Hi Frederic

The front glass is broken. I guess it is beyond repair

I so sorry for this, Pedro! I have fall down my LS35 and PST etalon too. Thanks [no religion please] they survived.

BTW. May I get this broken etalon for some further experiments?

I prefer a pre Mead etalon but I guess this will be hard to find
I am always wondering what the REAL difference between the pre-Meade and Meade etalons.
Can you, guys enlight me in this question?

Thanks

The front glass is juste an ERF Pedro, the etalon is behind and maybe intact :)

Thanks Valery

I can send you the etalon but it is broken. The ERF is intact. It is the front element of the etalon that is broken.

Send me an address and I will mail you the SM60

best regards

BTW I tried several Coronado SM60 & SM90 and the pre Meade models always produce better images
