Whizard nebula NGC 7380 - HSO - RGB stars

Revision title: 2e version - gradients by GraXpert

Whizard nebula – NGC 7380 - Ha-HSO-rgb

A series of nights with excellent visibility at the end of summer, too hot and too dry, allowed 18.8 hours of HSO and RGB stars to be recorded during 3 outings.

The HSO images are composed of views at 5, 7 and 10 min. The mounts last 10 minutes with an average error of less than 2 arc-seconds, not visible in the images.

In early and mid-October no need to heat the telescopes – no dew – very rare. On the other hand, I had to increase the capacity of the batteries for cooling the cameras – as I said: too hot.

Not very happy with my OIII layer, underexposed – needs to be completed. The rest suits me very well. The most difficult region to manage is the very bright core of the nebula, which is otherwise magnificent.

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.
