Solar Observing Campaign 2020

Latest observations added at the top.

Images taken with Lunt LS60 or Lunt LS100 in single stack or double stack mode as indicated near the image.
Recording with ASI174. Typically 10% to 20% of 750 / 1000 / 2000 frames stacked in AutoStakkert!3 wavelet sharpening in Registax 6 and finishing in Photoshop CS2.
Time-lapse videos with Python script and ffmpeg.

2020-08-08 19:05UT. There was a small sunspot and a prominence so it was time to get some images and later a time-lapse of the prominence. First the full disk image. This is a composite of two exposures individually for surface and prominence detail.

Here a detail of the sunspot and the prominence animation.

The Prominence was imaged with 2.5x barlow lens, Each indiv. image 10%/2000 frames at about once recording per minute. The total time covered is about 1hr from 18:56UT to 20:01UT

2020-07-06 19:32UT. There is still not much solar activity. Today the images were recorded to test the updated driver for the focuser and mount connection. Really not much to say about detail on the Sun.

2020-01-05 18:56UT to 20:24UT. The first observation for the 2020 campaign. We are clearly in the solar minimum. Not much activity at all. The Sun is low in the sky and the seeing is variable from average to very bad. I recorded about 90 AVI sequences of 2000 frames each. With 10% usage rate stacking was done in AutoSakkert!3 and sharpening in Registax 6. Some further processing with python scripts and Photoshop. Finally ffmpeg was used to make a time-lapse of the about 90min. span.
