>>2905942Generally any DSLR with cmos sensor is okay for beginning - I shot this one with $40 canon 350d and kit lens. Sure, it's not some kind of glorious sharp professional astro shot, but keep in mind that it was my first week with DSLR in my life.
So, D5300 will be absolutely fucking amazing. I doubt you can do any better, modern Nikons are probably best crop sensors in terms of low-light performance.
>screen rotatesyou won't use your live view in the middle of the night for anything other than focusing (and even that is sometimes easier to be done in viewfinder), so don't get so attatched to all of those modern gimmicks. Of course it's good to have those, just don't consider it as absolute requirement.
