Much bigger than I thought...
As we were discussing in PMs a few months back.. You're always rewarded for going the long haul and capturing lots of data.. This image here is no exception.. 26hrs exposure is a monument effort that's paid its dividends by showing you just how far the helix goes... The question is this... How far do you think it would extend with 52 hours exposure and double the sub exposure length??
You know you want to find out mate..
