The Lunt Adapter for LS50/60FHa to LS50THa is a specific adapter to allow you to fit the LS50 or LS60FHa front mounted Etalons onto the smaller M80 thread of the LS50THa telescope. Although there is a dedicated double stack filter for the LS50THa, this uses a simple hinge to effect tuning. This moves the etalon away from the optical axis and can also allow dirt to enter. The LS50 / 60FHa is sealed and has a tilt mechanism which keeps the etalon on axis. It is therefore a better front stack although slightly more expensive.
M80 male thread one end, M90 female thread the other.

Mark, I know this is an old post but, if you still have this adapter (I suppose not) I'll be happy to buy it from you! I have a Lunt 50 and recently acquired a LS50fHa.
In any case, clear skies.
