Hi Chris !

 

I dont have the impression that the 400 that I used is grainy like your shot ?!? but I'll have to shoot the MWay and see.

 

What's telling you that is not sensitive in blue ? the stars or the nebula ? on your picture , we can see the blue on M20 ;)

 

at least , the nebula are red ;)

 

I'll look forward to your next phases.

 

Thanks to going trough these test !
