Solar Imaging Session - April 27, 2016

The sky this morning is clear and seeing condition is ok. 2 new sunspot groups namely AR2535 and 2536 looks promising as showing a lot of activity inside their small cores. There is also a huge eruptive prominence in the NE limb. I wasn't able to image AR2533 and 2532 anymore as I'm in a hurry to go to work.

Solar Imaging Session - April 25, 2016

The sky this morning is clear and seeing condition is ok. AR2533 Sunspot Group continues to be quiet while AR2532 Sunspot Group is once again showing some signs of flaring activity after going quiet yesterday afternoon. There is also a new large group of eruptive prominences visible in the NE limb which might be a good area to monitor in the days to come.

Solar Imaging Session - April 24, 2016

I wake up late this morning and had to image the Sun past 10am at laundry area. I tested using a portable solar setup using Coronado PST-Ha mounted on a Nexstar mount. I plan to use this later in the Global Astronomy Month's SUNDay free solar viewing at SM by the Bay at SM Mall of Asia. So far the Sun took a while to drift out of field so I guess it is ok to use. AR2533 Sunspot Group is solitary and very quiet as almost no activity inside its core. As for the AR2532 Sunspot Group, it shows a little flaring activity inside its core but both are very small groups. Seeing condition is also poor.

Lunar Imaging Session - April 22, 2016

The sky this evening is clear so I just took a quick shot of the Full Moon using Canon EOS 500D DSLR with Canon EF 100-400mm f/4.5-5.6 IS L lens set at 400mm f/8 on sturdy tripod. 1/1000 sec exposure at ISO 100.

Solar Imaging Session - April 18, 2016

I wake up late this morning due to tiredness as had to wake up early in the morning to vomit some acidic juices from my stomach. Sigh. Anyway, I was only able to image in Ha wavelength as after I finish imaging in Ha, I got obstructed already by the roof :( I will try to see if I could image AR2529 Sunspot Group before I go to the provincial work trip. AR2529 Sunspot Sunspot Group looks like it had erupted again with another strong M-class flare earlier in the morning but I was able to capture perhaps receding flare already but it is still very evident. There is also a huge SW hedgerow prominence that resembles a shark fin from the Jaws movie :)
Just before lunchtime, I have a short time to image the AR2529 Sunspot Group in closeup white light. It is nearing the NW limb thus have Wilson Effect already. Seeing condition is also not good but one can still some nice details on the sunspot itself. Good bye AR2529 Sunspot Group. Thanks for the beautiful sessions with you past few days :)

Solar Imaging Session - April 17, 2016

The sky this morning is clear and seeing condition is again very good. AR2529 Sunspot Group is now nearing the the western limb and should more or less exits in 2-3 days. There is also a nice large eruptive prominence near the limb where AR2529 Sunspot Group is located. In white light wavelength, AR2529 Sunspot Group decays even more but is still nice to view though.

Solar Imaging Session - April 16, 2016

The sky this morning is clear and seeing condition is again very good. I was able to capture AR2529 Sunspot Group both in Ha and white light wavelength. The M flare in AR2529 Sunspot Group had subsided a bit but one can still see some remnants of the flare. In white light, it is obvious the group is starting to decay a bit compare to previous days.
