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!

IC 2177 - The Seagull Nebula in SHO - with just 2 hours!

IC 2177, better known as the Seagull Nebula, is a rich HII emission region located 3650 light-years away located new the borders of the constellations Canis Magor and Monoceros.

This image results from slightly over 2 hours of narrowband integration on my 400mm wide field scope. This short integration time results from bad weather and sky access limitations due to trees on my property.

Careful processing was able to produce a reasonable image despite the lack of integration time.

NGC 2359 - Thor’s Helmet in SHO ~only 2.5 hours!

NGC 2359 - Thor’s Helmet - is my first image of 2022. This image is the result of 2.5 hours of narrowband data - limited by weather and the fact that this target is very low in the sky for me and access is very limited each night due to trees on my property. I had hoped to gather more data but at this point, it is now too late in the year. So my challenge was to see what I could do with such limited data. detailed processing strategy and log provided!
