How does the tuning compare to a Lunt?
It's a metal push fit adapter with locking screws made by Coronado. The big difference between front mounted etalons is a very evenly illuminated field.

Pressure tuners (aka Lunt ) can have a central "hot spot" (not all...some are very good). Front etalon tuning is very easy, a variable tilt stage angles the etalon to shift the central bandpass.
