The OA4 is still the best deal out there. Far better than what Orion is
offering and I haven't even looked through it! The OA4 dob mounted is less
than $1000. It's going to cost you $1500+ to fully outfit the Orion scope.
Your done with OA for under $1000. Not only that, absolutely no color,
unobstructed views that will knock your socks off. And I've actually only
looked through a 92mm scope not even the full 4" OA!
