Nice. When did you manage to capture that?

 

Last night. Saw it wasn't going to rain so chanced it. Seeing was appalling going by the guide graph.

Excellent.

 

Sorry, can you tell me what HOO stands for ?

I'm assuming H-ydrogen alpha,  O-3.......whats the other 'O' ?

It's just the RGB palette assignation, so Red=Ha, Green=Red=Oiii. And thanks!

Thanks, and yes, 533MM-Pro. Paired with the MN190 it seems to be mega. Really happy, particularly with the new focuser.

Slight improvement now I've had a little more time. Limited by the data, I think...
