Thors Helmet, a Hubble palette, stars RGB color image, CPH, Denmark

Like the Sombrero Galaxy M104, the Thors Helmet nebula is standing very low in the horizon seen from the Copenhagen, Denmark location.

I can only get around 1.5 hours of exposure each night.

This hubble palette, stars RGB color image, consist of subs taken during 3 nights, 10-12 & 13. Febr-2021.

The outside temp. these days were app. minus 4 -> minus 8 degress C, it was a cold and freezing ... :-)

The Hubble palette data, i.e. SII, Ha & OIII exposures were like this in total: 36x120sec + 38x300sec.

The Stars, RGB exposures were like this in total: 32x60sec.

Subs was only calibrated with master dark frames.

My home build observatory is placed in my front yard/in the "red light" pollution 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.
