March 13th - HAlpha and White Light


Recommended Posts

Had a good session around lunch time, after very thick mist for most of the morning, more misty up here at 800 feet than lower altitudes nearby and it lingered longer.

I've put on two HA pics, I think the one without proms is slightly better on surface detail.  Both single exposures, Lunt 60mm DS and  Olympus E-M5. The prominence version was taken at 11.59am, 1/15 sec at 400 asa and the other at 11.35am, 1/8 sec at 200 asa.  There were two filaproms on the E limb, one becoming the largest prominence and the other being a low extension of the almost circular filament adjacent to the limb.

The WL whole disk was taken at 12.14, Lunt H Wedge, Equinox 80mm ED and the Olympus.  For the closer view of AR2519 and AR2521 I also used a x2 barlow.
