Sh2-232 (Great Pumpkin) with Sh2-235, Sh2-231, Sh2-233, and PK173+03.1

I initially captured Sh2-232 (Great Pumpkin Nebula) in Auriga as a time-filler since the Milky Way and most of the nebulae are already on the west side of the meridian by the time it gets dark -- and pickings in Feb/March get slim for nebulae after about 11:00 pm.

But it turned out to be a very interesting target! There 3 other nebulae in the frame (Sh2-235, Sh2-231, and Sh2-233; ordered from closest to Sh2-232 to the farthest away), as well as a planetary nebula (PK173+03.1) at the center of Sh2-232! There also is a misclassified planetary nebula, PK173+02.1 just below Sh-235, but it now appears to be an HII region (Sh2-235A) associated with Sh2-235 (see the PI annotated version). Sh2-232 itself has some nice dust lanes in it as well.

Of course, I had to process this one in the ‘Pumpkin’ palette since it’s, well, a pumpkin! 😊 If you rotate the image 90 degrees clockwise, you can see the Great Pumpkin much better.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
