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. This event hosted by the Astronomical League of the Philippines is by far the largest star party and astro-gathering in the Philippines.

A DSLR now serves as my dedicated camera for astrophotography, which may be used with typical camera lenses for wide-field shots of celestial objects, or may be mounted onto a telescope for closeup shots of galaxies and nebulas. Read more.
The modification involves physically removing the “hot plate”, a kind of filter that blocks infrared light. Manufacturers install it in cameras in order to correct for the reddish hue inherent to CCD or CMOS sensors. Removing such filter makes the camera more sensitive to IR and as well as H-alpha wavelengths, which is particularly useful in deep-sky photography.
Eyepieces are essential parts of a telescope. With different eyepieces, different zoom levels may be achieved. Eyepieces are interchangeable, and thus, may be used from one scope to another. It is always advisable to invest on a good one, since you may still be able to use it in case you have finally decided to upgrade and buy a new and larger telescope.
New telescopes are usually supplied with 2 eyepieces, one is ‘hi-power’, which will show zoomed-in views, great for close-up views of planets, the other one is a ‘low-power’, which shows zoomed-out views, intended for observing deep-sky objects. Below are eyepieces supplied in one of my telescopes:
Being in this hobby since 2003, I have learned a few astro-modification projects which you may also find useful in improving your current imaging setup. Astronomy need not be expensive! Even the modest do-it-yourself (DIY) equipment will produce outputs comparable (and I must say, in certain instances, better) to commercially available counterparts. The key to optimum performance is proper tweaking of your equipment. Feel free to browse through some of the DIY astronomy projects here.
