02/07/2024 – More Time on a Couple of Planetary Nebulas

A nice cool and very clear Moonless night. I was able to capture a little more than 3 1/2 hours of light from the planetary nebulas PK 136+05 and PN G136.1+04.9. The planetary nebula PK 136+05, aka Hechathorn-Fesen-Gull 1 of HFG1, is the February 2024 Sky-Watcher USA Target of the Month (TOTM).

Telescope Control, Image Acquisition, and Image Processing Software
Equipment Control and Imaging Software: KStars/Ekos connecting to INDI Server on a Raspberry Pi
Stacking and Processing Software: Siril astronomical image processing tool

I was able to add another 43 x 300 second exposures to the 37 x 300 second exposures from 02/05/2024. A total of 80 x 300 second exposures or just over 6 1/2 hours of total time. All exposures were taken at 121 gain, 30 offset, and bin 2×2. The frames are calibrated and stacked using Sirilic and all processing was done in Siril.
