I'm interested in seeing how the Denkmeier Solar Spectrum 60 - PST upgrade works. It has a good writeup in the latest Astronomy Technology Today magazine. It looks like the current pricing for the upgrade is $599. Hopefully, some additional reviews will show up. It also appears that Denkmeier has a PST binoviewer product. There appears to be a bit of info here: http://deepskybinoviewer.com/index.cfm?fuseaction=category.display&category_...

For the last few years all that has been visible in H-Alpha is granulation it looks like an Orange and very uniform through out. Their have been no other surface features visible during this minimum. Prominences viewed from the top can be spectacular, during maximum prominences are everywhere not just on limb. I am reserving my judgement on PST until we are at maximum.
SLAS members are fortunate to have access to PST's and a .5 Daystar. The Daystar is more tuneable than the PST, although onband viewing is most pleasing to me. 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.

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.
