Hi all,

I have the pleasure of presenting a new image framing the northern part
of the Great Andromeda Galaxy, M31.
The shots are the result of 2 nights split into 2 x 3 x 1800 seconds of
exposure
through the use of the telescope Takahashi BRC250 with ccd ST10 XME +
H-Alpha filter.

That's a lovely image; I particularly like the little blobs of H-alpha
emission that look rather like tropical thunderstorms do in satellite
pictures of Africa. Do you happen to know how big M42 or the Carina
nebula would look on that image scale?
