So, here's other technical questions.
Should the spectra be always horizontal to the camera chip?
As, the comet is moving at usually an angle to stars, should the SA100 be rotated to make the spectra align at 90 degrees to movement angle?
or, perhaps aligned so that it appears ahead of the moving object?
I definitely need longer , exposure seconds, but will that make spectra banding more visible? I am expecting that only broader features are achievable.
Kind regards, Alan
