Trever:

I echo Daryl's comment about not being disappointed. Please post back with pics and your impressions.

Does anyone know of an Alt-Az mount of some kind that is available for large refractors such as my Meade 152ed refractor? I was thinking of getting another CGEM with an extender in the near future but I wanted to check first.

I will say that these scopes are bigger than the standard F/8's offered by Synta so it would have to he hefty.

I've used a Giro II DX with a Meade 178ed refractor. It required counterweights on the opposing side, of course.

Right now I use the same mount with a 9.25" SCT~~~~6" f/8 refractor. Both OTAs use 2" diagonals and binoviewers. Just find the balance point and you are good to go!

The mount works beautifully and is very affordable.

Someone call the Navy, I believe there's a missile cruiser missing some equipment! ;)

Actually I am working on mounting an ICSM/ICBM to the side of each scope. Just because I can, not necessarily because I should.

Now THAT is a setup! :lol:

My DM6 assembly is due to arrive today. When everything is assembled, I will post pics. Can't wait to get it all together. The weather here has been the worst I can remember. I haven't had a scope out since March and then it was only one night. The refractor still has not had the chance to see starlight.

Here is the final assembly with my Refractor mounted on it. This easily is the best mount I have owned and it is so smooth! The tripod is solid as a rock and work great with the mount and scope together.

I will still need to work with the Sky Commander but that will have to wait until I get a clear sky. I have not had the chance to take this out as it has rained practically every day for 3 months and it is thundering now even.

My opinion may not be as well known as many here, but I can say that this mount is a winner! I definitely recommend it for anyone needing a quality Alt-Az mount for their Refractor or CAT.

Congratulations, Trever :waytogo: I'm sure you've realized by now that pictures do no justice to the beauty of the mount and, in particular, Tom's tripod. I also have the walnut finish and it's like fine furniture.

Enjoy,

Tom

I use a Sky Commander on another setup. The Push-To is accurate. Enjoy!

Curious, says 40lb capacity.

Could a DM6 handle a C14 ?

Jae:

The 40 lb capacity is very conservative. Tammy's WO FLT 152 pictured on the 1st page of this thread is ~45 lbs and others are mounting 7" refractors on the DM-6. Here are some pics:

As solid as it feels, I would think it could hold it. But none of my scopes approach that weight so I can't really say.

The DM-6 certainly seems to have its followers. What exactly makes this superior to other AltAz mounts?

I am just a new owner, but the construction is first rate, the motions are smooth, no weights are required to balance the mount, accepts encoders and Sky commander, different configurable options, and adaptable to many good quality tripods.

Many others may also have these features, but I felt that this one was best for my refractor.

I also have a DM-6. It is attached to a used G-11 tripod. I added the G-11 extension tube so I'm not lying down while viewing near zenith.
It handles my TEC160ED very easily. I agree that the heavier the OTA, the smoother the motion.

This thing is VERY stable.

Really cool pipe mount!
One of the most bang for buck ways to mount a scope.
