20100509 Sun

Seeing 2/10, transparency 5/10, cloud moving rapidly around, strong wind blowing occasionally.

Ranger with NGF-CM + reducer, Solarmax 40 with BF10, Meade LXD55 with a long offset plate, Lumenera LU070M with K3CCDTools.

1537 (GMT+8):-

I didn't do this kind of shots recently since the bigger dynamic range of the Lumenera can do it all at once, 1538 (GMT+8):-

Notice that the amount of detail in the first shot is more than the second one, since the shutter speed is faster and therefore, it freezes seeing better. So, I really have little reason to take a longer exposure shot for the prominences.
