NGC7331 - September 2015 - Red Zone Denver

This is my first try at processing this particular set of NGC7331 data. I was a little heavy handed with recombining my luminance data into the RGB and covered over some of the natural star color. I tried to bring the color back by boosting saturation but, by that point, the only star color left to boost was in the fringes of the stars. I tried different noise reduction combinations but eventually decided on a "light touch", so there is still a measure of graininess.

The equipment used was a Stellarvue SVQ-100 refractor, a Takahashi EM-200 Temma 2 mount and a QSI-690 camera with Astro Don filters and either an SBIG ST-i or a SX Lodestar X2 off-axis guider.

The image was made with a little over 15 hours of light spread across Red, Green, Blue, Luminance and IDAS filters from urban Denver, Colorado. All images were captured semi-automatically with a set of scripts I wrote for Software Bisque's The SkyX running on my Macintosh. If you would like to try the scripts, they are freely available on the Software Bisque forum.

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.
