M97 Owl Nebula & M108 Surfboard Galaxy in HOO

M97 Owl Nebula & M108 Surfboard Galaxy 
 This 3 nights of imaging was a test for my mount which was sent off to ZWO to repair the USB-C port in the mount saddle. The mount worked fine with the USB-B port in the mount body, but I prefer the saddle port because it elimiantes any chance of a cable snag. Even with a fairly bright moon out, I was pleased to get a clear view of the central star in M97 and M108 looks good in this narrowband image. 16.2 hours of #NBOSC exposures on 2026-02-05>07 under Bortle 7 skies with a gibbous moon from my garden in Austin, Texas, rendered in a HOO palate.

WO RedCat 250/51mm, L-Ultimate dual NB filter, 194 5' exposures 2x drizzle stacked and processed in PixInsight with RC-Astro and SetiAstro tools. Final exp and crop in Affinity Photo

The central star is clearly visible at full resolution. It has shed its outer layers into a planetary nebula and is condensing to for a white dwarf star.
