M106/NGC 4258

Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert. Seyfert galaxies are one of the two largest groups of active galaxies, along with quasars. It is one of the largest and brightest nearby galaxies, similar in size and luminosity to the Andromeda Galaxy.

A bit about the image now. I took this image using a remote telecope provided by iTelescope located in New Mexico. I have used used both LRGB and narrowbanf filters for this image. I guess most experts will question my use of the narroband filters for a galaxy image. Normally I wouldn't have done that either. I tried to see whether I could capture those wonderful red filaments that can be seen on the Hubble image of M106. As you can see, that did not work :-). Also, because of the relatively short exposure the quality is not great either.

Also visible in the mage are NGC 4248, NGC 4231, NGC 4232 galaxies. NGC 4231 and NGC 4232 are paired together.

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.
