20081115 Sun

Seeing 5/10, transparency 5/10.

Telescope: Borg 45ED II
Filter: Solarmax 40 with BF10
Camera: DMK 31AF03.AS
Mount: Meade LXD55

I tried to do one set without tuning T-max, and the field is more "homogeneous".

1321 (GMT+8):-

1322 (GMT+8):-

And then I tried to do another one set after tuning T-max (my usual practice):-

1323 (GMT+8):-

1324 (GMT+8):-

Finally, another closeup made with a Tele Vue 3x barlows.

1327 (GMT+8), actually, I wanted to use a 2x, but my hand touched the 3x first and so... being lazy, I used the 3x:-


Tele Vue 3x barlows with a 16mm Tele Vue Nagler Type 6. The solar disc can just fit into the view, with nearly no black sky surrounding the red disc. Prominence can be seen even at the very edge of such a wide field. Very nice indeed.
