H-alpha Sun – September 16, 2016

A few shots in H-alpha light that present a small flare and an interesting prom on the limb. The small flare occurred in AR2592. The seeing was not good, but it did allow some images.

Equipment: 150mm F/8 Refractor, Quark chromosphere with UV/IR-cut filter, ASI 174MM.
