Horsehead and Flame Nebula

With a bright waxing moon promising to wash out any imaging opportunities I might get while I was off work, when a clear night did finally come along I used the time imaging open clusters at various exposures and ISOs. I hoped they would be be less effected by moonlight and I wanted to better understand exposing to get the best star colours.

By about 2am, I was ready to sleep and did a final check on the scope. With the moon now setting, Orion, which is usually behind oak trees to the south, had cleared the trees to the west and, although was not far from setting itself, seemed particularly bright despite being so low in the sky. Unable to resist, I slewed to the Flame and Horsehead Nebula.

I wish I could have stayed up long but settled for 6 x 5 minute exposures at 1600 ISO. I should really get more data,, but for so late at night, and such few exposures, I think this came out ok.

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.
