Eastern Veil Nebula | September 2021

First light image of a DIY off-axis guider OAG fitted to a Sky-Watcher Equinox 100ED using an ASI 174MM as a guide camera, imaging at 565 mm focal length (0.63x DIY focal reducer). This image was taken in September 2021 with an ASI 533 cooled astronomy camera and a ZWO duo nebula filter, for a total of 2.4 hours. Stacked and processed in SIRIL without calibration frames.

Western Veil Nebula | September 2021

First light image of a DIY 0.63x focal reducer fitted to a Sky-Watcher Equinox 100ED. This image was taken in September 2021 with an ASI 533 cooled astronomy camera and a ZWO duo nebula filter, for a total of 14 minutes, tracked and unguided. Stacked and processed in SIRIL without calibration frames.

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.
