Very very good. I am curious - you say focal length is 1000, but how do you get there with a 2x barlow?

Sorry for the confusion, the native focal length of the scope is 1000mm, with the 2x Barlow 2000mm. The resized image was at 200% using the Mitchell filter in RS6 😉

This is the first 6" short tube I've had and often wondered how they get a long focal length from a short tube. There is a metal barrel at the end of the secondary mirror pointing towards the primary which houses a lens. I'm wondering if I took that lens out if it would make it a 500mm scope. The only other thing would be the focus plane and if I could reach focus if I took the lens out. If it could focus it would be a nasty f/3.3 scope and with heaps of CA I'm sure 😁 just not sure if it's a 2x magnifying lens.
