m106 HaLRGB

An active galaxy, as evidenced in the strong Ha signal near its galaxy core, m106 is a Seyfert galaxy with a very bright core and seems to cover the EM spectrum with massive radio radiation and a microwave 22 GHz water maser from the purple outer dense clouds. It is 22-25 lyr distant in Canes Venatici. It is similar in size and luminosity to the Andromeda Galaxy, but has a supermassive black hole at its center.

This is a 14.9 hr HaLRGB image which is a revisit to a previous 13.5 hr composite LRGB version from April 2019. The new HaLRGB version now adds 1.33 hrs of Ha collected recently on 5/24/2020 with my current FLI ML16200 camera. The new Ha shows some of the wisps of gas being pulled into the central black hole. "At its heart, as in most spiral galaxies, [M106] is a supermassive black hole, but this one is particularly active. Unlike the black hole at the center of the Milky Way, which pulls in wisps of gas only occasionally, Messier 106’s black hole is actively gobbling up material. As the gas spirals towards the black hole, it heats up and emits powerful radiation" [Wikipedia].

The older data used in the image is 6.2 hrs of RGB data from 2014, collected with an FLI ML8300 camera, and 7.1 hrs of RGB from 2012, collected with an SBIG ST-2000M. The scope in all cases was an APM LZOS 130/780 f/6 LW CNC II 130mm APO on a Takahashi EM-200 Temma2 mount. All data were taken from D.A.R.C. Observatory, Mercey Hot Springs, CA. North is to the right.

Satellite galaxies NGC4248 and NGC4258 are also visible in this image.

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.
