During processing, I observed an interesting feature next to the IC 443 nebula: a distinct, yet seemingly uncatalogued, reflection nebula being lit by the bright star 12-Gem (HD 43836). To properly showcase this subtle blue detail, I chose to blend the full RGB capture with the HOO narrowband data, rather than using the RGB solely for star replacement.
