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.

Lunar Imaging Session - June 3, 2017

The sky this evening is clear so I want to image the Moon with my portable setup. Unfortunately, after I image the full disk, clouds covered the sky for me do any further close up shot of the crater region near the terminator. :( Image taken using ZWO ASI120MM webcam on Canon EF 100-400mm f/4.5-5.6 IS L lens set at 400mm f/5.6 .

Solar Imaging Session - June 2, 2017

The sky this afternoon is partly cloudy and seeing condition is very poor. There is a large eruptive prominence in the SW limb anda new AR2661 Sunspot Group in the eastern limb. Image quality is poor due to very bad seeing :( Anyway, as they say , better than nothing at all.

Solar Imaging Session - May 28, 2017

The sky this morning is clear and seeing condition is good. Unfortunately, the Sun is rising a bit to the extreme NE of my observing window and I got less than 10 mins of observing and imaging time left to shoot :( I estimate that my morning solar imaging session will come to end in a day or two as I will be totally obstructed from my observing window till maybe another 3 months except maybe on weekends where I will be imaging on the roof deck of our condominium area. Anyway, with that small imaging time left this morning, I was able to image AR2659 Sunspot Group nearing the NW limb as well as a long dark filament visible in the SE quadrant. There is some plage activity near the NE quadrant but I got obstructed already before I could take any shot. Nevertheless, I should still be happy to image at least 2 shots than nothing at all.

Solar Imaging Session - May 24, 2017

The sky this morning is cloudy and seeing condition is poor. There are 2 huge eruptive prominences visible in the eastern and NW limb. Unfortunately, I was only able to image the NW limb prominence as I got obstructed by the roof when imaging the eastern limb. I was also able to image AR2658 and 2659 Sunspot Group.

Solar Imaging Session - May 16, 2017

The sky this morning is hazy and seeing condition is again poor. Very hard to image as too many clouds. I just got to shoot through small openings on the cloud today :( The plage still doesn't develop into an active region but showing some flaring activity inside its core. There is also a huge eruptive prominence in the SE limb.
