M106 LRGB (Ben Koltenbah)

M106 LRGB

This is an LRGB image of M106 in Canes Venatici. Referring to Jeff Kanipe and Dennis Webb, Annals of the Deep Sky, vol. 3, M106 is classified as a "barred LINER spiral with a Seyfert 2 nucleus." It has magnitude 8.4, size 18.6' x 7.2'. It has a prominent nucleus with double S-shaped spiral arms extending N and S from the center. Surrounding this is a fainter region showing wispy star-forming knots that can be seen in my image.

One of the prominent features of this galaxy that has been deduced is a super massive black hole. The central object has "a mass of 36 million suns packed within a volume less than 0.8 of a light year ... in diameter." This is a region of size 51,000 AU's.

Its distance is measured to be 7.2 Mpc or 23.5 Mly.

To the upper right is companion galaxy NGC 4248, visual magnitude 12.5. Although a bit small in my image, one can see its irregular elongated shape with bright central ridge.

My C11 Edge system on the AP Mach1 mount continues to exhibit a prominent underdamped vibration, which can be seen in the stars as vertical elongation. I hope to have this and some other issues resolved soon. As a consequence of these issues, I needed to darken the background more than I would have wished, and I also felt compelled to take additional processing steps in deconvolution and sharpening that I would prefer to forgo in the future once the issues have been resolved. I also pushed the noise reduction, particularly in the color channels, a bit more than I had intended. If I return to process the data again I will dial these steps back a bit.

Description: Updated LRGB Image: I was encouraged to process my data again and work on evening out the background. There are some issues I'm hoping to resolve soon that are complicating calibration. This results in the need to make more herculean efforts to smooth out artifacts in the background.

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.
