Well done.... is there some violet fringing around the brightest stars?

[ZeroID (Brent)]

Violet or blue, yes. The scope is ED, not quite APO.

If you have photoshop cc, the camera raw filter will eliminate that fringing in seconds
I had a go here

Noel Carboni's astronomy actions for PS do it too. Otherwise nice shot Brent.

I thought it didn't matter if the scope was achro or apo with RGB? I'll have to try it sometime.
