NGC 1750 & NGC 1758

This image captures 2 open clusters located in the constellation of Taurus at a declination of +24 degrees. NGC 1750 is the larger cluster, in the bottom half of the image, at a distance of 2000 light years and an apparent diameter of 30 arc-minutes. Its true diameter is 17 light years. NGC 1758 is the smaller cluster, in the top half of the image, at a distance of 2500 light years and an apparent diameter of 10 arc-minutes. Its true diameter is less than half the size of NGC 1750, at 7 light years.

It is hard to discern this 2 clusters at first, not only from each other, but also from the background star field and the larger foreground stars. But with time and study, the clusters appear more distinct. I believe that most of the larger stars in this image, and particularly the orange ones, are foreground stars and are not part of the two clusters. The Astrobin mouseover shows the designations well. Also shown is the designation NGC 1746, which is thought to be an error and should be ignored.

Most believe that these two clusters are simply optically aligned and are not physically related.

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.
