Exceptionally clear sky in Tagaytay last February 24, 2012. The blue-orange hue that characterize a 100% cloudless horizon extends 360 degrees in all directions. For related images, click here.

The Gallia asteroid occultation expedition last October 2010 is research project in collaboration with NASA Johnson Space Center Astronomical Society, the International Occultation Timing Association, and the Philippine Astronomical Society. For the full observation report, click here.
Barlow lenses may be used to magnify images in casual visual observation and also astrophotograpy (afocal, prime focus, or eyepiece projection)
I find Barlow lenses very useful in achieving better image scale in planetary imaging (through afocal, prime focus, or eyepiece projection). Using a 2x Barlow lens, I can actually double the effective focal length of my setup. With a 2x Barlow, the effective focal length of my 900 mm telescope would then be equal to 900 mm X 2 = 1800 mm. During nights of steady seeing and I wish to further magnify an image, I use another 2x Barlow, thereby having an effective focal length of 900 mm X 2 X 2 = 3600 mm :)
Venus February 3, 2012
Image of Venus taken last February 3, 2012 at the Manila Observatory Roofdeck, captured using a 4-in f/9 refractor and a Logitech 4000 web camera with 2x Barlow at prime focus. The planet Venus is now on its gibbous phase. Photo Credit: Anthony Urbano
