The Whirlpool Galaxy & Friends

This has been an ongoing project that is still needing some final touches.

The data set is from

Luminance 34 x 900

Red 16 x 600

Green 16 x 600

Blue 18x 600

I still need to finish 16 x 1800 in Ha ; but I wanted to post this set as is uncropped to see all

that is going on in this image. What really surprised me is all the faint galaxy's and double stars

depicted edge to edge. The image is really teaming with life everywhere.

I also felt like posting this now since its my young 62nd Birthday today.

I decided to post a cropped version of the data that I currently have as is. This M51 image has been ressized somewhat to see additional detail from capture.

Various brush size filters were used in Photoshop throughout image and an HDR Multiscale of 3 was used in Pixinsight 1.8 to bring out the arms and core structure in better detail.

I attempted to avoid using as little noise reduction as possible so as not to loose detail in small background galaxies.

I used an autoscaled version for this image and attempted to control the background this way. The only problem doing it that way was the black point was clipped thus possibly loosing additional inner detail from the background.

I will re-process again once I have the Ha data available and attempt to blend this in with the red channel.

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.
