This is cool, Dale, thanks for calling it to our attention. I may do some experimenting with various Barlows and my inexpensive (non-Denk) bino viewer. The SS60 upgrade looks tempting, but it's pretty pricey for a single-object accessory, IMO, on top of the investment in the PST itself. I guess if you are really interested in solar observation, though, that's justification enough. On Mon, Apr 12, 2010 at 9:21 AM, Dale Hooper <Dale.Hooper@sdl.usu.edu>wrote:
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_...
