BORG M75 to M75 Adapter

This should be the convenient for users who are using Series 80 configuration with 45ED(II), 60ED and 55FL. A main tube becomes really short in Series 80, especially with a reducer. This is the solution for people who are struggling short tube configuration.

The adapter has M75 male at both ends which allow to connect Series 80 tubes at front and back, and M57 female for the objective. See following example.

As shown, a front ring is clamped at the objective section without the concern of squeezing the objective lens. Unless a front tube blocks the objective’s field of view, you may use a longer tube too.

60ED(2260) can be connected directly. 45ED(II) and 55FL needs 7457 to convert the male thread. It is now available at $69.00 (part # M7575)
