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 7293, The Helix Nebula ~4.5 hours of LHaRGB: Dealing with “Bad Data”

This was my second attempt to capture NGC 7293 - the Helix Nebula - located in the constellation of Aquarius. This time I had high expectations as I was using longer integration times, a longer focal length scope, and a new generation ASI2600MMPro camera. However - LOTS of things went wrong with this capture and its data came out pretty compromised! Some intense image processing minimized the impact of these problems - but the final image falls far short of my expectations. A good example of what can go wrong!

NGC 7293 - The Helix Nebula

NGC 7293, better known as the Helix Nebula, Caldwell 63 and in pop culture as "The Eye of God" or the "Eye of Sauron" - is a planetary nebula located in 655 light years away in the Constellation Aquarius. Planetary Nebulae are formed when an intermediate to low-mass star sheds its outer layers as it reaches the end of its life. The Helix Nebula is one of the closest planetary nebulas to the Earth, is estimated to be about 2.5 light years in diameter.
