NGC2264 Cone nebula

The Cone Nebula is a molecular cloud of excited hydrogen gas, located in the constellation Monoceros. It belongs to the group of nebulae, which can be observed/photographed during the winter in the northern hemisphere. I tried to capture this object a long time ago without success. I must say, it’s a very difficult one, so I attempted this time with new equipment. Specifically new extra, super, mega narrowband filters, having a bandwidth of only 3 nm. Combined with a small 6″ Newtonian telescope I was able to generate a pretty decent picture.

Here is a fake Hubble palette edit:

And here is a more natural-looking bi-color edit:

NGC2237 Rosette Nebula

A second deep space object, on which I tested the combination of Canon 6Da with WO RedCat was the NGC 2237 Rosette Nebula (a short description can be found in my previous post). The field of view of this telescope, combined with a full-frame sensor of 6Da is huge. The Rosette on the left can be simultaneously captured with the Cone Nebula NGC 2264 (on the left). I simply love this scope and I cannot wait to test it under the dark sky in broadband.

NGC2264 Cone nebula

Cone nebula is a giant cloud of ionized hydrogen gas, which includes the Christmas Tree Cluster. It’s located between two bright winter stars Betelgeuse (constellation Orion) and Procyon (Canis Minor) and it’s 2700 light-years far from the Solar System. There is a famous picture from Hubble Space telescope of the tip of the cone – star forming complex.

Bi-color picture didn’t look as I expected, therefore I decided to publish only mono version of hydrogen alpha channel.
