M38 - IC417 Region
Emission / Reflection in Auriga
Uploaded 1/1/26

Deep images from our dark high altitude site in northern Arizona of the M38-IC417 region reveal a host of beautiful features in the winter Milk Way. The brilliant star cluster M38 is at top, just under it is the rich smaller open cluster NGC1907 immersed in a wreath of nebulosity. At the bottom is IC417 a richly pink colored cloud of hydrogen surrounded by a dim blue reflection component. And just to its left is NGC1930 a stunning mix of both emission and reflection nebula in a small package. Note that the entire field here (about 3 degrees wide) is filled with arcs and wreaths of pink and red hydrogen emissions.

The included "Context" Image which was taken simultaneously with the 5x wide field of the 135mm perfectly frames the entire nebulous complex. Note the round "Pumpkin Nebula" on the upper left.
