This RGB data was taken remotely from Dark Sky New Mexico with a 106mm f/5 Takahashi refractor and an ASI2600 camera. Two nights were used to collect 7 hours of exposure: 10/20/2022 and 10/24/2022.


Exposure Count Binning
Red 140 min 28 x 5 min 1x1
Green 140 min 28 x 5 min 1x1
Blue 140 min 28 x 5 min 1x1
