About this image

Switched from the 3 degree to the 9 degree objective prism to boost the resolution of the spectrum. Much better result than a few days ago showing hydrogen emission lines. But still not much else...

Field ~62 x 57 arc minutes with north up closely matching the field of the AAVSO chart. Nova has H alpha and beta emission lines identified.
