Why have I never seen this nebula imaged before? What a fantastic region!
Hanging off the top of Orion's club, this tight grouping of 5 objects from the Sharpless catalogue makes a superb grouping for the narrower field of view.
Moving roungly from left to right, we have Sharpless Catalogue SH-258 as the tiny faint mark on the left. SH-255 (IC2162) and SH-257 form the two bright spots. Then the tiny SH-256 resting in the bottom left corner of the larger diffuse SH-254.
The brightness of this region is shown by the relatively short 300s frames and 1.5 hours imaging time I used on this image. I hope to come back next season for the full 4 or 5 hours.
This image was taken back in the days when the homemade telescope mount didn't work very well at lower declinations, hence the poor star shapes.
I love this region of Sharpless catalogue HII regions and will be coming back in the 2012/13 season for sure!
