The brighter nebula on the right side of this image is SH2-90 while the dimmer SH2-89 is on the left. This nebula also shows some nice structure around it that a large telescope can take advantage of. The nebula is fairly bright and picks up with both the hydrogen-alpha filter and even a red standard filter. I took an oxygen III image but did not pick up anything; however, a larger telescope may have better results. Creating color image using some of the H-Alpha will be easy to do since the green and blue did not really pick up anything.
