Astro-imaging in Antipolo (March 29, 2014)

Astro-Imaging in Bosoboso March 30, 2014
Imaging the night sky in Antipolo, Philippines, last March 29-30, 2014 with fellow astrophotography enthusiasts. I was able to visually observe some Messier objects near Sagittarius, along with the Milky Way, which is now well-placed in the southern horizon at around 3-4 am. I will be posting  images soon.

M33 Triangulum Galaxy November 11, 2012

M33_PinwheelGalaxy_50mmf1.8_20sec,ISO1600
The Triangulum Galaxy (sometimes referred to as Pinwheel Galaxy) is the most distant object that can be seen with the unaided eye, approximately 3 million light-years from Earth. This wide-field image of the Triangulum Galaxy was taken with a Canon 450D DSLR and a 50 mm f/1.8 kit lens, ISO 1600, 30 sec exposure, on November 11, 2012 under the dark clear skies of Boso-boso, Rizal, Philippines. The low surface brightness of Triangulum Galaxy makes it an extremely difficult target to observe visually in light-polluted skies. Photo Credit: Anthony Urbano.

DIY Dew Heater

Passive anti-dew system (i.e., requiring no power like a lens/corrector hood) may be able to help but only up to a certain extent (it delays the formation of dew, perhaps for a few hours, but will not completely stop it). As soon as the temperature of the scope drops below that of the dew point, dew will start to form and you will have no choice but to end your observation early. Without an active anti-dew system (heating by using electricity), it is simply impossible to completely eliminate dew. In this article, I will describe how an inexpensive DIY dew heater could be constructed using nichrome wire as the heating element.

DSO-hunting under light-polluted sky

As part of the UP Astronomical Society’s 2012 Members’ Lecture Series, we hunted some DSO’s on April 20, 2012, at the PAGASA Astronomical Observatory in UP Diliman, Quezon City.

DSO Lecture UP Astrosoc
DSO-hunting with UP Astrosoc

We have successfully viewed the following objects in a severely light-polluted sky using only a 4-inch telescope!

M4 globular cluster, M6 (Butterfly Cluster) open cluster, M7 (Ptolemy’s Cluster) open cluster, M8 Lagoon Nebula (diffuse nebula), M20 Trifid Nebula (diffuse nebula), M21 open cluster, M13 (Hercules Cluster) globular cluster, M92 globular cluster, M57 (Ring Nebula) planetary nebula, M27 (Dumbell Nebula) planetary nebula, Albireo double star, Mizar double star, Cor Caroli double star, Coathanger asterism, and the Milky Way!

Veil Nebula

A 30-minute exposure with an OIII filter shows the fine thread-like structure of the Veil Nebula, a supernova remnant in the constellation Cygnus. The narrow-band filter helps cut through the severe light pollution in the city. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 4 x 480 sec exp, IS0 1600. April 15, 2012.
