Mewlon 300 Specs?

I'm interested in knowing more about the Mewlon 300 optical specs. Primarily, the reflectivity percentages of the primary and secondary mirrors. Are they enhanced or standard reflectivity? Are the mirror coatings standard silicon dioxide or something more exotic? Also, what is the final wave-front lambda or strehl value at the eyepiece for this instrument? Is it near 1/10th wave, or less?

Peter,

You have many great questions about the M300
If I had asked those questions I more than likely would never have bought one myself.

Pete,
I have a Mewlon 300 - exceptional scope! The primary has standard reflectivity while the secondary is enhanced. I believe both have standard silicone dioxide overcoatings. I estimate correction to be about 1/6 wave at the eyepeice which is very good for a Cat system.
The scope is a keeper.

Best,
Tom
