2012 Venus Solar Transit, June 5-6 - Page 2 - Orbiter-Forum

Gerdih · 05-05-2012, 04:58 PM

If I can I will try to do something with a paper and my telescope but I see Im in the limit of the visibility. Moreover 5 or 6 are not on a weekend.

I wonder if I can directly take a picture of the sun during the transit using a neutral density filter on my lens.

Yeah, you did (website is down

). Pray for the probe to bring it back online.

If an orbinautor does make a picture, hope posts it here also.

Update: Probe works: it's back online...and still broken

Checked it in Stellarium, it seems to be nearly correct.

Weather for next week is looking bad right now, but I purchased some filter foil to build a filter for my telescope.
If weather is bad I'll try to find a good place within the next 100 km. If not... well, I saw the 2004 one...

I had a pair of eclipse glasses, but I don't know where they are. I want to try and make my own solar viewer, and a pinhole projector seems the easiest option, but I'm concerned that aiming it correctly at the sun will be challenging.

Which is the cheapest, easiest, most satisfying and least injurious way to view phenomena such as transits and sunspots?

The best way I've found is to use a telescope or binoculars (with one side covered) to project an image of the sun onto something. No modifications necessary, so no extra cost.

Here it will happen from sunrise till a few hours later.
Did a dry run and location reconnaissance today.

My windows turned out to be on the wrong side, and there is a building on the right one, putting the roof is out of the question too.
So, i go for a nice view from the hill.

The idea is pretty simple - project the image directly from the scope+barlow lens onto a screen, put a tent around it all to keep all the image-obscuring light out, observe.

The sun lazily crawls up, looking like someone sat on it.

Once it's high enough, the image becomes pretty clear (but not the photo - i didn't have a spare tripod since i didn't really plan on taking pictures this time).

You can clearly see some sunspots, and they are even visible in the crappy photo.

An SDO image for comparison, mind the mirroring

Looks like everything is ready for the event, i'll post the pictures if the weather doesn't foul the plans.

Those cheapy eclipse glasses that resemble old school 3d glasses is probably the easiest. Those things are very cheap, and most telescope, museum, science stores carry them.

or some welder's glass. that is quite cheap. Not easy to find shade 14, Will probably have to find an actual welder supply to get those, but it is quite cheap, easy , and perfectly safe.

We've got an east coast low forming at present...Those things are notorious for hanging around all week long in winter and blanketing the length of the New South Wales coastal lowlands in drizzling rain and overcast - that eliminates the prospect of avoiding it by travel within any reasonable distance. This one is looking no different
