David;
Sure, you can use it. The -2 still has the advantage of light wieght.
You'll use it on 'B' with a locking cable release. However, since the
mirror moving up when the shutter releases make shake the scope, you may
want to use an additional shutter techique. Called the 'Black Hat' in
astro-circles, what you do is, before you release the OM-2 shutter, use
a large black object (hat, matte board, etc) to cover the telescope
opening (but don't *touch* the telescope with the hat) . Then open the
OM-2 shutter, then remove the hat *after* any vibrations have died
down. This of course is limited to 'long' exposure, longer than the
shortest exposure you can accurately time with the hat. Oh, and don't
forget to again cover the scope with the hat before you release the
shutter.

PS, The OM-1 is better because it has mirror lockup. This will usually
eliminate the need for the black hat trick.
