I'm guessing stacking 2 min subs at 800 ISO would provide good details as well and shouldn't look overexposed even with the moonlight.
would keep noise low as well. I'd say its worth a try to compare.
Did you find a reasonable amount of guide stars with the mini guider?
edit: my hunch is that with your dark skies and a the F4, the short sub will provide sufficient details at 400 or 800 since the object is bright.
Hi Alistair,
The only reason I went for 5 minute subs was to try out the auto guiding. I tried at ISO 400 but in moonlight it washed out at 5 minutes.

Cheers,

Justin.
