See the Moon as never before with Sky & Telescope columnist and lunar expert Charles Wood. This 2-sided card is a handy companion to his ongoing series of articles highlighting the Moon's complex geology. The table on the back provides information about all 100 entries.
This is Sky & Telescope's newest "synthetic" version which combines the best features of the discontinued laminated and unlaminated versions. It's lighter, will not warp with dew, and will not show fingerprint smudges.

It's pretty much the only choice.Pros:

This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.
