Hi all, as the title says, "can you clean etalon, inside of lunt 60mm, also dust on objective and dust on erf of double stack filter. Or is it best left alone.

If it were me, I’d email Lunt and ask their advice on etalon cleaning.

A best guess is that it takes a surprising amount of dust etc to make a noticeable difference, at least that’s what myself and many others have found with conventional optical components.

My gut feeling is to leave well alone.

You can clean most optical components with the usual care, however unless the performance is being degraded, best to leave things alone.  On a Ha telescope you would probably only see dust particles on a Barlow or the blocking filter. If using a camera most likely on the sensor window.    🙂
