20 minute subs are fine but this is RGB? It may well be the cause of the uber reflection? Whats it like with shorter subs, say 10 minutes?

Good shot, mind. Like it a lot
Thanks David.

Interesting. I tried reducing the exposure times with Alnitak once, and still got the same degree of annoying reflection. Also tried removing the light pollution filter (on the telescope end of the imaging train - so thought it might be the cause), to no avail

There's also an observation on Astrobin that the angle of reflection shows I'm a bit out of collimation. Seems a fair point - I need to check!
