|NGC 3372 - Carina Nebula imaged by Michael Petrasko|
The Carina nebula is one of the largest diffuse nebulae in our skies. Although it is some four times as large and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known, due to its location far in the Southern Hemisphere. It was discovered by Nicolas Louis de Lacaille in 1751–52 from the Cape of Good Hope.
The image is a 15 minute exposure taken with a SBIG ST2000XMC One Shot Color CCD camera through a Takahashi SKY90 3" (90mm) Apochromatic Refractor (pictured left) provided by iTelescope.net. Processing was done with SBIG CCDOps software and Adobe Photoshop CS6. 3x5 images were stacked with 3 synthetic luminance images created from each color image for noise reduction.
One shot color CCD camera can provide interesting images (if processed properly with synthetic luminance images) just as well, if not better, than high-end monochrome CCD cameras that use Red, Green and Blue color filters.
