All good things must come to an end (George Harrison)! Messier 61 is the last of the great galaxies in the Big Dipper and Virgo regions I have been imaging since February. Although it has been fun, I am ready to move to something different such as nebulae and clusters. Unfortunately the next set of Messier Objects are not visible from the Happy Frog Observatory located in my yard so I will have to drive to my alternate location.

M61 (or NGC 4303) is one of the largest barred spiral galaxies in Virgo and approximately 52 million light-years from Earth. It has a diameter of about 100,000 light years which is roughly the same size as our galaxy, the Milky Way (source: Messier Objects).

Only 22 Messier objects are left on my catalog but it may take a while to image them as only about four are visible from my yard.

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.
