Description:
But what if it's windy? I ran a test last night on a breezy night to see if I could add details to my filenames that would help me sort out wind-blurred frames from relatively calm frames. In NINA I changed the saved filenames to include certain details to help me with this. Here is the format I used: Target Name_Date_Time_Gain_Exposure_Eccentricity_Star Count_HFR_Sub Number (NGC 281_2023-11-28_18-10-10_250_3.00_0.38_162_1.99_0002) The main details I monitored were Star Count and HFR. I found any HFR over 2.25 was too blurry to use. Also any Star Count under 50 was also too blurry to use. Using this method of sorting I captured 1500x3 second subs and 409 survived my sorting, giving me a total of 20 minutes total intergration time. The result was a decent image of NGC 281, The Pacman Nebula, taken on a moonlit, breezy night in Bortle 7.
