IsWe 2 (Ishida Weinberger 2, PN G107.7+07.8, PK 107+07 1 and others) is a faint planetary nebula located approximately 850 light-years away in Cepheus. This might be the faintest object I’ve imaged. Placed well in the sky, I was able to point at it over many nights when the moon was an issue.

Ha – 102x1800s – 3060 minutes – binned 1x1
RGB – 8:8:7x300s – 40:40:35 minutes each – binned 2x2

3175 minutes total exposure – 52 hours 45 minutes

Imaged over nineteen nights from Dardenne Prairie, Missouri (a red zone) and the Danville Conservation Area (New Florence, Missouri) from October, 2019 to August, 2021 with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.


Seven hours of OIII exposures didn’t pick up any nebulous data.
