Our star really is looking good at the moment with lots of things to see! This shot is a 12 pane mosaic taken with the 70mm PST mod and 1.6x barlow with the DMk31 camera. This setup really pulls out the detail!

AR11711 Ha - 2nd April
Monster active region AR11711 really is a treat in all wavelengths. This was taken with the 70mm PST mod with a televue 2.5x powermate to take the focal ratio up to f17.5. This high power setup seems to take the not so good seeing conditions really well.
CaK Closeup - 2nd April
There is lots to see in this closeup of the active northeast quadrant of the sun taken with the 100mm frac at 1600mm focal length. My homebrew CaK filter seems to really like working at these longer focal ratios - maybe time to start consider operating it in a collimated beam?
CaK Full Disk - Monster Mosaic - 2nd April
I took this full disk shot in the form of a mosaic using the 100mm frac at f10. The original image is huge and well worth a look at on Flickr if your monitor is big enough...
AR11711 in White Light - 2nd April
Monster sunspot AR11711 is the star of the show on the solar disk at the moment. This was taken with the 100mm frac at 2000mm focal length, Lunt wedge, continuum filter and DMK31. The spot has developed a light bridge as it slowly decays...
White Light Full Disk 2nd April
One of my first for a while: taken with the 100mm @ f6 with the DMK31, Lunt wedge and baader continuum filter.
