Nebulae of Andromeda

The apparent diameter of a celestial object is the diameter measured by an observer at a specific distance from the object - in simple terms, it refers to how large something appears in the sky.

Obvious as though this may be, the apparent diameter of something in space depends on two factors; its distance from us and its absolute size. The bigger the object and the closer it is, the larger its apparent diameter. Our Sun and Moon have a similar apparent diameter and hence we are occasionally treated to perfect and spectacular eclipses from our viewpoint on Earth.

Apparent diameters are often expressed as angular diameters. For our Sun and Moon, this is approximately 0.5 degrees. The Andromeda Galaxy, our closest galactic neighbour occupies a whopping 3 degrees of real estate in the sky despite being around 2.5 million light-years distant (the Moon is 1.3 light-seconds away and the Sun 8 light-minutes). It is far too large to fit into the field of view created by the specific camera/telescope I use which never fails to fill me with a sense of awe.

This image was shot just a few weeks back in freezing conditions from my Bortle 6 back garden in NW England and is presented in a HaRGB palette to show off the nebulous areas of star formation areas present within it.

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.
