6" or 150mm Newtonian f5ish Dob Mounted anyone?

[Alan White]

Has anyone got a shorter 150mm or 6" Newtonian that is Dobsonian mounted at all?
If you have please can I have your thoughts and any images of the set up please.
Thanks in advance, Alan

It would be fairly simple to make a dob mount out of plywood and mount an explorer 150 F5 dob style, im pretty sure its been done

Orion (USA) has the Orion StarBlast 6 Astro Reflector Telescope.  It is an f/5 scope.

It is entirely possible, of course, but the eyepiece height will not be comfortable without an oversized rocker box or a riser. I had my 220mm f/5 (1089mm FL) on a dob mount initially and even that was low. I’m not aware of any commercial 6” dobs with reasonable EP height so you’re probably forced into diy territory.

OO might build you one of their dob mounts in a higher version. Their 6" f11 needs quite a high mount anyway. This is Shane's scope.

Check out Howard's 8" f/4 with a mount that keeps the eyepiece at a constant position.

It could be a taller version of a normal Dob mount.  But the taller it gets, the more "shakiness" or instability it will tend to have.  It could certainly be done though, if you're handy with tools and DIY.

Buy an old surveyors tripod, very sturdy and heavy, from eBay and fix a regular dob mount to it. The yellow wooden ones £25 - £35.

Moonshane made one and detailed his build here...

One of the most "inspired" constructions I have seen was where a guy had built his own with a bottle jack for adjusting the height. 

The jack, a 3 tonne(!) capable one, was welded to a metal plate at the bottom, which had holes drilled to screw it to the dob mount turntable. Top of the jacks pillar was welded to a smaller plate which was screwed to the bottom of the dob rocker box. End result it worked and stayed steady enough, though never had its height raised by more than a foot.

SW Heritage 150 Flextube is F5. As is the Bresser 6 inch F5 solid tube dob, that Harrisons sell. 

Both have the OTA on a single side rocker. The Bresser tube is in rings attatched to a dovetail which is what is attached to the rocker. Handy as OTA can go from dob mount to another type quickly & easily.
