SH2-255 (Sharpless 255 ) SH2-255 is the small bright one in the bottom. Above is SH2-257, and SH2-254. The two smaller ones are SH2-256 and SH2-258. Not much here for a wider field of view but the larger telescope can define the structure very well. The nebula complex picks up best with the hydrogen-alpha filter. However if you do not have narrowband filters, you can capture a great RGB color image. The complex also picks up very well with the sulfur II but is weakest with the oxygen III. However, with a long enough exposure you can capture a nice color narrowband image. In this image Sh2-255 is the top nebula.
