Well Alex, a big hearty congratulations on your first light success
(that's a dang, dang). We all have a first ever astrophoto (arhem...
here is mine
) and now you have yours
(which is much better than mine)
It's great to see another passionate participant enter this exciting, rewarding and, yep, even privileged pastime. Exciting because you never know quite what you might reveal, rewarding because it takes a bit of thought, preparation and processing, making the results personal and satisfying and privileged because, well, in the scheme of things, very few of us humans actually get to be able to capture/reveal/showcase the surprisingly spectacular wonders of our otherwise, seemingly mundane night skies...
What you really need, is a dark sky, oh, at say
..maybe just under 1500m up..? under a dark pristine clear mountain sky somewhere (or know someone who has this
)
and an experienced mate, who can give you some pointers along the journey....I'll see if I know anyone..
...and get back to you
Welcome to astrophotography
Mike.
