Trifecta in Cygnus

This was a tough object for me to take on with a very bright moon, especially for the OIII data. I had no real signs of any OIII signal on the individual subs and I had to stretch the master to an extreme level to be able to obtain the required colour blend, although it is far from perfect. I took 130 Has and 122 OIIIs each at 3 minutes in length, which equates to 12 hours an 36 minutes imaging time. I also had the unfortunate issue of a slight focuser slippage in the Ha subs, which occasionally occurs, as I do not have an electric focuser. Shame, I have tried to compensate for this during the processing. Anyway, I hope you like the image, thanks and take care. Simon

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.
