Hi there. I just bought myself a OMD EM-10 with Olympus 17mm 1.8 and 45mm 1.8. I live in a really light-intensive major city, so I have no easy fast way of trying and failing in astrophotography (I did not know this was possible, but thanks to this forum, I now know it`s possible, just not how it`s possible). In about a month, I`m going for a vacation in a low-light countryside next to a abandoned castle, and I think it would be really great to try to take some astro-pictures of that environment with one of my lenses or both. So, I need some help. Is there a walkthrough out there that I can read to get a quick explanation? And do I need to buy anything else ? (One guy here used a filter that I`ve never seen before). Btw, I`ve got "Creative Cloud" package with Lightroom and Photoshop. I`m sorry if this is posted in the wrong forums, if it is, can some kind Admin move it? Thanks in advance.
