Question about lunt solar telescope

[KenGee (Kenith Gee)]

Hi All, Can people tell me their view on whether its worthwhile double stacking a 60mm pressure tuned Lunt with a 50mm unit.

I have a 60mm with the 1200 filter and I'm about to start imaging with it, a friend said that most imaginers used the double stacked version.

looking at he Lunt website it appears the double stacked 60mm has an additional 50mm filter on top.

Does the extra 0.2 narrow bandpass make much difference?

Kenny,
For imaging certainly yes!
For visual probably not. Some visual observers find the view through the double stack to be very dark - something you have to get used to.
The definition of the surface features are enhanced going from 0.7A to 0.5A with the double stack; not so much the proms - they're OK with the single stack 0.7A
I've used the Coronado SM60 filters single and double stacked on an ED80 for many years.
Which camera do you intend using?

Hi Ken,
Thanks I had planned to get a ZWO ASI 174MM Monochrome.

Kenny,
Good choice!
Enjoy.
