M3 Globular Cluster

This is a test to see how good the Signal/Noise can be using dithered 90s subs on my new Aluma AC4040 camera and using an SBIG AO-X. Using the Pixinsight Signal to noise routine to quantify the images, I first stacked the RGB Subs (30,40,36 frames) using WBPP with weighting set on Cluster. I then drizzle integrated each color master. A Synthetic Luminance was formed by integrating the R,G,B drizzled masters with noise weighting, no rejection. The Synthetic Luminance was then deconvoluted, and then MLT linear noise reduction was applied. Here are the results.

WBPP Automatically picked 90s Reference Frame SNR: 3290

Synthetic Luminance Frame SNR: 25320

After Deconvolution SNR: 40910

After MLT Linear Noise Reduction with Linear Mask SNR: 95890

OK, the camera can produce details at short exposure for broadband frames.

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.
