Hi Peter,
wow - it's nice when a new system all comes together like that -
that's a top picture -
a high efficiency mono camera - IMX571 chip - up to 90% QE -
and the Barlow is doing well too at 2X mag.
1.7 FWHM is great seeing - I take it you're at a dark site at Rylstone?
I hope you can get some colour subs too.
cheers
Allan
