M27, a 2018 summer test picture

Note 1. July-2019:

This M27 image is still categorized as "Lacking data", one of 20 pics, which I don't understand?

What is missing?

The M27 Lum, frame sequence was quality sorted and stacked by Autostakkert.

28% of the 459 frames were used/selected to stack.

Just FYI, the Luminance stack is here, a dropbox public link, size 33%,

Color info. was taken from this M27 picture,

Adope Photoshop CS6 used for the final processing.

A FFC was used to increase the FL. The M27 picture is shown as/in size 25%.

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.
