Nice set, Pedro.

These are excellent Pedro, I think the SM40 offers the best on band view - the small filaments show most contrast (darker), and the small flux region mid disk is brighter, with more contrast with the SM40. Both are very even etalons though, I just think the SM60 sits a tad off-band compared to the SM40.

Thanks again Stu & Mark

I also think that the SM40 give a tad more contrast, However I prefer the SM60 (very even image)

Today I used another Pre-Meade SM40 and the TMB100/SM09II combo
