M76, Little Dumbbell Nebula

The Little Dumbbell Nebula or M76 was discovered in 1780 by Pierre Méchain who reported this to Charles Messier the same year. It is a planetary nebula in the constellation Perseus. The nebula is about 2500 light years from Earth and has an apparent magnitude of 10. The bright part of the nebula is 42"x87", the wings 157"x87". The nebula is surrounded by a faint halo covering about 290 arc sec in diameter. This material was probably ejected at an earlier stage in the form of steller winds. The central star is of magnitude 16.6 and has a temperature of about 60 000 Kelvin.

The image was taken with 16" GSO Ritchey Chrétien telescope and QSI583WSG camera on a Paramount ME2 mount.

Exposure times were: LRGBH:5:3:3:2:8 hours. A IDAS LPS filter was used.

All images were taken in 1x1 binning.
