Description

G'day,

This is a 6 panel mosaic of m17 shot with an RC8.

The oiii, ha and rgb star colour data was from a previous image taken with a completely different setup. I quite like the colours but was never happy with the resolution so I decided to spend some time re shooting the ha with a longer focal length.

6 panels x 45 subs @ 600sec

As always any CCs are appreciated.

Cheers George
