This was not my planned target for the night. I was looking forward to the rare clear night to try to finish up my NGC 1333 composition. But, as luck would have it, about an hour into my session capturing R-filter subs on my ASI1600MM-Cool, I checked in on NINA and noticed a creeping dark "stain" on each of my subs

I quickly knew something (dew, frost?) was slowly running along my sensor window.

So, I shut everything down, took off my 1600 and checked the protective glass and, sure enough, a tiny streak near the edge of the sensor window. Determined not to lose a clear, weekend night of imaging, I quickly pilfered my ASI294MC Pro OSC off my EdgeHD 8 and slapped it on my ES127. I was up and running again in about 40 minutes. But, I decided to just shoot a new target and finish 1333 later. I eyeballed the sky and, lo and behold, the beautiful Seven Sisters were up high.

With that, here is my one-nighter with the Seven Sisters.

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.
