******************* Episode 12 reminder
Sometime between Wednesday 5/17 at 4:23 am Pacific Daylight Time (PDT) (5/17 11:23 am UTC) and Thursday 5/18 8:58 pm PDT (5/19 3:58 am UTC) one of the stars (21 million lightyears away) in the Pinwheel Galaxy went Supernova.  It exploded with so much energy that we can view that individual explosion on earth.  Since I was imaging continuously with 10 minute exposures, I created a time lapse starting Tuesday and completing on Sunday.

********************End Reminder
Episode 13, I was imaging the Pinwheel Galaxy for 6 nights (Tues May 16 - Sunday May 21) 6 nights at San Diego County Agua Caliente Hot Springs campground and I captured 2023ixf Supernova while it was happening in real time (although it did take the light 21 million years to get here).  Agua Caliente Hot Springs is a Bortle 2-3, full hookup campsite in the desert within the Julian limits.  In this Episode I calibrated and registered the images together with a blinking Hydrogen Alpha (Ha) overlay.  These 2 images were created out of the 196 - 10 minute frames that I collected from 5/16/2023 - 5/21/2023. The first image is Luminance, Red, Green,  Blue (LRGB) and the second is LRGB with Hydrogen Alpha (Ha).  As you  see them blink back and forth, notice the Ha (red) regions).  These are the hydrogen rich Nebula regions within the Pinwheel galaxy where star formation is very active.  What I can conclude is the 2023ixf Supernova is in part of the galaxy where there is little to no Ha, meaning little to no star formation and most likely older stars in that location.  So the Supernova occurred in an older part of the Pinwheel galaxy, where star formation used up most of the Ha and most of the star formation was concluded millennium ago.  This makes intuitive sense since a star goes Supernova at the end of its life when it has burned up most of its primary fuel (Hydrogen).  I highlighted the Supernova in the LRGB image in yellow (it is in both images, but I highlighted only one).  The Supernova is extremely hot and blue in color.  

I captured this astronomical data using wide band (visible light) Lum, Red, Green, Blue and Narrow Band Hydrogen Alpha (Ha) 3 nanometer filter over 6 nights, 5/16/2023, 5/17/2023, 5/18/2023, 5/19/2023, 5/20/2023 and 5/21/2023 from Agua Caliente Springs Campground (Bortle 2-3 light pollution rating).
