I am looking at options on the Skywatcher 102 and 120mm refractors and considering replacing the standard focusser with the Dual-Speed 2" Crayford Focuser .

Will the OTA need to be collimated after the exchange?

Many thanks.

Marty

Thanks guys. Back to the drawing board.

Hi,

I've been trolling the web trying to find an accurate reference with regard to the weights of the OTA Im interested in, but with little sucess. 

Does any one know the weights or can point me in the direction of these OTA.

Bresse 102S and 127S

Skywatcher Startravel 102T and 120T.

Mount options EQ3Pro or EQM 35Pro.

Thanks.

Thank you John, that worked.

Hi,

Have been considering the  Breeser 127/635 f5 Refractor on an EXOS1 Tripod.

Does anyone have any experience with either of these items please? Comments and opinions welcome.

Thanks.

Hi, very new to this site and following all the advice I tried the link to this resource. Only it takes me here
