Big prominence warning!!!

[willis]

There is a very big prominence today! I did the observation in the recess, but I don't have time to take the picture today. Can anyone do it now??? Wish it can last longer!!!

Arh, I missed it. I was too lazy.

我明天"早"起，會把LS75F帶出去拍過痛快

現時我車上有DMK41、DMK31、DMK21，足夠選擇

快些有相片看就好了.

看來今天沒望了.....

昨晚太累，早一點回家，七時多已上床休息，晚一點起來沒有動力去拍些照片，再睡了

沒有動力去拍些照片

It is especially hard for me to go out to shoot the sun in the summer. So my solar pics are usually taken in the cooler months.

But may be an LS152T will give me some motivation.

[社長]

build a dome and you will find it easier to take solar image. Sir, you want one dome or two?

[David]

There is a very long filament on the sun today. I've just seen it with LS100T.

[社長]

you mean this one? just casually take it during lunch time...

image quality is below average due to thin cloud moving around.

Lunt LS75F unobstructed, APM-LOMO 80/600,
Televue 3x barlow, Imaging Source DMK31 camera
Effective focal length 1800mm
Gain 600, Exposure 1/38s, 30fps, Gama 80
Photoshop CS5 crop, curve stretching, resizing

seems 1800mm is a bit too long for LS75, so a 2.5x or 2x barlow is better for my case.
