Hi Steve,

Wellll, this is kinda an apples and oranges comparison. Double stacking etalons (i.e. the Lunt 75mm) narrows the bandpass, but just as in night time viewing aperture rules. Narrowing the bandpass allows for higher resolution "surface" details, but not proms. By going to a larger aperture (i.e. the Lunt 152mm), you get increased detail and higher resolution. I would go for the 152mm Lunt if money were no object. When you win the lottery you can then double stack it!! 8) YMMV and others are sure to have a differing opinion.

I second Steve's vote to go with the larger aperture.

Clear, sunny skies.
