[ATM] Re: Amateur

["Rory Blake" <rory123@bellsouth.net>]

As amateur Telescope builders, we are all "newbes" in some aspects,
especially when we come up against something we have never seen before:
This time, I really do need your collective help because
I'm certainly a newbe when it comes to this one:

I've come up with a multi-coated apo stack of lens that I just don't know 
what to do with.
The aperture is 7 inches and the focal length is 3.5 inches.  That's right 
F/0.5.
The stack is mounted in an aluminum housing almost 6 inches thick.  Clear 
focus from corner to corner, wide angle, and color is perfect.  The mount is 
ultra machined and must have been very, very expensive.   Heck, Schmidt 
cameras are not this fast.  What could it have been used for?
More important:

What is the highest and best ATM use for such a fast light bucket?

Thanks,
