Andromeda galaxy is the closed galaxy of our home – Milky Way galaxy. The diameter of Andromeda is approximately 220,000 light years; which is twice more than has Milky Way. It’s only 2.5 million lights away and it’s getting closer. The collision with the Milky Way is predicted to happen in approximately 4 billion years.
This DSO is one of the brightest and the biggest, which makes it relatively easy to photograph. This is actually my second attempt of Andromeda galaxy. One year ago with DSLR camera the picture was not looking so great, therefore I was waiting a year and here is the result:

Nice photo from our neighbour galaxy !
I think the planned mix from SW-/HW- experiences+recommendations and photos is a good start for such a blog.
Enjoy your blogging.
