I'm 1200ly out in my cobra and I have amax 15.4ly range on the FSD that I have. As long as you have the Advanced Discovery Scanner and the Detailed Surface Scanner You can head out and find some great looking planets as well as interesting systems. Of course not every night is great. Earlier in the week I spent two night looking at ice plantes and the odd gas giant. Then on Thusrday I found three water worlds and two gas giants with water base life. Last night was not too bad I found one Amonia base world with life.
