Combination of 50, 5 second exposures, SBIG ST9XE CCD camera.

Situated near the tail of the Scorpion, not far from the star Shula (the end star in the sting) are two little known nebulae which are easily visible in an 8" telescope. Shula is the brighter of the two stars in the centre of centre in the above image. The northern of the two nebulae is NGC 6357. The southern one is NGC 6334, also known as the "Cat's Paw" nebula. The bright nebula to the lower right in the tail of the scorpion, is IC 4628, while the very large but faint nebula at the centre top of the image is Sharpless 2-13.
It is interesting to compare the above image, made using an H-alpha filter, with the one below of the same region, that is unfiltered. Even though the above image had problems with clouds, it still shows far more then the image below. Clearly showing the benefits of the narrow-band filter for wide-angle imaging.
