These are landscapes and skycapes at night, much like daytime photography but with much longer exposure times. The goal here is not magnification, as these are mostly shot with wide-angle camera lenses. The magic is time! Our eyes can only gather photons for a few tenths of a second, but the camera can sit there with its shutter open and let the light shine in. Shooting on dark moonless nights brings the Galaxy home, and by shooting with some moonlight we can juxtapose the cosmos with the local landscape.
These are all shot with an old Canon EOS 40D which has been modified by having the IR-blocking filter removed from the front of the imaging sensor and replaced with clear glass, letting the red glow of ionized hydrogen into the chip. I use a special body-mounted H-alpha enhanced ultraviolet-infrared filter (IDAS HEUIB-2) that prevents stars from bloating due to near IR light but lets the red H-a in. Some of these nights capes are done from a standard photo tripod, but exposures longer than 30 seconds require tracking with the Vixen Polarie. Nightscape imaging is much easier using a fantastic commercial program called BackyardEOS.
