NGC 6914

NGC 6914 is the blue area in the bottom left of this image. It is a reflection nebula about 6000 light years away in the constellation Cygnus. I'm not sure why I framed it to be so far to the bottom left - probably should have raised it up a little but I guess I became entranced with the surrounding nebula. I find it interesting how important a good DBE is in Pixinsight and how tricky it can be with a dense nebula like this. I ended up using just a few (about 8) sample radius boxes with a size of 68 when processing this image. More numerous smaller sample sizes tended to wipe out some of the surrounding nebula. I find now that I must experiment with several different settings in DBE - varying the sample radius size, number of samples, location of samples, tolerance, shadows relaxation and smoothness. Each of those settings can make a big difference in the end product. I do not feel that I have a solid grip on all the subtleties of DBE yet but I recognise that I must take my time to get it right .

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.
