Hi Paul
Alpine Astro have listed a Baader “4in1” towards the bottom of this
webpage. Here are the details:
Universal 2" Clamping Eyepiece Holder for Zeiss (M68), Astro-Physics (2.7"), Vixen (M60), and Celestron / Skywatcher (M56).
I'm not sure if your AP would be 2.7" or is male or female?
I have one of these 4in1's that I used on my Vixen ‘scopes.
Cheers
Dennis
