Hello,

I have an Orion 80ED that I used for photography. I'd like to upgrade the factory single speed crayford to a dual speed.

Is this an easy conversion i.e., pulling it out and replacing or is there more to it?

I've seen different ratios out there like 10:1 8:1 11:1 any advantages of one over another even with manufactures?

Regards,

Ron
