Was checking my Lunt LS60 solar scope before use and noticed some blotching on the outside perimeter of the B1200 blocking filter { as you look in from the scope end}. Got in touch with Lunt to see if its still safe and if it's repairable etc, they were quick to get back to say its safe and a posting a replacement blue glass part . Anyway just a note to anyone with a similar scope check your blocking filter .
No visible degradation of views yet though, but in the email with the Lunt rep
it would in all probability get worse . Waiting for a return email on the procedure to replace the glass element. Scope is 2014 vintage.
