Whatever. I passed my findings along for anyone that wanted/needed the
information, after finding that a set of screws from Chris Heapy didnt
*begin* to work in my scope at all.
If anyone feels the information is incorrect, the solution is very simple.
Dont use it!
All I can say is, it isnt very difficult to tell the basic difference between
a screw that is less than one inch long, and one that is is over three inches
long.
I suggest that if there is any more discussion, it be out-of-group, because I
doubt everyone wants us to be debating how to tell how long a screw may be,
once it is in your hand. Especially since I have one of each sitting in front
of me.
My scope was manufactured in 93.

I dont want to remove my collimation screws but I took a few measurements.
1. - Collimation screw head to corrector plate .75"
2. - Corrector plate thickness at periphery of secondary housing .375"
3. - Inner surface of corrector plate to secondary mirror edge .18"
Total: 1.305"
The screws dont exit the rear of the secondary housing, so I assume that
they are less than 1.305" long. My 10" LX200 f/10 as manufactured in 9/97.
