This is a nice presentation of the nebula Andrew. Like the subdued colours a lot.
Well done.

As for resizing: if you have software that gives you options, then BiCubic for shrinking.
This is a good site for info on photography basics from Cambridge Uni, and this page relates to resizing images downwards.
If you go to the main menu, there is one on upsizing too.
