These data were taken at home in mag 4.5 skies. The 5.4 mic. pixels in the U8300 resulted in a plate scale of 2.1"/pixel.
Description
The Elephant’s Trunk Nebula (IC 1396A) is a 20 light-year long, dark globule within the emission nebula IC1396 about 3,000 light years distant in the constellation of Cepheus. The globule is a location of new star formation due to the presence of dense dust and the compression of gas from wind from the massive, hot O-type stars to the right. Many of these young stars and protostars within the globule were detected in infrared images and are not seen at visible wavelengths.
