NGC 6914

NGC 6914 is a reflection nebula about 6000 light years away in the constellation of Cygnus. I shot this in R, G, B, Lum and Ha. I tried diffident ways of combining those masters and ended up combining the RGB and Lum then using a Masters of Pixinsight pixel math formula to add the Ha to the RGBLum. I know there is considerable discussion about whether to and when to use Luminance and Ha in the same image but I feel that the the Lum added some structure and the Ha definitely added depth. I did linear fit the Lum to the RGB image and I felt that was an important step in avoiding the Luminance wiping out the color in the RGB combination. I also used MLT for some sharpening with 7 layers plus a residual. It is important to keep that subtle but I feel that is a powerful tool , particularly on nebulas.

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.
