Also, what materials are the mirrors, are they Pyrex? Also, are the mirror coatings enhanced?

Hi Mike, is the 2" visual back use set screws or is it of the compession ring style? I think the design look real good, and very affordable for a 6" Rumak MCT, wanna see one up close, the pics on the site just tell some of the story but looks good so far. :goodjob: :goodjob:

Hi Mike, I was wondering if your company has brought any of these scopes to an optical lab for testing of the optics like P/V wavefront error or Strehl ratio. That would be nice to see how they do up against the russian mac's which seem to be the benchmark for MCT's nowadays. Its nice that the scope is of the Rumak design and as long as the factory placement of the secondary onto the corrector there should be no need for any collimation issues except for the primary. I kinda like the way this scope has the added plusses on the cool down with the 1" plugs and I am sure someone will fit small micro computer fans on the back of these for faster cool down. You might want to change the finder bracket to use the more standard Vixen finder shoes. The scope does not seem to take any of the standard SCT adapters in the back but look like it has a 2" opening which would make it very good for placing DSLR's or CCD imagers for planetary AP work, different but nice for some that may want to image with this scope. Overall your scope looks real good and let the Might Kong live long! :bow:

The similar Bosma is advertised by a vendor as:

"Secondary mirror diameter 48 mm - physical diameter
57mm - total obstruction including baffle - this baffle is often ignored in technical specifications."

That would work out of 38% assuming the primary mirror baffle doesn't add. That would be quite typical of maks or SCTs of this aperture. The rumak design likes to evolve to longer F#s for the primary, probably about F3ish.

Hi Mike,well I pulled the trigger on the AT6M, talked with Fred over the weekend and he was holding the demo scope on his desk for me so I ordered it up on monday but since you guys have that bad ice storm it wont be shipped till mid week maybe. I didn't know Fred was the owner, very nice fellow and he did say that the demo unit doesn't have the compression ring visual back so I'll be ordering that when the next batch comes in. I hope to get the scope ot when it comes and if you like I'll report back. A astro buddy bought the one you sent to your NJ dealer right off there sales floor and he so far likes the scope, put it up against a Meade 102Ed and the MAC blew it away,no false color,very good star test and sharp stars right to the edge of feild was his report so far and much better contrast on M42 over the 102ED with greater nebulosity.

Hi Doug, even on most all sct's the secondary baffle is not speced out but in most its a few mm larger than the secondary cause of the steep light cone. Anyway I just received one of the demo's from Astronomics on the AT6M, real nice scope so far bur its outside and letting the lil puppy cool down and ready to rock. I called up last weekend to order one and they said all they had was two demo's left, Fred gave me a nice discount on it and had it shipped on monday, all the synta finder shoes fit and its fit and finish is real nice. Will see how it does on the moon in a few min..

Mike, how about the AT90EDT "Lite" version? I would think the inventory on the standard model is starting to thin down.?

I would think the TMB 92 SS L would compete. Likely the 92 glass and cell with the AT tube, focuser, etc.
