The Orion Nebula

The Orion Nebula and Running Man imaged last night on 111915 from a stack of 63 subs from 1 minute to 2 minutes unguided exposures at a low ISO 100 setting due to moon being up almost 50 percent illumination. I was very surprised it imaged so well. I was not in a "dark location" and had to deal with a few flood lights from 1/4 of a mile away in the country. The temperature was well below freezing and my batteries were all freezing up along with thick frost crystals all over my OTA. I stopped imaging about 12:30 A.M. local time due to extreme cold at about 27 degrees and loss of mount tracking reliably. My powerful camera battery was draining fast in 3 hours which normally lasts nearly 6 hours. This was imaged with a Hutech Canon 6D camera attached to a Hyperstar III lens at f2 560mm. The scope is a Celestron C11 non hd converted for hyperstar. The mount is a Losmandy G11 Gemini II Mount. I used 8 darks, 7 biases, and no flats.

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.
