A quick look at the overview images in CaK & Ha - taken only a few minutes apart - a comparison of the prominences is "interesting", they're very similar except that they're much better rendered in the Ha version - more aperture, narrower bandwidth, camera more senistive at Ha than CaK.

0905 UT. Coronado PST CaK, prime focus, DMK41

0912 UT. Solarscope 60, 0.5x focal reducer, DMK41

Interesting proms, not a lot of action on the disc ... more detailed images to follow later (hopefully)

Transparency very good. Seeing poor with smearing & substantial boiling. Temp 19C, wind NE force 1-2.
