M57, a LRGB picture (Niels V. Christensen)

M57, a LRGB picture

Acquisition type: Lucky imaging

Note 1. July-2019:

This M57 image is still categorized as "Lacking data", one of 20 pics, which I don't understand?

What is missing?

Here I have added a public dropbox link/ a Picasa HD view of some of the pictures from 2018 when I did the processing work. Please have a look, thanks,

HD images

The M57 LRGB frames/film sequences were quality sorted by Autostakkert.

More detailed exposure details can be provided if needed/requested.

CCDStack2 was used to do the LRGB composition.

Adope Photoshop CS6 used for the final processing.

A FFC was used to increase the FL. The M57 picture is shown as/in size 100%.

In DK CPH it's summer time, 25->30 degrees centigrade during daytime and the nights are bright.

My home build observatory is placed in my front yard/in the "red light" polution zone, have a look here,

Red Zone

Kind regards Niels

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.
