Here are more data from the following day. Less images but they are better.
The IR image have been taken with the W47 stacked on the RG610 - a setting I like quite a lot because
the passband is much broader than that of the IR780, while still providing a sharp blocking of visible
red light, to thecontrary of my usual IR700 filter. The transmission may begin around 720 nm.
Images from sept. 4th will follow soon.
Best wishes
