Occultation Beteigeuze 12.12.2023
Very simple Observation - Even the
Video-Funktion of common DSLR are
OK
But better is a more sencitive camera like the Sony 7s.
This cam delivers enough senitivity for some experiments.
An other Idea to work in the Light of
UV - Maybe it´s possible
that we see here a total eclipse. Suitable are Venus-Filters:
Unfirtunately common foto-lenses
don´t work in UV. So
I´ve testet a Mini-Dobson on a mount together with a
B&W-webcam.
Also an idea ist to combine a camera with
a spectral-trick filter:
Here a 14mm foto-lense together with an adaptor and some scotsch-tape
This allows to measure the light curve in different lines in the same
time!
Old damaged Optics can be an advantage! - because they blur the star
and an overexposure is no problem.
If you have only good new digital optics...take a pot of creame:
