Sharpless SH2-33

Revised Processing 8-22-08.

This was a challenge object for me – both to get any data and to adequately process. I’ve attempted this one a few times from downtown Roswell with no luck – to many lights and a lot of skyglow. It wasn’t until I tried from a great dark site in Georgia that I was able to get any data for this object.

Sharpless Sh2-33 is very dim reflection nebula located in the constellation Serpens – the raw 10 minute ccd images show a very small dusting of the nebula above the background. The nebula cast a light reddish hue to the surrounding stars. In addition to the main image I processed this to bring out the faint wispy glow of the extended object in the bottom lower corner of the picture.
