Default refractor design

How does overall design of an OTA affect performance? Can you have
a top quality ED objective with a medium standard 3 or 4 baffled system and
still
get excellent returns? The light path is what matters. Should it be an
issue if that path
is passing through 3 baffles or 6 assuming that the interior of the OTA is
as black as you can get it?
And what about the focuser barrel? As long as it is of rack and pinion
design.

My point is, can you put a porche engine into a 73 volkswagon and still go
fast?

Your analogy is probably a good one. When you put a Porche engine in a 73 VW
is a car would have some pretty impressive straightline performance but that
would be all over the road, would not have enough suspension or braking to
handle the engine and in general just a road hazard.

Good optics requires good mechanicals to make them reach their full potential.

Default Air spaced Refractor Versus Other Techniques

I am thinking lately about making a Manwich spaced APO,
but not sure, there are many sauces and spices in Manwich ,
and should I add beef to lens or not?

I know Roland say "No beef in my lenses, no beef", but I
do not think he is spacing with Manwich, I think his lens
are Mazola spaced.

My friend says he can control his AP900 with PDA, like Palm Tungsten, but I cannot give up on my dream to control my AP1200 with my Intellivision. I think the Intellivision hand paddles are ahead of their time and the cartridge interface is perfect. I have crafted a series of 27 cartridges so far, which cover almost 30 objects in the region between Pollux and Castor.

You haven't explained why. I need to know why.

I think you need lithium real fast. Bipolar disorder has nothing to do with
polaris!
