Yes, I agree a companion guide would be perfect.
It would seem that S&T is missing out on a companion field guide opportunity. Sky Atlas 2000 has a companion guide. Pocket Sky Atlas should too.
I love the S&T Pocket Sky Atlas.
I have bought copies of it for friends as well. Makes a great gift.
I use it for all of my local observing, as there are 1500 DSO, and to be honest I'd be lucky to see 1/4 of them from our regular local observing site.
I only pull out the big atlases when I'm headed out of town to very dark skies.
But the PSA is limited as there is no information about the objects. A companion guide would be high on my list.
