Solar Imaging Session - September 7, 2017

The sky this afternoon is clear but seeing condition is fair. In Ha wavelength, AR2674 and 2673 Sunspot Groups are nearing the western limb and still producing some active flaring activities on its cores. In white light, AR2674 and 2673 are still a joy to look at and image. Hopefully , I can still get another chance to image them both again tomorrow before they exit the western limb.

Solar Imaging Session - September 3, 2017

The sky this afternoon is clear and seeing condition is very good. AR2674 Sunspot Group is impressive both in white light and in Ha wavelength. There is also a nice huge eruptive prominence in the NW limb.

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.

Solar Imaging Session - June 25, 2017

The sky this afternoon is clear and seeing condition is good. This is the first time that I will be doing solar imaging as well as any astro imaging at the roof deck of our condominium. Since the roof deck is a bit high at 23rd floor, I was expecting to have les heat turbulence from the neighborhood roofs and true enough, the seeing is much better than what I had in my previous old place where I can only do solar imaging at the window of our house. Since I haven't totally sort out all my astro stuffs, I only use a modest solar imaging setup with my Canon EF 100-400mm f/4.5-5.6 IS L lens and a Daystar Quark Chromosphere Ha Filter mounted on a Nexstar goto altazimuth mount. Although the seeing looks better, now I had to fight strong wind which shakes the flimsy mount. I guess after I sort everything out and can use my beefier GP-DX mount, I think I can also use the larger TV-101 refractor once again hopefully in the weeks to come. I also enjoy the company of my son this session and we got the bonding time to observe and image AR2664 Sunspot Group as well as the huge hedgerow prominence visible in the western limb.

Solar Imaging Session - June 4, 2017

The sky this morning is clear after a short rainfall while seeing condition is fair. AR2661 Sunspot Group is growing in size while fading AR2660 Sunspot Group is still visible in Ha wavelength. There is also a faint large eruptive prominence in the eastern limb.
