Bruce-

My recommendation would be the A-12. It’s pretty simple – the “averaging” device in particular – and it can be used in 2 modes: 1) for shooting the sun, and 2) for shooting faint stars. The latter is really nice because it has a huge field of view, so you can easily recognize the constellation. There’s also an restoration manual on line which has a ton of pictures, and one of the NavList members (Bob Swartz) is super knowledgeable in case you have questions.

The downside is that the bubble chamber has a fixed bubble size, and is a pain to refill (although there’s an easy modification that makes it much easier) so it’s nice to have two chambers with different sized bubbles. #16 looks like it might have two chambers (there’s one in the “spare” slot of the case) so I would inquire about that one. Also make sure it doesn’t have old batteries rusting inside the unit – I can attest to how difficult it can be to clean those out!

I’d love to hear what others have to say on the choice. I’m not too familiar with any of the more complicated ones.

Garret-

 

Take a look at the collection Mark Sudbury inherited. He has a MK1XA for sale – I’m not sure is that is close enough.

p.s. I’m curious – why the MK1XB? I bought an A-12 about a year ago because I wanted something simple that I could restore (which it is – to a fault). What is it about the MX model that interests you?
