What does a Jellyfish, Monkey Head, and the number 35 have in common?

Jellyfish (SH2 248, IC443), Monkey Head (Sh2 247), IC444, & Sh2-249 emission nebulae, and M35, & NGC2158 star clusters. The Jellyfish, a 30,000 year old supernova remnant is about 5,000 light years away. I started this project just before Christmas and forgot it with the holidays and travel. A couple of clear February nights let me finish it in style. Four nights, with 
19 hours of #NBOSC exposures on 2025-12-19 > 2026-02-17 under Bortle 7 skies from Austin, Texas, rendered in an HOhO palette.

WO RedCat 250/51mm, L-Ultimate dual NB filter, ASI2600MC MC camera, ASIAIR Plus controller, AM5N mount. xx 5' exposures stacked and processed in PixInsight with RC-Astro and SetiAstro tools. Final exp and crop in Affinity Photo.
