Images taken with Lunt LS60 or Lunt LS100 in single stack or double stack mode as indicated near the image. Using native focal length for full disk and 2/5x or 3x Barlow lens for prominence and surface detail.
Recording with ASI174. Typically 10% to 20% of 750 / 1000 / 2000 / 5000 frames stacked in AutoStakkert!3 wavelet sharpening in Registax 6 and finishing in Photoshop CS2.
Time-lapse videos with Python script and ffmpeg.

2023-02-19 19:44UT and 19:46UT. Some experimentation with low gamma setting during the exposure to bring out surface detail and prominences at the same time. Gradation curves were enhanced in processing.

2023-01-26 19:536T & 19:39UT The seeing contitions were not really good but for some active regions I was using the 2.5x Barlow lens for some good surface and prominence details.
