Criterion Dynamax 8
I actually own a Dynamax 6 SCT - excellent optics (diffraction limited), stout mount with jewelled controls, but will not fit standard SCT tripods - very easy to use, and I got an incredible deal on mine so value is sky high. Overall, a very nice tabletop scope with lots of features and good optics.

It is still a good workhorse, although there isn't a good way to re-coat the mirror or even open it.

Criterion Dynamax 8
I have 2 Criterion Dynamax 8 scopes that I picked up for chump change on A-Mart. They are in excellent condition. One is a 1976 model and the other is a 1979 model. Read my review of these scopes on Astromart in the "Cats" section. Both of these scopes have excellent optics. The 76 model has shown incredible detail inside Jupiter's red spot. I have seen shades of white, red, orange, and brown. Views of deep sky objects in both scopes have the tiniest star images you can imagine with great contrast and resolution. I had to tweak the 79 model to get it to perform at this level and that is explained in my review. This review is also on Cloudy Nights.

I use a telrad on them and when I am in a lazy mood I just use the settings circles with great success. Tracking is excellent and very quiet. They also have an 8X50 finder on each one. The bakelite tubes are very strong and attractive.

The mount is very steady provided the legs are not extended to a high position. I extend them an extra foot or so from the lowest point .

Any 2" Diagonal threaded for SCT will screw into the back of a Dynamax 8. Any SCT f6.3 focal reducer will thread into the back of a DX8. Any skylight filter dust seal will also screw into the back of a DX8. This in turn will allow any Meade or Celestron visual back to thread into the back of the dust seal.

I have an 80mm f6 Nighthawk achromat that does not provide sharper views on stars than the DX8 scopes. It is a sharp refractor, but no sharper than the views I am getting with my WELL COLLIMATED Dynamax 8 scopes.

I enjoyed using my Dynamax. Long cool down times are required. Years ago I recall a view of the orion nebula that I'll never forget.
