Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "M51: The Whirlpool Galaxy." Lying some 31 million light years away in the constellation Canes Venaciti, M51 provides a full face-on view of what astronomers call a "grand design spiral galaxy." Also known as NGC 5194, M51 has been demonstrated through radio observations to be interacting with its smaller partner, NGC5195. Therefore, the two are often shown together as we see in this photo.
I can't blame you if you think this is a Hubble shot...but it isn't. It is a composite of three images captured over a total exposure time of 34 hours from a 24-inch telescope located in New Mexico. Here are the other technical stats from the astrophotographer's web site:
Dates acquired: March-April 2020
Camera: FLI PL16803 (4096x4096 pixels)
Guiding: Astrodon Monster MOAG off-axis guider
Filters: L (light pollution), Hα, and RGB
Processing: CCDStack and Photoshop 2020

Good Thursday Afternoon Maj William W. 'Bill' Price and what a beautiful Galaxy this M51 is! The colors collected from the composite images are amazingly beautiful... One of the best captures I have seen in a long time... I found this to be a fascinating APOD and as such, I did find a wonderful short video of this galaxy with excellent text descriptions as well as beautiful background music... This is an excellent adjunct to an already wonderful APOD. I believe all of your APOD followers will enjoy this...

Maj William W. 'Bill' Price good day my friend, what a interesting read and share. I have said UT many times before, and I will say it again, " nobody does it better from above". Thanks for the Today's Astronomy Picture of the Day M51. HAVE A BLESSED DAY!
