The Shark Nebula in Cepheus
This predator apparition is composed only of interstellar gas and dust. This is my latest project, the Shark Nebula. Actually lots to see in this image including LDN1235, VDB 149, VDB150 and galaxy PGC 67671. It’s an interesting region of interstellar gas and dust sculpted by massive stars and their fast stellar winds and light energy. It’s located about 650 light years from Earth in the constellation of Cepheus.
This image was taken using the Starfield Optics 8inch astrograph equipped with a Starizona Nexus F3 reducer/corrector. A QHY268M cooled cmos camera was also used along with a QHY electronic filter wheel with Optolong filters inside; L-R-G-B filters were used to capture this data.
This cloud of interstellar gas and dust spans 15 light-years head-to-tail. It’s very faint and challenging to image from a city.

My story began more than 40 years ago looking up at the Moon with a small 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.
