Transit of Mercury - Hydrogen Alpha

Note the 5D3 has enough dynamic range to pick out surface detail on Mercury. Take that, Nikon owners. Actually, on reflection, take that, NASA  8).

Ok, I'l bite. =) What exactly are those of us not informed on "Transit of Mercury - Hydrogen Alpha" looking at and what gear did you shoot this with on the 5D3?

Transit means its path or crossing past the sun's surface as viewed from space.  Basically you're observing Mercury's orbital path around the sun.

Hydrogen alpha is a band of red light in the electromagnetic spectrum.  Hydrogen is the most abundant element in the universe and is the brightest wavelength that can be detected.  In this case, the OP is probably using a Hydrogen alpha filter to isolate the wavelength of Hydrogen.

I'd be interested in what equipment was used as well.

To me it looks like a slightly blurred macro picture of an illuminated piece of amber.

No matter what it is, I like the picture!  :)

The "blurred picture of an illuminated piece of amber" in this case is actually the outer surface (photosphere) of the sun in the background. 

Mercury is that small dark sphere in the lower left.

Doesn't look real to me.  Here is one of venus transiting the sun in the summer.  FWIW...none of us will see this happen again.  Its not do to occur again in our lifetimes.

You have a point woollybear -- it does look a bit suspicious.  Maybe a crop from an image taken with a 6" refractor?   Maybe not.  OP has yet to pipe up with any specifics.

BTW - nice shot of Venus's transit. 

The last transit of Mercury occurred on November 8, 9 2006.  The next transit of Mercury is due to occur on 
May 9, 2016.

Hi Woollybear, that is a fabulous shot. Any chance of getting hold of a high quality version of it?

Cheers Brian

Whoa...sorry about that...but this NOT my photo.  I would have given attribution but I have found at least four sites/photographers claiming the photo as theirs.  Near as I can tell the real photographer is Alan Friedman.

So what's in the shot?

Clearly it isn't a pic of Mercury - it would be a complete silhouette against the sun. Also if it were an astrophoto I wouldn't post in Abstract (along with the small disclaimer)!

I was cleaning out a jam jar with hot water and saw neat patterns in the dissolving jam as I swished the water around. It looked a bit interesting and I thought there must be a shot in there somewhere. Out comes the Tamron 90mm macro and the shot you see is an extreme crop to home in on an airbubble (hence you can see through it). Messing about in Photoshop with levels and colour temperature really amped up the oranges and yellows. The more I messed about with it, the more I thought it looked a bit like the surface of the sun and the bubble suddenly became "Transit of Mercury".

The shot that woollybear posted is excellent - just google "hydrogen alpha images" for more terrific images.

Oh, in case you're wondering, it was strawberry jam (very nice on a toasted bagel  :D).

Yep, a Fine Art print of it costs 950$. I'm hoping its possible to get a poster of it maybe?
I emailed Alan, lets see how he answers.
