Andromeda over Cape Byron Lighthouse

This is the Andromeda Galaxy over the Cape Byron Lighthouse, as it would have been at 3:58am on 20th July 2020.

Andromeda is about the same apparent length as the Small Magellanic Cloud, though much fainter and only visible to the naked eye under very dark skies.

The small magenta coloured patch to the left of the lighthouse is the Pacman Nebula, NGC 281.

Most of the sky consists of 53 tracked and stacked images which allows the detail in the galaxy to be brought out. The foreground is 10 untracked & stacked images to reduce image noise.

A separate stack of 7 tracked images was used to "patch" the sky either side of the lighthouse due to its lateral movement whilst the stars were tracked.

I used an astro-modified Canon 6D with a Sigma 85mm F/1.4 lens (at F/2.5) on the Star Adventurer EQ mount. All exposures were ISO 6400, 10 seconds. I manually triggered each image just after the light flashed (which has a 12 second cycle).

Sky images were stacked and pre-processed in AstroPixelProcessor. Ground images were stacked in Photoshop.

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.
