Woohoo! Daylight saving is gone... clear sky and in the obs tonight!
This is the first spectrum (half) processed with my SA in my new filter wheel.
Shot this spectrum of Eta Carinae so I can measure the dispersion of the new setup - 8.98 A/pixel with the camera directly behind the filter wheel.
It means maybe a bit more processing with the DMK21 since it's nearly always 2 frames to join to get the full spectrum, but that's OK at least for now. Maybe a DMK41 might appear on the scene
.
Seeing was pretty ordinary.
I shot some more spectra of Sirius, betelgeuse, Hadar, Alpha Cen, Gamma Crucis, etc yet to be processed.
