>I'm surprised at the detail at only 200mm

The result of a couple of hours polar alignment ;-)

>Have you tried it with a 2X teleconverter?

As I stated in my previous message (Re: [OM] OT astrophotography - was
Zuiko telephoto fro astrophotography), I don't recommend it.

>What scope are you using for guiding?

A 6" Newtonian with a so-called German Equatorial mount (Bresser Pollux).
It has some sort of Barlow lens near the secondary mirror, in order to
achieve a more compact size. For guiding task, I use a 12.5mm
illuminated-reticle eyepiece with a 2x Barlow lens.
