Hello All, ( Great site Mike)

After doing experimentation with my ETX-70 I have found what I believe
is the best view you can get out of the scope. Using other acessories
from my fellow club members, and my own equiptment I wanted to find the
best view I could get and maximize the scopes true visual ability. I
believe after 12 different observing nights that I've found the best
combination for this wonderful scope.  I tried many different
combinations of barlows with eyepieces and filters of all types also
that most will use the #773 carrying case  I also wanted to make sure
that anyone that would follow my advice and findings would not have to
lug a extra case around. The tests were conducted during 10 super clear
dark location nights and 2 super sunny days.

( I do not do reviews for profit, I'm very opinionated as you may
discover, the following is tests done by me to best utilize my scopes
potentials, I have no reservations whatso ever!!! I just wish to share
my ings.)
