Messier 42. The Orion Nebula. Low exposure image to display the "Trapezium" star cluster.

Most images of M42 are tailored to capturing the nebulosity in this famous object. The Trapezium sits at the core of this star forming region and this image was made with short exposures so that it is displayed prominently.

The Trapezium is probably at its best when viewed directly through the eyepiece of a telescope.

The telescope used here is a Celestron C5 Schmidt-Cassegrain. It gives nice views and images of nebulae although the central obstruction has a softening effect on images so that the stars are less sharp.

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.
