Picture was taken on 8th of September 2018 in the central Europe in Austria at the border with Hungary.
I was waiting for Giacobin-Zinner commet and I made a 360 panorama. This picture is a cropped part from a whole-sky image.

NGC 6334 - The Cats Paw Nebula

In 1837, John Herschel discovered NGC 6334, or perhaps better known by its common name, The Cats Paw Nebula. It’s an emission nebula located in the constellation Scorpius. Its distance to Earth is 5,500 light years

I wanted to try something a little different with the data set that I have collected over the years on this object. In the RGB colour space, this object can be a little overwhelming with its strong reds. (note: just my personal tastes coming through) The strong reds result from the hydrogen rich areas that completely conceal many hot young stars deep within the nebula. In many cases, these stars are 10 times heavier that our sun and emit massive amounts of ultraviolet light. The surrounding hydrogen gas absorbs this light, which is then re-emitted as a deep red seen in most photos of this object.

It should be noted that this area is one of the most active stellar nurseries of massive stars in our galaxy.

Luminance, Red, Green, and Blue filters where used to create the base of the image. Narrowband channels consisting of Ha, SII, and OIII where added as support data to enhance textures and highlight many areas within this large gas complex.
While the colours may not truly represent the typical RGB colour image, it does highlight many interesting features within. I like the area that looks like a miniature version of the “Running Man Nebula” found near Orion. This can be located just above the area that looks like a shark fin (or Star Fleet Icon), just left from the centre part of the image. It has a slight bluish colour like a reflection nebula. (Zoom in to 100 percent)

Center (RA, Dec):(259.955, -35.874)

Exquisite image and one of the few that shows the reflection nebulae associated with this nebula. I wonder if one of the 'paws' is a supernova remnant?
I would love it if you imaged more planetary nebulae in the future! Would you be interested in a list of 50 unphotographed regions of the southern sky?

Well, by APOD's page this is silhouette against a crowded star field, this dusty cosmic cloud evokes for some the image of an ominous dark tower, a structure that spans almost 40 light-years.

This image was captured over two nights of extraordinary seeing during August-September 2018 at Tierra Del Sol, California. This is the San Diego Astronomy Association's dark sky site at roughly 3000 ft elevation about 50 miles east of the city.

This is one of the most amazing things I have seen! All that's missing is IC 1396 and Ou 4. :D

I love it, too. And I'd love to see Ou4 as well, but I think it takes a lot of OIII exposures to tease that one out.
