20091026 Sun

Very poor transparency today at 2/10, seeing 3/10. AR1029 can be seen in white light! Therefore, I pulled out my simple white light setup to have a shot first:

1525 (GMT+8), manual focus by looking into the view finder:-

1526 (GMT+8), autofocus by Live View contrast detection:-

My simple (lazy) white light setup consists of a Thousand Oaks Type 2+ Glass, Canon 450D with Canon 100-400mm at 400mm with Kenko 2x, handheld, spot metering.

And then I setup my H-alpha gear and it's definitely far more interesting. Again, taken with my Tele Vue Ranger with NGF-CM, Solarmax 40 with BF10, and DMK 31AF03. The full disc was taken with a reducer at the nosepiece of the BF10 and then the close up was taken with a Tele Vue 2x barlows:-

1547 (GMT+8):-

1548 (GMT+8):-

1553 (GMT+8), close up with 2x:-

Where did the name AR1026 come from? Thanks!

Sorry, this one should be AR1029 instead of 1026.

The National Oceanic and Atmospheric Administration (NOAA) will assign the number, basically consecutively.
