The three images below show regions about 9' x 7' from the first
real SDSS imaging data.
These data are all from November 1998.
- NGC 2068 (M78) is a star forming region in Orion observed by the mosaic camera
on the 2.5 m telescope on the night of Nov 16 1998. The image is a composite
of the raw g', r', and i' frames. M 78 is a reflection nebula illuminated
by HD 38563 N, spectral type B1.5, the brightest of the three stars in the
nebulosity. The other two blue stars are of spectral type B4 and A0. This
star forming region is about 10^5 years old. The numerous red stars are
T Tauri stars. The position of HD 38563 N is 05 44 10.81, +00 04 19.1
