Hi,
Below is sunspots picture taken in the afternoon. By using B/W mod ToUcam. The mod webcam really give more details and contrast. I was suprise on the first image been processed. It much better than what I can get previously.
I still don't know why the image taken with 8" SCT looks not solid and like been shaken...? Is that because of therma unstable inside the tube? Or seeing?
