Hopefully I'm not hijacking the thread but looking at Ha solar scopes around that $2k range
here I'm hoping somebody can shed some light on the differences.
Specifically why is a larger blocking filter better? (eg B600 vs B1200)
And what practical difference does pressure tuning make in these scopes?
Also would you get better views from a smaller aperture with PT vs a larger one without? (eg LS50THa/PT/B600 vs LS60THa/B600C)
