About this image

The Spider (IC417) and the Fly (NGC1931) are captured in this wide frame image alongside the open cluster NGC1907 (to the left middle of the picture).

The image is a result of 6 hours of data over 2 nights (Feb 2 and 4th) using narrowband filters. It turns out that there is very little Oiii so the image colour comes from Ha and Sii rendered in the HSO pallete to give the red/orange hues.
