Hi Clive,

Focal length's 3454mm, so a bit of a challenge for the guider.

Hi Alex,
At these focal lengths, with atmospherics and sky glow, they will be larger than normal.
The FWHM on focussing i got nothing under 5 during the session.
Even my secondary started fogging up with dew.

Heres one when conditions werent as bad, its the Bug nebular. Exposure is a single 2 minute frame.
