|Supernova Remnant - Veil Nebula - Eastern Loop
The Veil Nebula in the constellation Cygnus is a huge shell of gas expelled by a collosal supernova explosion 15,000 years ago. Only in the furnace of such an explosion can the
heavy elements like calcium, gold, and silver be forged. Without these elements, life on earth would never exist. Thus, we owe our very existence to the sacrifice of the
supergiant stars that burn so brightly but so briefly. Despite its distance of about 2,500 light years, the supernova may have shown as brignt as the moon for weeks, but neither
the Neanderthals nor Cro-Magnons left records of its observation.
This image above focused on the Eastern Loop of the Veil, combining luminence exposures of 30 minutes clear + 60 minutes Ha + 90 minutes red with RGB exposures of 30,
30, and 45 minutes, for a total exposure time of 4 hours 45 minutes. An ST-10XME camera was used with a TEC 140mm refractor.

The full extent of the Veil Nebula, and expanding
giant shell of gas, is shown in the image on the left.
This wide-field image was obtained through a 180 mm
camera lens, combining 14 red, 14 green, and 21 blue
exposures, each 3 minutes, for a total imaging time of
2 hours 29 minutes.
