2017 / Narrowband / Nebula

Eastern Veil narrowband H-alpha with Esprit 100 triplet refractor and ASI1600MM-C

I’ve had more clear nights to use my new Sky-Watcher Esprit 100 triplet telescope. I’ve been collected HaRGB data between July 28 and Aug 7, on the Eastern Veil nebula NGC 6992.

NGC 6992 is one part of the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant (SNR). These are located in the constellation Cygnus, the swan, which is high in the NE at this time of year.

Due to focus issues I have to reshoot some of the colour data but I did put together this 2 hour narrowband image using an Optolong hydrogen-alpha (hα) 7nm filter.

My story began nearly 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.
