20101218 Sun

The sky is still very clear, a little bit less transparent than yesterday but it's close. Seeing is better, however. I would rate seeing at 4/10, transparency at 7-8/10.

There's some nice prominences around. I've tried to do a big mosaic which is the first time with my Lumenera. Clear sky is a must for good mosaic or else cloud will be a huge hindrance. Good solar activity is helpful so that you have alignment point for registax in each individual frames. I found that the high frame rate of my LU070M is very useful, since it shortens the time required for each individual shot!

The mosaic is not posted due to the limitation of inline image of blogger.
