M45, the Pleiades, 3 hours of total exposure with the ASI 1600MM. I was expecting the stars to be all bloated (isn’t it usually the case for Alnitak with this camera?) but they turned out fine. There was about 80% humidity that night (never seen that before in Nevada) and the scope was all wet…

I don’t have a dew shield or dew heater so I believe it affected the image quite a bit. I’ll probably try again another time when it’s dry as usual.

I imaged this target 3+ years ago with my old Canon t3i and I feel like there was more detail in the nebulosity, but the overall image wasn’t as clear.

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.
