[QUOTE="aroy, post: 290064, member: 16090"] Shoot with fast primes. They will require less exposure time and have less distortion. In general longer lenses give better results, so instead of using 8-16 zoom, try using a 50mm F1.8 prime. The D version sells under US $100, so it is not a bad investment. Shoot in RAW with all the corrections switched off - D light, NR, Distortion etc. All these can be done while processing RAW. Remember that D7100 RAW will have a DR of 13+EV, while jpeg has 8 or less. Shoot RAW and then use post to extract information in the deep shadows (so to speak). One trick used by astro photographers is to do; a 50 to 200 shots of 1 sec or less; time lapse and then merge the shots.
