H-alpha Sun – September 9, 2016
A short session today with AR 2585 in H-alpha. Nice to see the group is getting closer to the limb and it’s still in one piece. Hopefully it will get more active in the next couple of days and perhaps release a small flare 🙂
Equipment: 115mm F/7 Refractor, Quark Chromosphere with UV/IR cut filter, ASI 174MM. Seeing 6/10. For the solar mosaic (four frames) the 0.5x reducer was used.
