Description

The Vela Supernova Remnant is a large, f3.8 x5.8 deg , and faint object that was buried in a rich star field and difficult to image. It was made more difficult in that I had less than two hour a night to capture subframes before the object disappeared behind the roof of our balcony. The image consists of 98 subframes of 600s and 720s exposures taken on eight nights through Ha and OIII filters for a total integration time of 18.1 hours.
