Description

NGC 253 Sculptor Galaxy

I picked up a very cheap Sony Nex-5n on ebay and tried a Do It Yourself Full Spectrum Mod, it seems to work well, the Nex-5n is a 16mp and has IR remote shutter, much better than the Nex-3 I was using with no remote shutter.

The 5 x 3min unguided subs worked well so I added 3 x 5 min subs and also pushed the limit of unguided subs for my setup with a single 10 min sub which gave nice detail but caused bloated stars, I think for unguided I need to stay below 5 mins.

5 x 3 min subs at iso 1600 (unguided)

3 x 5 min subs at iso 1600 (unguided)

1 x 10 min sub at iso 800 (unguided)
