B&W space, Winter 2014-15



As astronomical cameras are usually cooled grayscale CCD-cameras, color images are made by shooting each color channel through a filter. For broad band RGB images usually four filters are used Luminance and RGB-filters. Due to massive light pollution in my location, I'm specialized to a narrowband imaging, it's very effective method to shoot emission nebulae, since they are emitting light in well known wavelengths. All other light can be then filtered out and let just the right wavelength pass through. I'm using the most common combination of emission lines, a light from ionized hydrogen (H-alpha), sulfur (S-II) and oxygen (O-III).

The strongest emission line is usually the H-alpha, it has most of the details also. I'm publishing here a collection of H-alpha images from the Winter season 2014-15. Sometimes B&W images can be very beautiful.

Melotte 15, a new revision



I did some minor tweaking with the Heart nebula project.  This is a new version out of the 
Melotte 15 area at the heart of the Heart, IC 1805.
