Solar Imaging Session - August 10, 2017

It's been more than almost 2 months since my last solar imaging session as the weather is very bad and add to this are busy working days and compound it further with slightly high blood pressure that prevented me from taking the bigger risk to be bathe on a hot afternoon :( But since the sky was clear this afternoon, I can't help myself but to try to observe the Sun even for a short session just to be able to capture AR2670 Sunspot Group before it exits the Sun's western limb in a few days. AR2670 Sunspot Group is moderate in size and still shows some some solar activity inside its core. I also was able to see a huge slightly faint eruptive prominence in the SE limb before I called it a day as I'm getting a bit irritated and drained from the heat this afternoon.

August 7-8, 2017 Partial Lunar Eclipse

After a short rainfall in the early evening, the sky cleared up for all to observe the Partial Lunar Eclipse from start to end. The Moon enters the penumbral shadow at 11:50pm Philippine Standard Time (PST)just before midnight and it enters into the umbral shadow at 1:3am PST. Maximum eclipse of 25% occurred at 2:21 am PST. It then later exit the umbral shadow at 3:18am PST. The Moon finally exits the penumbral shadow at 4:50 am PST. I use my trusty Canon EOS 500D DSLR on Canon EF100-400mm f/4.5-5.6 IS L lens set at 400mm f/11 mounted on Celestron Nexstar mount.
