This starless image of The Soul Nebula is work in progress, captured recently from Grand Mesa Observatory’s System 1 using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.

I’m not a big fan of starless images as a finished subject however I wanted to show you this as I often make my images starless as part of my post processing routine so as to reduce the star size and create more emphasis on the deep sky object. Up until recently I was using the stand alone version of starnet but now that Pixinsight have integrated it into their own software I find it much less time consuming and easier to use. I was so impressed with the starless image result on the soul nebula that I decided to share it. This orientation reminds me of a map of Australia where I grew up.

Captured over 4 nights in October and November 2020 for a total acquisition time of 20.5 hours.

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.
