Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

NGC 7822 - The Central Portion of the Question Mark Nebula (~14 hours in SHOrgb)

NGC 7822 is the Clamshell Nebula - located 2900 light years away in the constellation of Cepheus. This is a very large target, and with my smallest scope, I could still only fit the central portion of this complex area into the camera's field of view. This image results from just under 14 hours of integration and consists of a mix of narrowband data for the nebula and broadband RGB data for the stars.

SH2-119 The Clamshell Nebula (3.5 Hours in SHO) - An Unintended Image

My second image of the year started as a disaster and motivated me to move to NINA. I spent a few nights learning NINA during the bright Moon cycle, knowing the subs would be a waste. Lo and behold, there was an image there!

This is SH2-119—The Clamshell Nebula—3.5 hours in SHO. Read the story of my trials and tribulations that led to this image!

SH2-82 - The Little Cocoon Nebula - 7.3 Hours in LRGB

My first image of the year - and my first image from my new home after the move!

This is SH2-82—The Little Cocoon Nebula—7.3 hours in LRGB. Located ~4,000 light-years away in the constellation Sagitta, this emission/reflection nebula is in a rich region of the sky with a multitude of stars and dark dust lanes.
