Details:
Today is my first success to simultaneously image the Sun (1:08 PM UTC+2) on a single a bit old but still powerfull computer (Win10).
Presented here are the results of 2 simultaneous Firecapture session.
One session shows the whole disc (Saturn-M SQR camera at 6 FPS at the main focus of a 102/900 Fluorite
PV refractor using 90 mm Coronado filter + BF30)... The black rectangle shows the FOV of the second session).
The other session shows details of the (3301 3302 3305) sunspot group (ASI174 MM, Quark chromosphere on a 160/900 Cosmos achromatic refractor at 60 FPS).
As you can see no special artifacts.
