 I would not look through a metre‐wide telescope at the Sun with naught but thin film protecting my eye. e: Eyes, plural. He’s using a binoviewer. With my luck, a bird would fly into it. Platystemon fucked around with this message at 04:42 on Mar 4, 2018 |

Platystemon posted:
The mylar films are actually pretty safe. The sun's energy gets reduced before it gets magnified by the mirrors and lens. Old style was to have a filter that would screw on to the eye-piece lens. Problem with that was being at (or close to) the focus point a lot of cheaper filters were getting burned out while people were looking through them - so I was told when I went to buy one for a new telescope.

In any case your eyes have a pretty decent aversion response to visible light even if a giant hole got put in it. It's not like a 100 watt yag laser that you wont know your retina is burning out until you eye fills with blood.

Girl critical after electric shock from tap while watering gardenquote:A 12-year-old girl is in a critical condition in hospital after receiving an electric shock from an outside tap at a home in Perth's northern suburbs. How does that happen? I guess it has something to do with a badly installed grounding cable on the water pipe?

Memento posted:Girl critical after electric shock from tap while watering garden Someone ties an electrical ground to a pipe near the faucet, ignorant of the fact that plumbing upstream is not conductive. A wire faults to this new “ground” but because it’s floating nothing happens (like a breaker tripping) till the kid completes the circuit.

Cable Guy posted:Mylars pretty tough, it would need a flaw you'd probably spot when you put it on the scope. If it got a simple tear I'm guessing it would probably be defused/defocused enough that you'd get away without eye damage... if the torn bit flapped off or away from the scope though you would be in trouble. if they use pvc instead of copper in parts of the plumbing

Cable Guy posted:Bolded bit... why is that? Well if they break a continuous metal pipe, plumbers are supposed to install jumpers to maintain electrical continuity to prevent this sort of thing from happening. But people don’t always appreciate the significance of this action so sometimes it doesn’t get done.

Thanks to this thread I am hyper aware of things I could fall onto and while doing....loving anything, Im thinking about ways poo poo could gently caress up. Like, that story told earlier in the thread where the guy was moving a toilet, tripped, it shattered and he bled to death from a thigh wound. Edit: Actually, I do have something to contribute. My step father used to hang steel buildings, in the 80s. Until he fell straight off a 2 story building onto his back. He lived, but he was hosed up for more than a year after. He missed landing on pipes sticking up by a small amount as well. ...or the time he hung an entire building by himself, while in an arm and leg cast. Mostly I gathered, from his stories, that it was pretty Wild West around here in the 70s and 80s. Johnny Aztec fucked around with this message at 18:16 on Mar 4, 2018 |

Sagebrush posted:What happens if the film tears while you're looking right at the sun? https://youtu.be/SjOTOUeERI4 I have one this size. You can see stars during the day it collects so much light. Not good view mind you. But I did only try it once for fun, because I didn't want to accidently swing it around. Hell the MOON is so bright you need a special filter, not dangerous just hurts your eyes. The moon is daylight bright when full. Note you can just put a small filter that threads into the eyepiece instead with zero chance of it failing, but you don't want your primary mirror heating up and warping. Before mentioned moon filter is on the eyepiece.  ask me about amatuer astronomy!

Sininu posted:Did that fence really stop the flow? Liquids flow around obstructions, yeah. As long as it has somewhere else to go. This flow probably only needed a short while to solidify and the fence gave it enough time to do that. Warbadger fucked around with this message at 20:31 on Mar 4, 2018 |

Bombadilillo posted:https://youtu.be/SjOTOUeERI4 It's possible to view a surprising amount of things with a telescope during the day. Venus is a particularly popular target for this. But Venus is always within 47 degrees of the Sun (usually less), and you really don't want to accidentally point the scope at the Sun, even for a moment. So the usual practice is to set up in the shadow of a building, situated so that the Sun isn't visible but Venus is. Ideally, you'd do this in the afternoon during a time Venus appears east of the Sun in the sky. That way the Sun won't rise over the wall if you get distracted for a while.

I usually wait til dusk and watch Venus while I let my scope sit out cooling. Good chance it will be a badass crescent. Mercury is always a badass crescent.

It's been thawing all day. In fact, it was thawing yesterday too, when people were warned to get off the ice ASAP. Today a local police corps posted this: https://twitter.com/POL_Charlois/status/970324703029223424 The police writes that the ice is very dangerous and that it took a lot of convincing to get that guy to come off it.
