ADAPTER M54 MALE - M42 MALE 2mm

This adapter combines an M54 male thread and M42 male thread (T2) for an overall optical thickness of only 2mm.
On the M54 side, the adapter has an M48 x 0.75 female thread for 2" filters.

Among others, the adapter fits:

• ATIK EFW filter wheels

• Lacerta 2" Herschel prism

• Starlight Xpress filter wheels

• Focusers with female M54 x 0.75 thread

This adapter is not compatible with SkyWatcher focusers as they have a different thread pitch (M54 x 1).
