Thanks sunrag and jehujones for your responses. It seems the AD10 base diameter (22”) and the roll kit diameter is very similar. In fact, the mounting bars under the roll-easy kit are extending out quite a bit, and should hopefully, add to the stability of the scope. The only issue I can see is that it will add to the weight of the base, for lifting in the car & transporting to a dark site. I am looking at the sheer convenience of rolling it out of the garage to the backyard, for the bulk of my observing sessions.

personally, I see myself tripping on those things. as to portability for remote observing, there is also the option to get a replacement base to use just for that purpose. perhaps you can get a folding base from Mark (Astrogoods)

Good point! With the wheels sticking out like that, it is only a matter of time before you trip.

I suggest looking into "drum dolly" or "plant dolly" available from hardware stores. These two have an inside dia of 24" and rated to hold 500 lbs.

^^^They'll work very nicely on smooth floors and pavement but look out for cracks and voids!  Their small wheels wouldn't make it over the bump from my driveway into my garage.

Long time No post on this thread!!

Anyways, I have always found the base of my AD12 too big and unwieldy to put in my small car. So thought of a nice winter break project.

 

I am thinking of making a separate box structure (the three sided vertical part of the base) that can be removed or attached easily to the top round base. My idea is to have four 1/4-20" screws permanently installed in the top round base with their screw threads protruding from the top, on which to place the box structure which will have a base plate with matching holes, then tighten it down with wing-nuts. The base plate should also help keep the sides square and rigid. 

 

Also, instead of modifying the top round base, I will use a 24" edge glued pine round instead for the top round. Since the bottom round is 26", this also allows me to add a setting circle to the bottom round base, with a pointer on the top round.

I found this very nice padded carrying case for my Z8 OTA. It is brand called "TORIBIO" and available in Amazon in various sizes as Tripod Bags and Telescope Bags. This Tripod bag ( 50" x 10" x 10" ) is what I got:

Another pic. Note that I removed the Alt Bearings (I usually remove it during travel). But the bag seems to have enough space to fit with the Alt bearings.

If you are going to make a new base plate for the mount, cut a 2-inch "flat" opposite the front panel.  This REALLY helps get through doorways and makes for a roll-resistant position when loaded for transport.

Yes.  I used to make mounts for people.  This mount belongs to my observing buddy.  You can see other mounts in my CN gallery.

Thanks for the heads up on this. I've been wanting a case for my XT8 but just can't bring myself to shell out ~$100 for one.
