Some photos of the transit of Venus from my front yard setup. Camera quality limits the quality of the image, I can see well defined sunspots too.

Triton to the rescue again!
Ooooh, nice. I only had a pinhole, and I thought I saw something but wasn't very good. Was going to use a welding helmet to look at it but it seems my filter isn't dark enough.
well done
now all we need is the time stamped series from across the day :)
No time stamped series but this is the end of it...:)
You can see the sunspots in some of those photos too.
Thanks Mic, my wife was disappointed as we only had heavy cloud cover and rain today.
I'm happy to wait for the next one. 2117 I think :D
Checked several times today using arc welding helmet.
Couldn't see anything. :C:no::~.
I'll wait till nex time too.
Regards, Keith.
Kept herself clothed here too.
Cheers,
Jim
:2tsup: Nice bit of a set up simple and effective.
Makes you wonder how they did it way back when Cook sailed the world to see it. If these icey winter winds are anything to go by they did it hard.
Certainly had a more stylish instrument, (a Gregorian reflector - not a refractor). They were in the tropics too, and were in Tahiti for several months, and if the old Mutiny on the Bounty movie was anything to go by, there would have been many "pleasurable" encounters with the young natives. Certainly a better experience than the prickly end he met a few years later:;:Uhttp://www.sydneyobservatory.com.au/...-telescope.pngQuote:

Well done Mic!!:2tsup::2tsup::2tsup:
I don't know about you fellows but I have watched som interesting spectacles in my time:
Nueman's Comet
Halley's comet
The explosion in the Magellanic clouds at the time Halley's comet was around. I happened to be outside stargazing at the right time.
Schumacher- Levy and its breakup.
The first footage of the Erruptions on Jupiter's moons
The alignment of the planets last year
The tansit of Venus this year
A full moon from the back of a school busQuote:

What's the purple roddy thing doing :?
That's a small 5" truss Newtonian telescope. Perfect for solar viewing as it doesn't gather a lot of light so less heat on the eyepiece and it's air cooled...Quote:

Is there a disadvantage in general to the truss construction? If so, why are the big ones done that way?
Puzzled
The big disadvantage of smaller truss telescopes is stray light, if you live in the city. In the country they are fine. Observatory telescopes are protected from stray light by being remote and/or in an observatory.Quote:

you can always wrap the truss with stiff black paper to cut down stray lightQuote:

I saw Venus in transit again today...:q
Now you're just taking the pith:DQuote:
