Reply To: Nova Cas 2021

Prompted by Jeremy’s post I thought it was about time to take another look at the nova and attempt a low resolution spectrum.
Well it just about worked but at mag 13 in a very crowded star field it’s not ideal for an objective prism. However it does show H alpha and H beta, the bright HeII line at 468nm and the close pair of lines at 529 and 541nm. The last spectrum in the BAA database, which shows the same features, was from December 2025…so I guess mine is better than nothing nine months on…?
The nova is directly below M52 and left of NGC7635 (Bubble nebula) forming a right angle triangle.
