Dragonfly 44 (UDG) captured with amateur equipment

This is the famous galaxy almost made entirely with dark matter.

I believe this is the first time (?) this object has been captured by an amateur astronomer with amateur equipment.

"Dragonfly 44 is an ultra diffuse galaxy in the Coma Cluster,Observations of the velocity dispersion suggest a mass of about one trillion solar masses, about the same as the mass of the Milky Way.

This ultra diffuse galaxy (UDG) is discovered by the Dragonfly telescope array team.

the galaxy emits only 1% of the light emitted by the Milky Way. The galaxy was discovered with the Dragonfly Telephoto Array

In August 2016, astronomers reported that this galaxy might be made almost entirely of dark matter"

I captured this object in the Coma wide field about 5 nights of imaging with total around 18 hr of imaging time with LRGB. This was an accidental discovery from my image because originally I was plan to capture Coma galaxy deep field. While reading on Dragonfly 44 I noticed it is located in Coma cluster so I went head and found it in my data.I was extremely pleased with my result and happy that I have captured something this rare and unique object.

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.
