After a first session on X-mas day and a failed second session, a third session was completed on December 28.
This third session was a combination of H-alpha and Optolong L-Pro; all of them 300s exposure time.
Using APP, all images are stacked, resulting in a total integration time of 4hours 25minutes.
Bernard's Loop and Sh2-264, Lambda Orionis Ring or Angelfish Nebula is good visible. I'm still doubting on the quality of the images. Hopefully I can add one more session to get up to 6h total integration time.
