It is hardly news to those who read uk.sci.astronomy, but this morning
the sky is unusually clear and blue, so I went out just before sunrise
and marked a position where Venus was lined up with a chimney, then
looked again 40 minutes later. Venus is easy to see in a clear blue
sky as long as you know approximately where to look. Clearly visible
and bright, at 0740, well after sunrise this morning 5 October. Just
looked again at 0750, still there despite having the Sun shining
directly on me.
Earlier, I went out and saw an impressive line-up of planets and
waning crescent Moon, with bright and very orange Mars high up near
Castor and Pollux, brilliant Venus, and fainter Saturn. Predictions
suggest we are in for a few clear days and nights, so grab 'em.

I was looking for Andromeda (the galaxy) last night through 10x50
binoculars.
I could definitely see it but it was very faint, would I need to use a
telescope to discern the disk structure or just dark skies?
You would need to take a long exposure (3-4 mins) with a CCD using a
telescope of at least 6-inches aperture. You would need to have a
larger format CCD to take in enough galaxy to see the spiral arms, or a
focal reducer, or both.

OK, thanks for the tips.
Looks like it was pretty futile trying to see the disk with the
binoculars then!
You would be able to see the inner region around the nucleus as a fuzzy
elongated blob, brighter at the centre and fading out. Features further
out would be too faint to see this way. With binoculars I doubt that you
could see the dust lanes or spiral arms, which is what I took you to mean
by "seeing the disk". (Maybe you could just manage to do this with very
large binoculars in a very dark site.)

It was resolvable as a fuzzy blob, but not really elongated in any
direction. It was at my semi-urban location though so next clear night I'm
going to drive out to the peaks where its much darker and see if I can see
any more.
Must admit I'm far more interested in objects I can see directly through the
binoculars or my 6" reflector than any CCD stuff. That is no doubt
fascinating but a whole hobby in itself!
