Details:
Sun today was quite photogenic. Seeing conditions were very steady. There were 2 nice sunspot groups (3006 and 3007) plus a couple nice prominences. Sunspot 3007 was "sparkling" with Ellerman Bombs in a blue-wing image. My Quark h-alpha chromosphere filter is on-band at the lowest temperature setting. So to image blue-wing, I have to unplug the heater and watch the laptop monitor as it slowly cools down and shifts bandpass toward blue. Then, hit the record button at the right time! 120mm f/8.3 refractor, Daystar Quark Chromosphere filter, ZWO ASI174mm camera
