Jellyfish Nebula, Dean Salman
Taken with MakNewt 8 inch F/4 astrograph using the SBIG ST-10 XME CCD Camera. I used narrowband filters: Sulfur II for red, Hydrogen-Alpha for green, and Oxygen III for blue to map colors. Total exposure increases with use of narrowband filters; 14 hours over 10 nights; CCD Commander automated imaging.
