Triangle Galaxy (Messier 33)

"Los Cielos de Chile"
Image taken from Chile with a
Takahashi TOA150 refractor (150mm diam at f/7.3), an astelco NTM500
mount and a SBIG ST11000M CCD camera + astrodon RGB filters. Exposure
times are 2 hours in R, G and B. From North of Chile M33 does not go
much higher than 30 degrees above the
horizon which makes the photography difficult and very sensitive to
turbulence. Hopefully the sky quality in the Atacama desert is also
often very
good . You will find below a binned version of the full
field but you should also have a look at the unbinned
crop of the galaxy itself further down this page.
