Here is my spectrum from last night using the ALPY 600. (The red line is filtered to R~300)
This is the faintest target I have attempted with the ALPY600 setup and the SNR is very low. The broad H alpha line is obvious though and other Balmer lines are present too. I have also marked the Fe II curtain lines though they are only marginally detected above the noise.

Cheers

Robin
