While you're here, how about checking out the Astronomy Book List ?

Gene - Doc G - et. al. .....

Thanks VERY much for this info on the bino viewers. Both my eyes are
relatively good, so it should work out for me. The thought of being able to
look at things with BOTH eyes in a relaxed way is very appealing to me. The
expenditure is very unappealing to me, but heck, if I wanted to be into
something inexpensive, I should have taken up collecting Pez dispensers or
something. After all the moola I've spent so far, this shouldn't hurt too
bad. And I already have a nice set of EPs around, including a few Radians.
The TV zooms are an intriguing idea as well. I'll check out the Tak bino
viewer and see what I can find out. Thanks again, and I'll keep you posted.
Now that I have confidence in collimating, I'll probably go for it. Heck, I
feel like my scope is really sharp now. I was viewing the Moon last evening
when it was still quite light out (6:30PM MST), and at 340x, I was a almost,
almost able to make out the little rille in the floor of Vallis Alpes. The
shadows just weren't quite right. I cranked it up to around 475x with a
2.5x TV barlow and I could still see very clear detail during good moments.
That satisfies me for now. I figure with a bino viewer I can, once and for
all, settle the issue of seeing the Apollo 11 lunar lander, along with the
elusive footprints. ;-))
