stunning object photographically, this scientifically interesting
region contains the star cluster NGC7129 off to the lower left
of the image, the blue reflection nebula NGC7133, a stunning
yellow reflection nebula LBN497 just below the bright blue core,
and topping it off, the deep red small nebula in the field are
Herbig Haro objects.
This kicks off the new
shooting season, the past two or three months of heavy monsoon
rains and dense clouds have made it impossible to do any CCD
imaging here in Arizona. Now the storms have cleared out, the
spectacular falls skies beckon!
