2” diagonal in Mak127

[Trentend]

Do I need an adapter to use a 2” diagonal (needed for denk binoviewers) in a skywatcher mak127? I’ve read a few threads about a mak to sct adapter but not sure how this would work once attached to the 1.25” focuser. Photo below shows the telescope side of my set up (OCS45 needs to enter the focuser but not sure how).

Think I may need these two items:

Hi Trentend, both the adapters you have tagged are correct & will enable you to connect to 2” accessories with your MAK127.

Your mak may allready have the SCT threads on it. Depends on the age of yours. Check to see if the rear thread is about 50mm and if so you won’t need an adaptor.

If your Mak have nonstandard 44.5mm thread (as mine have) ,you will need adapter to convert it to standard SCT thread, like this one :

Then use any 2'' visual back.

One of better ones would be this one, bcs it will secure heavy load of your bino :
