The Rosette Nebula or Caldwel 49
Nikon D5300A, Skywatcher ED80 + Baader UHC-S filter + 0.85x Focal Reducer/Corrector
Skywatcher EQ-3 Synscan, guided, ISO 800 2 mins x 40
Trying the Rosette for the first time, a fairly big but very dim nebula on the Monoceros Constellation. I spent many nights using Pixinsight LE to bring out the faint details. With a stock camera, it will be quite difficult to image this on a bright suburban neighborhood.
The Luminance channel extracted, image is rotated. Noise Reduction is not applied. Pixinsight has an excellent noise reduction algorithm. I'm more than impressed.
Here is a single frame at 2 minutes ISO800. Auto leveled. The Nebula is just so dim.
