Sky and Telescope’s Orion Nebula Series

SkyandTelescope_OrionNebulaSeries

To celebrate the end of 2015, Sky and Telescope (S&T) featured close to a hundred Orion Nebula (M42) photos submitted in their online image gallery–posting one random photo every hour until they have posted all the photos in the collection (started on December 24 and lasted until December 28, 2015).

Shown here is my M42 photos, as part of the S&T’s Orion Nebula Series.

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.

Deep-Sky Observing Marathon

The Philippine Astronomical Society will be hosting a Deep-Sky Observing Marathon on March 9-10, 2013, at Big Handy’s Grounds in Tanay, Rizal. Interested participants may kindly confirm their attendance with PAS Observation Chairperson Von Delelis (Contact: 09228320401). The Philippine Astronomical Society holds an annual stargazing session to take advantage of cloudless summer nights during months of March and April each year.

Philippine Messier Marathon 2013

The Philippine Messier Marathon Open is an annual star party conducted under the dark clear skies of Caliraya, Laguna, where astronomy-enthusiasts in the country gather to observe and meet fellow enthusiasts. The highlight of the event is the messier marathon — astro-enthusiasts attempt to observe and identify all the 110 m-objects in just one night. This year, the first wave of the event (there will be a series of stargazing events) will be on March 9, 2013, at Eco Saddle Resort in Caliraya, Laguna. Interested parties are encouraged to confirm their attendance in the Philippine Messier Marathon 2013‘s event page.

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.

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!

M57 Ring Nebula April 5, 2012

M57, the Ring Nebula, is a planetary nebula in the constellation Lyra. It is a cloud of cold gas expanding away from a small hot central star that provides energy for the gas cloud to glow. The nebula is relatively easy to find and is visible even with 3-4 inch telescopes. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 10 x 60 sec exp, IS0 1600.

M8 Lagoon Nebula and the Open Cluster NGC 6530 April 6, 2012

M8, the Lagoon Nebula, is a cloud of ionized hydrogen gas some 50 light-years in diameter, located about 5000 light-years away. It is a region in space where new stars form. To the east of the nebula is the open cluster NGC 6530, also visible in this photograph. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 2 x 240 sec exp, IS0 1600.

M20 Trifid Nebula and M21 Open Cluster April 6, 2012

M20 is a cloud of ionized hydrogen gas some 25 light-years in diameter. Dark lanes visible in 3-4 inch telescopes may be seen extending from its center towards the west, northeast, and southeast, effectively dividing the nebula into 3 distinct patches, hence the name ‘Trifid’ which means ‘split into three,’ was derived. M21, an open cluster, is also visible in this photo (upper left of the nebula). Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 240 sec exp, IS0 1600.
