This is just the Takahashi TOA 130/ASI2400mc data for full field of the 'southern' North America frames I shot the night of August 11.
This data was collected during a session from two telescopes mounted side-by-side on a CGE Pro: a Takahashi TOA 130 with 645 field flattener (f7.7) with an ASI2400mc-pro and Optolong L-Ultimate 3nm Ha/Oiii filter, and an Askar FRA600 with the 0.7x reducer (f3.85) with an SBIG 8300m and an 8nm Sii filter. Ambient temperatures started at 30 degrees Celsius, so for the first hour the cameras were set to -5 before being dropped to -10. I only used the Takahashi data for the HOO result.
Capture details:
Takahashi/ASI2400mc - 64x300s (5h20m) [L-ultimate Ha/Oiii]
Location: Cobble Hill, British Columbia (August 11, 2025)

For processing, I calibrated the Takahashi data set with temp-matched calibration frames. I then split the debayered data from the ASI2400mc into R, G and B stacks to separate the Ha and Oiii. The B and G channels were combined to produce the master Oiii frame.

I then used a basic HOO blend approach of R=Ha G=[(0.7*Oiii)+(0.3*Ha) B=Oiii
