Description |
Jay McNeil, an amateur astronomer
from Kentucky (USA) discovered this new
nebula from his backyard using a 3" telescope after taking a CCD
image of the nearby Messier 78 emission
nebula. It is a probable eruption of a very faint star and occurred behind
a nebula known as Herbig-Haro 22 which is seen here as a "smoky cloud"
covering part of the bright new object. A number of other reddish
Herbig-Haro starforming areas can be seen, the most prominent near bottom
center. The nebulosity towards the top is part of NGC 2064.
The McNeil nebula strongly reminds of Hubble's Variable Nebula NGC2261
. North is up in this 10x15 arcmin field. |
