so forgive the newbie comments.
loved the red dot finder on my celestron nexstar 114.
broke the piggy bank and got a nexstar 8
which comes with a 9x50 finder scope.
my small red dot finder
rarely lost alignment
and was easier to align (with 2 screws).
i really don't like the finder scope
as it seems like i'm always bumping it
and knocking it out of alignment
(just taking off the lense caps does it some times)
moreover i find it difficult
to realign in 2 dimensions with 3 different screws.
am i missing something here?
any hints on keeping the finderscope better aligned?
the screws are tight.
(i note that many in this forum like a finderscope and a red dot or telerad)
ok here's the trick:
lamenting the loss of my red dot finder
i was struggling to find a star
(had to crouch to see thru finder scope)
using non-dominant eye in finder scope
with dominant eye open to find star which wasn't even in the finder scope field...
the cross hairs of the finderscope
were superimposed on the star
even though the star wasn't yet in the finderscope field!
i slewed the telescope to get the star in the finderscope
and suddenly i see a second (brighter image) of the star
in the finder scope moving more rapidly
and in the opposite direction (right to left)
as the first image.
i lined the finder scope image on the cross hairs
and was all set.
holy corpus callosum!
my brain superimposed the crosshairs from the eye with the crosshairs, but no star onto the field of the eye with the star but no crosshairs.
is this the way one's supposed to use a finderscope
or just a fancy parlor trick?
in any event it seems to me that the finderscope can be used like a telerad.
maybe i'll give the finderscope a few more tries
but i still like the red dot better.
ps can anyone suggest a good forum for newbie comments like this?
