Besides,
why do you care about the thread if you are unwilling to remove one?
***
Because
I want to put more bolts into the existing ¡°extra holes¡± to add a
Vixen rail.. But yes, I will try your suggestion and remove one from the middle
ring.. If my focuser and extension tubes are tight, it should stay put.. Nice
idea, Thanks!
Remove
just one screw, noting the tension with a precise instrument ¨C the human
hand.
Then
take it to a DIY or Ace store as suggested by one of our other friends. When
you get back to the mount insert that one screw in the ring and tension it as
much as you had before.
?
Since
the other two screws in that ring (not to mention the three in the other ring)
weren¡¯t changed the boresight (to use the proper artillery term) of the
guidescope won¡¯t have changed significantly.
?
The
difference in boresight alignment (main vs. guidescope) will be trivial, unless
you are trying to keep things within arc seconds. I know of no reason worry
about that unless you are shooting very long exposures with poor polar
alignment.
