it's too shaky to use for imaging, I always end up pushing it around with the clutches unlocked until I find something I want to look at. My thinking is the mount will be better served with a smaller scope (I'm saving up for a solar scope) My father also hates the eq mount, and I'm looking for a project to do with him. --A Post Extras:       MMICKELS Aluminum Knight Reged: 01/20/04 Posts: 25192 Loc: The Land of Shake and Bake Re: Converting my EQ newt to a dob [Re: Allen]       #306434 - 01/10/05 07:02 PM Edit   Reply   Quote Quick Reply   Allen, somewhere in this forum was a "clam shell" that a guy built for his newt. This device allowed him to use the scope as a Dob (with the clam shell on), or as an EQ newt. -------------------- Mark "The only thing wrong with immortality is that it tends to go on forever."
