Hi Fellow Observers, I'm wondering if anyone around can compare these two from experience. I was very pleased with the Coronado PST detail of prominences and coronal holes when observing through Chuck's scope, and will probably get one of these after the eclipse. Just out of curiosity, 'm wondering if the pressure tuner on the Lunt is worth the extra expense. My guess is (without understanding) is that the tuning enables the viewer to see different focal planes but with different focusing. My preference is maybe not to keep working the focus for different aspects of the sun. The learning curve with tuning and focusing the Lunt seems higher (with better results?). So I'm here to learn. Thanks ya'll for your time and expertise. Best, Shoshana
