4/2/2021 The Seagull Nebula

Thursday night I went up to the River Ridge Observatory to do some narrow band imaging. One of my targets was IC 2177 aka the Seagull Nebula in the constellation of Monoceros, the Unicorn. This is an emission nebula, meaning it’s relatively warm and glowing as opposed to reflecting light that hits it. What we can see here are the head in the upper left and the wings diagonally. Actually, I’ve always thought it looked more like a flying turtle than sea gull but either way he looks happy. This was made with my 11″ SCT at f/1.9 using a dual narrowband filter and my ZWO ASI294MC Pro. A total of sixty minutes integration.

4/2/2021 The Christmas Tree Cluster

Thursday night I went up to the River Ridge Observatory to do some narrow band imaging. One of my targets was NGC 2264 also known as The Christmas Tree cluster, the Cone Nebula, and the Fox Fur Nebula. Starting from the right, see that dark cone on its side? that is, not surprisingly, The Cone Nebula. Immediately to it’s left is another cone but this time a cone of stars with it’s peak almost touching the peak of that nebula. From this orientation, the Christmas Tree Cluster is on its side with its base being that brightest star in the middle. Finally, those swirls and stuff on the left make up the Fox Fur Nebula. These are all part of a common molecular cloud where stars are forming in the constellation of Monoceros, the unicorn. This was made with my 11″ SCT at f/1.9 using a dual narrowband filter and my ZWO ASI294MC Pro. A total of sixty minutes integration.

3/20/2021 The Flame and Horsehead Nebulae

Last night, under a first quarter Moon, I shot the Flame and Horsehead Nebulae in Orion with my C11 (Elf) with a dual narrowband filter at f/1.9 from the River Ridge Observatory. The dual narrowband lets only a few specific wavelengths of light through, those emitted by so called emission nebula, and works as an effective Moon and light pollution filter. At least as far as nebula are concerned.

This image was made from 12 five minute subs that were stacked and then processed in Photoshop. Orion will soon be exiting the stage for several months and I wanted to get this while I could.
