Ah the old North America Neb!
Well why didn't you say so?? (never been good with numbers even if they're nice round ones like 7000)
Nicely captured! "pentax 200 mm" - Is that camera + lens? So you're telling us no telescope was involved...? What mount? (sorry for all the qns, I'm on the verge of trying out astgrophotografica for myself)
