Equatorial Mount's Construction

Ok I would like to collect whats out there on this subject. Please add what you have. I am intrested in finding something that is simple and effective that could become a building project.

There are to my knowledge three types of EQ mounts
GEM, Fork/Wedge, and Split-ring. Then of course there are EQ platforms.

Few that I have found
http://easyweb.easynet.co.uk/~chrish/eqnotes.htm

Dave Gault's one

see attached zip for Autocad Drawings

Simple, effective, cheap..

Fork Equatorial.. Mick Pinner is i think looking at doing this on the Dob buggy. The rocker box becomes the fork on the wedge in his design.

Split Ring design.

Eq platform.. very cool one i found.

Another one, with Dual Axis drives.

More to come..

I will add more as i dig through my bookmarks.. But this is what I have so far.

If any of you out there work in CNC shops, i would like to know what you think would be simplest and cheapest to build also.

Regards

The DWG's are Dave Gault's Autocad drawings...

Look on Tucows for "free dwg viewer"...
Or get it here..

Hi netwolf, I know this is an old post, but I'm curious about the split ring/horseshoe mounts for a Dob. Have you acquired anymore info on them?

I can see an obvious issue with using a sling-type mirror cell, when you flipped the scope upside down.
