SH2-291 (Sharpless 291 ) Sh2-291 is a small object that is seen in the upper left area of this image. The brighter nebula in the bottom center does not have a catalog number but I think makes a great target for larger telescopes. This object seems to pick up some with the blue filter thus has some reflection in there. There is also red nebula all around in the image that picks up well with the red filter but is weak with the H-Alpha. Sh2-291 picks up very well with the hydrogen-alpha filter but does not do well at all with the OIII filter. This object also should do very well with a large telescope.
