Description

An active galaxy, m106 is a Seyfert galaxy with a very bright core and seems to cover the spectrum with massive radio radiation and a microwave 22 GHz water maser from the outer dense clouds. This was originally a 13.5h LRGB image with (7.3h Lum, 6.2h RGB) which is a close-up crop and tweaking of a composite image using data from 5/15/12 & 5/19/12 (7.1 hrs) and 4/29/14 & 5/25/14 (6.2 hrs). All data taken from D.A.R.C. Observatory, Mercey Hot Springs , CA.

However, Rev D is a 14.9 hr HaLRGB image which is a revisit to the previous 13.5 hr composite LRGB version from April 2019. The new HaLRGB version now adds 1.33 hrs of Ha collected more 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] has 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].  Satellite galaxies NGC4248 and NGC4258 are also visible in this image.

The older data used in the image (6.2 hrs of LRGB data from 2014) was collected with an FLI ML8300 camera, and, before that, 7.1 hrs of RGB from 2012 was collected with my previous SBIG ST-2000M camera. The scope in all three data years using different cameras and filters was an APM LZOS 130/780 f/6 LW CNC II 130mm APO on a Takahashi EM-200 Temma2 mount.
