I ran out of patience waiting for the weather to cooperate....now the Moon is up. So I decided to post this HaRGB image without luminance. Not sure I will collect lum now...we'll see. I was surprised to find out that the galaxy is not my favorite part of this image, but rather the open cluster at upper right. I think the absence of lum has benefited star color, and the "cluster of grapes" structure in the cluster is intriguing. just how close are those stars together? My dark sky prevented the depiction of the intervening dust and gas that permeates this region of the galaxy. The battle against noise necessitated a darker than normal image. Maybe a bunch more hours will allow me to pick up some of the fine structures.

Heat was one of my biggest adversaries during this shoot, with nighttime temperatures between 25 and 28 degrees C. I could not achieve the -20 degree sensor cooling I normally use. In fact, the blue channel was calibrated using a -20 master dark while the best cooling I could acheive was -17. There didn't seem to be any detrimental effects.

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.
