NGC 1499 "Central California" (Carl Weber)

NGC 1499 "Central California"

This image is the product of a perfect storm if you will of excellent weather conditions. During this imaging run, the city down below my location was experiencing some really thick Marine Layer type clouds. The benefit for me is that it blocked the sky glow caused by the city lights. It was so dark that my SQM reading was a 20.83. On top of that, the seeing was outstanding. I typically am in the mid 2's FWHM. For most of this data set the seeing was in the 1's and got down to my all time record of 1.3 FWHM. I wish it were like this all the time.

This is not my usual presentation as I decided to make it starless. I took the stars out during my processing and really liked how it looked. There was so much detail in the clouds, that I didn't want to clutter it up with star images.

The image is an HaSHO mix

137x300 sec Ha

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.
