Hi Darrell- One of the big problems to finding Venus in the daytime sky
naked eye is that your eyes normally focus at 12 to 15 feet if you are not
reading a book or newspaper or looking at a distant mountain. Getting your
eyes to focus at infinity is a real trick and having the moon handy to get
to the infinity focus did the trick for you. Up in Alpine finding Venus in
the daytime is easy and when your eyes snap into infinity focus it is
amazing how prominent it is in the dark blue sky. As your eyes are
approaching infinity focus I am always overwhelmed by the amount of
particles, spider webs, etc you see floating over you. These are a real
distraction, but once you focus past them Venus snaps out at you in full
glory. I followed Jupiter once into early daylight, but nothing compares to
Venus blazing away in bright sunlight. The same thing applies with an
optical telescope. If you do not have it focused at infinity you can be
looking directly at Venus, but will not see it due to it being way out of
focus.
Regards
Keith Parizek

I was able to spot Venus during the day on Dec 1 at around 3:30PM - when
it was conveniently near the moon. I'm pretty sure that I wouldn't have
found it using only coordinates.
And I only "sort of" cheated. After being unable to pick it out by
naked eye, I resorted to binoculars to find it, and then was able to
pick it up by eye.
A first for me and very cool.
Holiday best,
Darrell Spencer

IMHO, using a computer to point a telescope to find Venus in daylight is
cheating. Finding the RA/Dec, or Alt/Az is more like it. Finding it in
binoculars first is a great way to do it. Some people, (Derald Nye),
seem to have an innate ability, and I often invoke them to find it
myself. even when (manual) setting circles fail me.
My vision is insufficent, (so far) to detect Venus in daylight, but
I've managed to find all naked-eye planets through a finder scope and
main optics of my C8 in broad daylight-noon or so-from various observing
sites.

Venus is really quite beautiful when seen in a deep blue Arizona sky.

if you update the firmware as they instruct, you will have an inoperable
unit. Go figure. But when they work, they are a LOT of fun.
