Solar Imaging Session - December 21, 2014

The sky this morning is slightly cloudy and seeing condition is poor. I still proceeded to imaging the Sun. AR2241 and 2242 Sunspot Groups are almost the same appearance as yesterday while possible new AR2244 Sunspot Group is starting to grown in size and complexity. In Ha wavelength, AR2242 Sunspot Group has simmered down a bit after yesterday's X1.8 X-Flare. AR2241 Sunspot Group, on the other hand is staring to also getting to get active with some bright internal flaring. 2 nice large eruptive prominences can also be seen in the NE limb.

Solar Imaging Session - December 20. 2014

The sky this morning is slightly hazy but seeing was surprisingly superb! 2 dominant large sunspot groups AR2241 and 2242 are a joy to look at both in white light and in Ha wavelength. AR2242 Sunspot Group in Ha erupted a X1.8 X-Flare at around 08:27 (00:27UT) and coincides with my imaging of the group but unfortunately, the good seeing didn't last long and deteriorated tremendously while I'm imaging in Ha and clouds also interfered to end my solar imaging session.

Solar Imaging Session - December 12, 2014

The sky this morning finally cleared and seeing condition is very good as well. Lots of solar activities in the white light wavelength as AR2230 and 2234 grow in size and length. There is also 2 new sunspot group not yest designated yet but I guess it will later be classified as AR2236 and 2237. In Ha wavelength, not much high activity except for a few large dark filaments only. As I was starting to image in Ha, seeing suddenly drops from very good to fair thus I only image in wide shots only.

Solar Imaging Session - December 11, 2014

The sky this morning is cloudy and I had a hard time imaging the Sun! I had to image through passing clouds thus my white light images are soft IMHO. In Ha wavelength, the images are a little forgiving as lesser magnification. Overall, I'm still happy to have image despite the bad weather situation. :0

Solar Imaging Session - December 10, 2014

After more than 4 days of no solar imaging session due to typhoon Hagupit (Ruby), I was agan able to do some quick solar imaging session this morning. The sky is clear but seeing is fair only. AR2227 Sunspot Group has the largest umbral structure on the Sun right now with AR2230 Sunspot Group growing in size tremendously! Aside form another interesting AR2232 Sunspot Group on the eastern limb. there is another new AR2233 Sunspot Group emerging out of the SE limb worth monitoring in the days to come. In Ha wavelength, there are several beautiful large eruptive prominences visible int he eastern limb and AR2230 Sunspot Group showing lots of flaring activity inside its core.

Lunar Imaging Session - December 6, 2014

I was bored this evening and saw the Full Moon rising high already from the eastern horizon. I brought out my Canon EOS 500D DSLR with William Optics Megrez 90FD refractor mounted on a simple Celestron CG-3 mount and image the Moon. :)

Solar Imaging Session - December 6, 2014

The sky this morning is very hazy and I thought I wouldn't be able to image at all but sometimes patience is the key so after more than 45 minutes wait, the sky partially opened up for me to have ample time to image AR2222 Sunspot Group both in white light and Ha wavelength. Seeing condition though is not that good but was expecting worst :) In Ha, there is also a pair of moderate size prominences visible near the eastern limb.
