Continuing my narrowband imaging, I shot this late June 2014. This is an area at the center of the summer time constellation of Cygnus the Swan.

This constellation rises high over head and holds a lot of nebulous regions that can be revealed in images especially when using special filters such the one used for this image, an H-alpha narrowband. This filter isolates a specific part of the light spectrum and allows the camera to capture theses objects which are mostly red emission nebulae. Narrowband images look greyscale though not colour.
Technical:
William Optics Zenithstar 71mm ED APO refractor with Flat6 .8x reducer/flattener
SBIG 8300M CCD and FLI filter wheel. Using Ha filter only.
Skywatcher EQ6 mount
Nebulosity for acquisition and PHD/Orion Starshoot for guiding.
2 hours total data.
My story began more than 40 years ago looking up at the Moon with a small collapsible telescope my Father had. Encouraged by my parents, who bought me my very own telescope, a 4.5″ reflector, I began to explore the night sky from my family home backyard. Today I do astrophotography from my home in Kitchener, Ontario and also with remote telescopes located in New Mexico and Australia. Some of my images have won awards and have been featured online and in magazines.
