I went with my family together with some members of the Astronomical League of the Philippines to Caliraya, Laguna t do some deep sky imaging. The sky was clear when we arrive and I use the opportunity to test some shots with the modified Canon EOS 1000D DSLR on the Orion constellation region. I was only able to do some short exposure only with the Canon EFS 10-22mm f/3.5-4.5 lens mounted on a Vixen Polarie star tracker as Orion was nearing the western horizon already. Nevertheless, test image looks promising as with a 3 minutes exposure, I could see Barnard's Loop, Orion Nebula, Horsehead Nebula, Rosette Nebula and the fainter emission nebula surrounding the head of Orion. I hope to give the emission complex of Orion some justice when November or December comes. After test image, I install the modded camera on the Canon EF100-400mm F/4.5-5.6 IS L lens to try to do some close up shots of big emission nebula that evening. With initial target Eta Carina getting clouded out, I turn my sights on M81/M82 galaxy pair with also Supernova 2014J still very bright on M82. Unfortunately, exposure was cut short as clouds started rolling in around 9:30pm and we got totally covered at around 10:00pm and we all thought it was game over for all of us that evening. Luckily, the sky started to clear up again at around 1:00am and totally cleared up at around 3:00am with the entire Summer Milky Way visible from constellation Crux till Cygnus with no clouds on sight! That time, I had to choose between shooting the Milky Way or Lagoon and Triffid Nebula but I opted to image the Milky Way instead as it was rare to see the entire stretch of it without any clouds :) We ended the session with a shot of planets Mercury and Venus conjunction just before sunrise. Overall, it was a good session for all of us :)

The Astronomical League of the Philippines, Inc ( ALP ) held its National Astronomy Week 2014 opening activity celebration at Manila Planetarium with several astro lectures as well as free public solar and night time stargazing session at SM Mall of Asia By The Bay North Wing. I was able to image the Sun at sunset with several large Sunspot groups visible without any solar filter. I was also able to image the waning gibbous Moon in the evening. Both objects were taken using Canon EOS 500D DSLR with Canon EF100-400mm f/4.5-5.6 IS L Lens.

The sky this evening is good. I initially try to test the 8" SCT for tomorrow use at National Astronomy Week but the collimation is real off so I opted to use my trusty TV-101 refractor again. I image the Waning Gibbous Moon (99%) through the refractor at full disk as well as test out the ZWO ASI120MM Webcam with the Televue 5x Powermate since the seeing looks ok. Although not that sharp because of average seeing, I'm still ok with it.

The sky tonight is hazy with fair condition. I proceeded to image the Moon with the ZWO ASI120MM webcam on my TV-101 refractor. I imaged some impact crater ray regions such as Tycho, Copernicus and Kepler. I also took some shots of Mare Humorum & Serenitatis region as well. Well, it's still a nice feeling to image the lunar features despite fair seeing condition.
The sky this morning is hazy with fair seeing condition. It's now getting harder and harder for me to conduct solar imaging session as the Sun gets block by the damn tall building in front of my observing window as the Sun rising azimuth moves toward the NE horizon daily :( My estimation is that it's game over for me comes end of February instead of usual mid May . After that, I will again be able to observe the Sun around mid August :0 AR11974 Sunspot Group is very beautiful and large group while both AR11976 & 11977 Sunspot Groups continue to grow in length & size. Hope yo be able to monitor its growth in the days to come.

The sky this evening is hazy and seeing condition is poor. I tested the modified Canon EOS 1000D DSLR on the Waxing Gibbous Moon through the TV-101 refractor. As expected because of the Baader filter replacement on the original Canon UV-IR filter. The image is reddish so I also posted another image of the Moon on what color it should be presented :) I also got to do 1 close up image of Schickard crater region with the ZWO ASI120MM with double stacked 2x barlow lens.
