About this image

I collimated the scope this eve before taking the latest spectrum. The seeing was OK and I was pleased with how sharp the spectrum of WZ Cas looked.

You can easily see the absorption troughs attributable to C2 and CN as well as the metal lines Na I at 5889/96 A and Li I at 6708 A.

* This is uncorrected for instrument response, and the units on the y axis are arbitrary.
