Hey Chuck, why don't you post a photo of it? I'm anxious to see it. -- Joe
Here you are, Joe. The sun never came out of the clouds enough today to use the double-stack. Even when the cloud cover was thin enough to see sunspots, it was dense enough to kill prominence visibility and more subtle surface detail. Wayne Sumner dropped-by, and while he was here it was even too opaque for a white-light binocular view with Baader filters. Here's the stock PST, on a tripod. Good for low-power, quick views only. For higher-power viewing, I mount it on one of two GEMs, or an Orion Teletrack mount. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/PST001_zps7b2bf54... Here is the double stack etalon assembly. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/Doublestackfilter... And here is the double stack assembly mounted on the end of the PST. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/DSonPST_zps90dcc6... Once I get some more experience with it, (and decent skies), I'll take some photos, maybe some video sequences. BTW, even though he's moved-up to more sophisticated solar equipment, Bill Cowles has agreed to bring his PST double-stack etalon to Winchester Park on the 27th for the sun party, so we can try a triple stack on the PST. Should be interesting!
