M-102 (NGC-5866) Lenticular Galaxy in Draco (Close up)

M-102 is a 10.7 magnitude lenticular galaxy in Draco. It features an extensive halo and an equatorial dust lane. This object has been a source of conjecture for many years as to its status as the 102nd entry in the Messier catalog. Both Messier and Pierre Mechain recorded this object, with Messier including it as number 102 in his catalog of 1781. Later, he indicated that it might have been a duplicate observation of M-101, but with the wrong coordinates entered. Subsequent research by several observers (Smyth, Shapley, Davis and Hogg) have suggested that the confusion was due to several clerical errors, including a 1 hour difference in RA between the M-101 and M-102 observations, as well as mis-identifying Theta Bootis as OMICRON Bootis. Brecause of both Mechain's and Messier's descriptions, NGC-5866 is a better candidate to be M-102, as M-101 is too large and extensive to have been mistaken for a smaller lenticular galaxy.

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.
