Hmm, isn't the relativistic effect you are talking about (lensing I persume) highly dependent on the distance to the lens (Gauss lensmaker formula) ?!

Now for some one to answer, what would the composition of a black dwarf be.  I'm thinking carbon perhaps crystalized carbon--diamond maybe--any thoughts.

Astronomers came across a crystallised white dwarf that has a diamond composition last year. They nicknamed it Lucy after 'Lucy in the Sky with Diamonds' by the Beatles.

Looks good to me, and I like the red dwarf, too.  Unlike too many "really red" dwarfs this one looks about right.  Even the cool ones are as hot as in incandescent bulb, and should be about the same color.  Good job!

I had to clean my screen to see the black dwarf.  Under the light at work the dust looked about the same as the stars, and the only way I could find the BD was by scrolling the picture to see which parts moved.  Most of the "stars" were actually dust, and your starfield looks appropriately sparse.  This is probably as close as we'll get with today's knowledge...

Hi Betelgeuze, you pulled this off absolutely brilliantly.  I had to download the fella and increase the brightness to find the puppy-when I did it was superb.

Hi Conor, thanks for the website.  Looks like black dwarfs do exists--well at least Lucy does.  That be one heck of a diamond-4000km in diameter and somewhat larger than the 530 carat Star of Africa (largest diamond on earth)-some 10 billion, trillion, trillion carats. Jan

Im very happy you like it, Im also going to post it in the gallery.

Its realy hard to see the blackdwarf when you are in a room with a lot of
light, I made it at night so it was easy to see when I made it.
