M108

Messier 108 (also known as NGC3556) is a barred spiral galaxy in the constellation Ursa Major. It was discovered by Pierre Méchain February 19th in 1781 or 1782. From the perspective of the Earth, this galaxy is seen almost edge-on. Distance is 45 million light years away. This galaxy is an isolated member of the Ursa Major Cluster of galaxies in the Virgo super cluster. It has a morphological classification of type SBbc in the de Vaucouleurs system, which means it is a barred spiral galaxy with somewhat loosely wound arms. The maximum angular size of the galaxy in the optical band is 11′.1 × 4′.6, and it is inclined 75° to the line of sight. This galaxy has an estimated mass of 125 billion times the mass of the Sun and includes about 290 ± 80 globular clusters.

Observation Notes : M 108 Bright, large, very much elongated in PA 80 at 100X. Even at 200X, this is the most stellar nucleus I remember seeing.

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.
