I finally obtained Coronado 90mm Solar Max. Its performance is better than I expected, and it feels like it's from another dimension compared to previous telescopes. Properly as high end H-alpha solar telescope, solar prominence expressed in high resolution and chromosphere are overwhelming. Main unit of the telescope is very heavy and I was concered about its mounting, but setting was smoothly done without any problem. It makes me look forward to observing solar activities for coming seasons. It was expensive, but I'm highly satisfied with it.
