M42 Orion Nebula| September 2021

The M42 Orion Nebula is now visible in the early morning hours. While the sky is still generally cloudy in the Philippines in September, the Orion nebula is bright enough to be captured through thin cirrus clouds, even with the moon at 97% illumination.

M42 Orion Nebula imaged with a 4 inch f/9 refractor with 0.63X DIY focal reducer (now at f/5.65), a UV-IR filter, and an ASI 533 astronomy camera

Veil Nebula in Cygnus

A filter such as a dual band Oxygen III (OIII) and H-alpha filter inserted along the optical train lets the light from the nebula (and the stars) pass through, but block out everything else, particularly light pollution. This image was taken in Bacoor, Cavite in July 2021, with an ASI 533 cooled astronomy camera and a 50 mm f/4 Tamron lens (at 210 mm focal length), with 27 frames of 240 seconds sub-exposure, for a total of 1.8 hours of exposure, tracked and guided using a DIY tracker. Only light and flat frames were used in this image, no darks and bias frames. This image was stacked and processed in SIRIL.
