Question:

Can you help?  I have a 2″ eyepiece and want an adapter so I can fit 1 1/4″ filters to it.  I realize that my field of view will be restricted.  Do you have such an adapter?

Thanks, John

Answer:

John,

Because of the severe vignetting that would result, no one makes such an adapter. However, we know a way around it:

We do have a 2″ female, 1-1/4″ male eyepiece adapter (it allows the use of 2″ eyepieces in 1-1/4″
holders) which is threaded on the bottom for 1-1/4″ filters.

You would sacrifice over 50% of your field of view to use this adapter, but it is on our website,
part number 735-49020. It is usable with 2″ eyepieces that have shorter focal lengths.

Note: if using this adapter in a newtonian scope, it will require an additional 2″ of in-travel in the focuser to come to focus. With any catadioptric scope  having a moving mirror focus (SCT or MCT), it is  more easily  usable.
