Roland, I would want F-8 or F-9 for imaging. Yes, it's slow, but that's why you make the 1200. F-9 hasn't slowed down the R.C. market, and F-9 is only slow in the film sense of slow. Typical long

Why do you think some people have been buying the longer focal ratio TMBs? Maybe they are AP customers who didn't see a chance of AP ever making longer scopes? Rich

Does TMB offer a 7" f/7? I thought they were buying the longer focal length because this was the only selections offered!

Is there any chance the AP 2.7" and 4" focusers will have a fine focus feature available in the future? Rich

Maybe that is the answer. We need to get Mr. Greenspan into astronomy and onto one of these AP waiting lists. That would probably put him more "in touch" with the needs of the average citizen:-) I

So many telescopes and only one Roland. Wouldn't Christine like to learn how to figure lenses in her spare time? ;-) Rich 6"

Oh oh, Marj could be a problem.... :-))))))))

However, Did not AP customers vote with their wallets along time ago about focal length?

pleased. I'm sure you could sell both focal lengths. I think the imagers have had sway for far too long. Rich

My AP 180EDT f/9 was $5995 in 1996. How much more would a 180mn f/9 or f/8 be using FPL53 only five years later? Unless someone is just taking the view of all the traffic will bear. I do like the

I soon as I get my 4" you can start on the 7" <<<ggg>>> Gilles 6"

Forgot to mention, I vote for the F/7, all the way!!!!

Roland, I can't directly answer this, but your question sounds encouraging? If you did decide to manufacture a larger refractor, the 7" is only slightly larger than what is now in your product

I concur. I am already on the list. Please advise on the delivery date. ~`8^)

Colt, You are right, there is a market out there for high-end scopes. For example, concerning RCOS scopes, The price range for RC's is 10K for a 10" to 40K for a 20" and they are selling! I think

What would be the difference in the manufacturing cost between a 7" triplet and a 10" MC? Rich

Roland, would feel better if you were asking about the price of a 7" f/8 or f/9. Rich

Hi Roland, $12-15K would be nice. I think that is what similar new 7" refractors are going for. But would this allow you a good enough profit margin? Please put me on the list if I'm not
