California Nebula


I have always wanted to image the California Nebula but was not able to do so mainly due to weather conditions and partly due to my equipment. Just by looking at its stats, I know that it is huge - more than 120'. Definitely not going to fit in the FOV of my scope. So, when my most awaited focal reducer came together with the H-alpha filter, its the first object that entered into my priority list to image. However, when we went out last night, doubts were in my mind if it was not yet too late to image it. The waxing quarter moon was also in close proximity. Another test of the H-alpha filter, I said to myself. It took more than a couple of tries to frame it. In this resulting image, I made 25 frames of 4 minutes each.

Second Light of H-alpha filter


After arriving from a tiring trip abroad, I managed to test again the H-alpha filter on the Rosette Nebula. This time I tried to increase the exposure duration to 120 minutes, my longest so far. It's amazing how much more details can be realized by increasing total exposure time.

First Light - Astronomik Ha filter


I was able to acquire a H-alpha filter with the help of Mr. Brian Davis who hand carried it from the U.S. I was thinking that somehow I can take advantage of the few clear nights at home to do a bit of astrophotography. The sky at my place has been affected by ever increasing light pollution from nearby Pasig and Makati cities. Last night, I was pleasantly surprised to see that there was a break in the clouds. I hurriedly finished my dinner and began setting up my gears. I inserted my new Televue field flattener and pop in the H-alpha filter inside the Canon 350d. What better way to test my new toys than use it on the Flame & Horsehead nebulas, I said to myself. Also, I would like to test a new guiding software, GuideMaster. And so I snapped 15 frames of 240 seconds each. However, my luck ran out when the camera battery got discharged when I was about to shoot the dark frames. Anyway, the objective of this exercise was just to test the equipment and not image processing so I stacked the 15 images and here's what I got. Hmm. .. makes me want to set-up again. . .

New Year's Day Lunar Eclipse


After fighting drowsiness, I managed to shoot some images of the partial Lunar eclipse from our home in Taguig City. I started the first shot at 2:53 a.m. and every 10 minutes hence until around 4 am. I stacked the seven images in sequence to show the outline of the Earth's shadow on the lunar disk.
