Description

Temperatures were dropping fast last night with an eventual low of -11C and although the skies were poor, they were clear... so it was only right to get out there.

This is a 2 panel mosaic trying to squeeze in as much as possible within the Virgo galaxy cluster. I thought I had done a reasonable job until I saw the plate solved version here.. not even close! :)

The mosaic has a 20% overlap and contains 340 x 30s total subs - this ended up around 85 minutes per panel.

What a treat browsing over this 1:1 and finding the smallest smudge/line that you knew wasn't a star but another galaxy.

Captured with Voyager, calibrated & stacked in APP then processed in PixInsight.
