The most prominent object in this Cassiopeia Milky Way star field is the open cluster NGC 225 and the associated reflection nebula VdB 4. NGC 225 was discovered by Caroline Herschel on September 27, 1783. NGC 225 is 2100 light years distant and its visual magnitude is 7.0. Also seen in this field is the open cluster NGC 189 (bottom center) which was also discovered by Caroline Herschel on September 27, 1783. NGC 189 is believed to be 3500 light years away and its visual magnitude is 8.8. The third open cluster in this field is Berkeley 3 (upper center), which is also known as Stock 24. Finally, several members of Beverly Lynds’ catalog of dark nebula can be seen in the field – LDN 1302 and 1291 are on either side of VdB 4. LDN 1300 is directly below NGC 225 and LDN 1298 and 1290 are toward the bottom of the frame and to the left of NGC 189.

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.
