Just regurgitating what ChatGPT suggests for hot pixel ... it involves darks. When you use this capability on the Seestar, you can hear the "dark" filter get engaged. If this isn't taking a dark frame, my apologies. I've misunderstood the process. I guess where this does deviate is the "same exposure time" when using the ZWO app. Other third party apps connected to the Seestar (via Alpaca) allow for Dark Frame engagement for a user defined exposure time.
From ChatGPT (which could be incorrect):
What Causes Hot Pixels?
Long exposures (30s, 2min, 5min+)
High ISO settings
Warm sensor temperature
Older or heavily used camera sensors
They’re different from:
Dead pixels (always black)
Stuck pixels (always one color)
Amp glow (sensor-edge glow)
🛠 1. Best Method: Dark Frame Subtraction (Most Effective)
This is the gold standard for astrophotography.
📸 How It Works
You take a photo with:
Same exposure time
Same ISO
Same temperature
Lens cap on
This captures only sensor noise (including hot pixels).
Then software subtracts that from your light frames.
