H-alpha Sun – April 21, 2018

Scroll down to content

A lovely solar session today, in the woods around Targoviste. Good seeing but some technical difficulties…

Nevertheless, a nice active region (AR 2706) is giving us a very nice display both in white light and H-alpha light.

Equipment: TS 115mm APO F/7, Quark Chromosphere, ASI 174MM for H-alpha images. A. Herschel wedge was used for the white light shot. Seeing 6/10.
