Erik, you can always make an effective comparison using just solar granulation or surface features- you don't need huge sunspot formations or prominences. This is always present, even at solar minimum. It's rarely, if ever, visible in the PST. The PST was designed around a price point. It's a cool little solar scope for the money, but if someone wanted to get a bit more serious about solar observation, I'd recommend the Coronado SolarMax 60, or a DayStar. Of course, you'll spend a lot more money! The PST fills the bill for me. On Wed, Apr 7, 2010 at 11:51 AM, <erikhansen@thebluezone.net> wrote:
To me it seems the PST came out after the last solar maximum. Their has not really been enough solar activity in H-Alpha light to really compare the performance of PST's vs Day Star.
