Thanks. I will give that one a try when we have a decent night here. A calima has filled the sky with very fine dust 8-(
Would an off-axis stop help for bright objects, do you think? It would reduce the sensitivity and I generally dislike throwing away photons.
If I get anywhere I may consider using a more conventional spectrograph, but that is serious money to spend on a whim, hence the SA.
