M78

M78 is one of a handful of objects that I have not imaged since my early days in this hobby, about 15 years ago, when my imaging camera was a Meade DSI-C. Since the last target I imaged was a dim emission nebula that was a stretch for my current camera (a stock Nikon D5300), I decided that I deserved a "gimme" target that would be relatively easy to image with my rig. So, I decided to return, after a decade and a half, to M78.

M78 is the brightest of a group of closely situated reflection nebulae that includes NGC 2064, NGC 2067 and NGC 2071. All four of these nebulae are simply bright areas within the much larger Orion B molecular cloud complex, which is a vast star-forming region. M78 and the region immediately surrounding it contains 17 Herbig-Haro objects.

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.
