NGC7023

I have avoided this object for some time as I have trees to my north which encroach on high declination objects just giving me maybe a 4h window to image. Taken over several nights with variable conditions including some Moonlight. I took some luminance frames of 5s exposure at the start thinking I may need them so as not to overexpose the central mag 7 star but I didn't need them in the end as the HDR multiscale process in PixInsight did a good job in processing. Some residual colour gradients which have been hard to remove so you can mark me down on that one

NGC7023 actually refers to the open cluster within the reflection nebula catalogued as LBN487, the whole complex is some 3 light years in diameter.

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.
