Mask with Clean background (no signal??)

My 5th attempts at e-corona. Failed to get any signals previously. My guess was poor seeing condition. Today (2May26), working on 30 only recordings, I can see some faint signs of the corona at about 2 o'clock position. Settings: Gain was set to lowest 100 and Exposure 5ms. Forced polynomial detected Fe1. Masked Images range from clear to noisy background reflecting the seeing conditions. Unfortunately I only managed to record 30 SER files before the clouds came. I would appreciate it if you can let me know if I am on the right path. I hope to record at least 200 SER files when the sky cooperate.
