Object name: NGC1907
NGC 1907 is the open cluster "companion" to M38. I was surprised that my short exposure time picked up nebulosity around the cluster. Of course, there's quite a bit in Auriga where the cluster resides. Still, it isn't seen often with the cluster, especially in short exposures like I usually take. Both the H alpha and a small blue reflection nebula surprised me. I picked a star cluster to image this night due to the transparency being poor for going faint. I expect this nebulosity would be rather bright on a good night. So why is it rarely seen in images of the cluster? Is it processed out as a gradient?
