Bought a D5300 last weekend to supplement the D7000 I've been using for a few years.
Figured without the OLPF and slightly better noise performance, and being lighter, it would be a good fit.
Turns out I was right
Didn't nail my tracking and the LP was a factor, so I limited subs to 30secs at ISO4000.
Obviously its a bit noisy, but I'm pretty happy with it.
Darks and flats applied
