The main purpose of this image was to experiment with dithering the data collection to randomize the sum of all noise instead of processing using dark and bias frames. Imaging conditions were not ideal and I only had 10 wind affected frames to choose from but good for the exersize.

I also used a new stacking method available in DSS which is called Super Pixel Stacking. It uses 4 RGGB sets of pixels as one "Super" pixel in the image. This way there is no interpolation of colors because the true color information is available. The finished image size reduces to 25% of the original. I did a comparison to my regular interpolated stacking method and found two advantages. Firstly there was no resolution loss but actually a gain in detail which surprised me. Also the colors were broader in range and richer in comparison also. All in all a good result. I did have some star elongation due to wind and coma issues.

I was quite pleased with the result and I thought it was worth putting up for comment. Ill be keento aquire a stack of 30 well guided images when conditions allow to see how far this methodology can take my imaging. Exciting stuff!!

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.
