Hi Matt,
The barlow (Meade S5000 2x telextender) is before the flip mirror, so the backfocus position should be the same, I did tweak the focus between colour and mono, but I'll setup the helical focuser on the flip mirror properly next time so I don't have to. This should result in exactly the same image scale as the two CCD's have the same pixel size.
Cheers
Stuart
