Hello

Here is my first picture of deepsky with the edf155.

For this shoot, I choice the couple of m81-m82.

I use the stl11k with astrodon filter.

The exposure time is 3hr for the luminance and 40 min for each color

channel.

The picture is directely visible on my web site.

I recommand the full size image ;-)

Hello

Normally I make my picture from Brussels under light pollution. But, from one year ago I make a another choice :

I make the picture in h-alpha from Brussels, BUT, the RGB in Chimay.

Why : because the gradiant is more difficult to remove with lhe large chips of the ccd.

In Chimay the skies is better that Brussels. It's not perfect, but better.

The problem is the distance from my house (120KM far and 120km ago).

For this picture, I make the choice to go to Chimay, because it's only a lrgb picture, without h-alpha.

I'have some picture of the site of Chimay. I post it tomorrow, so you can see the medium condition of this site, when I try it m81-m82.

Why bad condition : the humidity and the high clouds is well visible on the picture of the site.
