This is the current generation straight-through 9x50 finder sold by Celestron with its SCTs, mine came with my C14. Since I already had a finder this one got drafted into service on my small Newtonian; but I'm getting old and went for a right angle finder. The Celestron finder is in good shape. As with most finders the focusing ring is on the front and you'll have to focus it for your eyes.
I have seen M81 and M82, M27, M71, even M51 and other Messiers through this finder on dark nights so it is a "respectable" instrument to have on your larger scope.
Price includes USPS priority mail CONUSA shipping. Money order preferred but will take a check from a well rated astromart user. This finder sells on Astronomics for $60.00 plus shipping (say $8) so at $45 including shipping you're getting a very reasonable deal.
thanks for your consideration,
