Hi,
Have not come across specific Coronado double stack 'etalon add on' advertised as such for SM3.
Can a SM2 60mm filter, which is generally advertised, be added to an existing SM3 70mm (single) making for a double stack?
Would this also require additional thread adapter? I think the actual solar part of the SM£ is 60mm.

Excellent James thank you.
Must start saving while still available
Don't know what to make of Coronado - hard to know what to do.

Re: SM2 etalon on SM3 single stack
The SolarMax II line is being phased out as far as I can tell in favor of the SolarMax III line. Meade isn't doing very well lately. I wish someone would buy Coronado from them. Celestron maybe? Coronado has a lot of potential.
Lunt would be an obviously good buyer in a way but it would remove a major competitor and competition helps keep prices down.

Re: SM2 etalon on SM3 single stack
Think Lunt are doing fine by themselves and yeah agree competition is absolutary necessary and driven by Lunt and Daystar.
From my posts on SC and CN, appears to be very few folk on the SM3 ladder.
Have to say, and I know superfulness, Coronado is a looker, anytime i've the Coronado is out people around me say wow
Never say the same bout my Lunt, which is far superior internally in my experience.
Optics rule suppose, both inside and out.
