This small but somewhat bright sharpless object sits in Aquila near the Scutum border. It has com nice structure that a larger telescope should be able to pick up. It also has a fainter amount of nebula with nice dark areas. The field of view in this image is 60x45 arc minutes and a wider view has really no advantage because there is not much around this object. It has an interesting boundary with a rich area of stars and an area where the stars are void. The nebula responds very well with a hydrogen-alpha filter and is mostly red. To colorize the nebula, you need to shoot a lot of color in the RGB even though the green and blue filters really only help the color of the stars. The oxygen III filter picked up nothing in 15 minutes so I don’t think this is a good object for a narrowband color image.

This nebula is ionised by the B1 II giant [F89b] S65 4, a star which is not yet in the SIMBAD catalog.

Russeil combines together Sh 2-65 and Sh 2-66. Both are seen at radio frequencies to lie at the edge of the massive W 43 complex. (Note that W 43 is believed to be twice as far away however, in the galactic bar region.)
