This image was taken over two nights in mid-March with an ASI2600mm Pro through a Celestron 8" EdgeHD on an EQ6-R Pro.

The image comprises:

L: 73 x 60s
R: 30 x 60s
G: 30 x 60s
B: 30 x 60s

Total integration time was two hours and 43 minutes. The image was processed in Pixinsight and tweaked in Photoshop.

Arizona has been on the receiving end of inclement weather from California. This winter has been quite wet and cloudy, allowing for only limited opportunities for imaging. In the name of expediency (and to make the most use of the few nights I've been able to actually do any imaging), I've stuck to brighter objects so I could use lower total exposure times. Hopefully, the siege of bad weather will pass by the end of this month.

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.
