Last night I was looking at Jupiter with my 12" Dob, which was very low in the sky, on my observing chair set to about 6" off the ground and I was having quite a problem getting low enough to look through the eyepiece. Has anyone built a platform to put a Dob on to raise it higher? Any links or pictures? I didn't find anything when I did a search. Any recommended products that have been made for this? I think I am getting to old to get this low. I even bought a Celestron Evolution 9.25 for most of my observing for this problem. Thanks for any information.

Orion has a Dob Pod for scopes up to 10" so  you'd need to beef it up:

This DIY would be another option:

Pogo007, thanks for the link for the wheeled dollies but I need something that is as high as possible that is still stable. So far I prefer something like the youtube DIY posted by S.Boerner but still open to suggestions.

Here is what I did.  I made two option.  A tripod to use when standing and a triangular base to use while sitting.

Sputnik - here is a pic and the sketch for a stand I made.   You'd have to make some changes in order to raise your scope higher but that wouldn't be too difficult.  The screw down feet are for leveling

I've since added lockable caster wheels at the three corners slightly behind the screw down levelers.

The best thing to put under a dob is an EQ platform but it only adds 4-6 inches.

Three concrete blocks in a triangle would do the job, if you don't mind the weight. I've also used flower pots upside down.

"Milk Crate" storage containers do well; depending on the size of your scope. They also help haul the accessories outside.

I made a 3 legged stool and attached it to the base feet with screws so it is somewhat permanent.  I was able to modify the wheelbarrow handles so they still work.  Makes it much easier to view at all elevations as this is a 12" F/4.

 

Also you can see that I can leave the wheels on now when observing since I reversed them.

Thank you all for your suggestions. I am sure I will incorporate many of the ideas into my design.

I used 16" Hairpin Table Legs on my 6" dob.  They also come in 6" & 28".

I removed the ground board circle and attached 3 of the four legs to it.  I glued the hollow plastic spindle it rotates on, to the ground board so it wouldn't get lost as it was only held in place by being a snug fit.  I then had only 2 pieces and both were too large to loose.  The bottom being about 10 lb and the top about 45 lb.  Forty-five still sounds like more than I wanted so wheels were next.

My choice for my similar sized dob, was to rotate the focuser position up hill 45 degrees.

By moving the altitude bearing positions accordingly, in my case.

Rotating the upper tube assembly also works.

No extra gear is then required.

I am tall, so 45 degrees works for me.

Less could be better for others.

Stooping to view through my 8" dob was a problem for me when I had some back issues. I upended 3 cinder blocks and set my dob on those. Quite stable.
