excellent spectrum Terry. I attempted it a couple of nights earlier, but managed only a single 1200s exposure as guiding was failing to keep it on the slit, and it took me most of the evening to find the object on the finder chart. The exposure has the barest ghost of a spectrum showing nothing after reduction.

I will attempt at2021wui again when conditions allow, as I think it deserves further investigation.

My spectrum from last night - 11 September 2021.

Balmer lines remain redshifted but less so than last week. Its another noisy spectrum - just over an hour's integration time - so its hard to pick up much other than HeI at 5875 and 6678.
