This is another test image of the 16" RCOS at Swan Reach Imaging. This time it is of the planetary nebula called Shapley 1.
The image has nearly 21 hours of data with the majority coming from narrow band data. Some of the outer halo can be seen in the image.
I think overall the resolution looks quite good when compared to other images taken at near sea level. It even looks quite good against the Chart 32 image of the same target.
