M27 Nebula, a LRGB picture modified with Ha and OIII info.

Yet another M27 LRGB, NB version, why?

Well, because it's a summer astro photography target up here/in Denmark, and it's an relatively "easy target" to catch :-)

The M27 nebula picture is composed as a MasterLUM, RHa,GOIII,BOIII picture.

Exposures were:

Lum=52x30sec, R=20x30sec, G=20x30sec, B=22x30sec. Ha=6x300sec, OIII=7x300sec.

The Master Lum consist of Luminance and narrow band info. blended together.

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

Description: I went back to the M27 source material from 2018.
Just to show the different elements/sub-stacks that were made to make the final M27 color image at that time.
Stacks made and used:
"R->HaR, G->OIIIG, B->OIIIB, Ha, OIII, L, LHaOIII, RGB, LRGB.
5 pcs M27 variants of the LHaOIII-RHa,GOIII,BOIII type"

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.
