H-alpha scope opinions?

With the Lunt 35 I believe the focal length is only 207mm. This means the diameter of the solar image will only be 2.1mm - with a 4mm blocking filter this is more than covered!!

You are of course quite right Merlin.

"Blocking Filter: 4mm; Full Disk Image up to 400mm Focal"

from CCTS Camera Concepts & Telescope Solutions :: Telescopes :: Solar :: Lunt Solar Systems Telescopes :: Lunt 35mm Solar Telescopes

I was thinking of the LS60 with a 500mm focal lengthwhich gives a ~4.5mm image
