This nebulous cloud of gas (IC 410) and embedded cluster of stars (NGC 1893) are found in the constellation Auriga. They are perhaps 12,000 light years away. As an image, the scene presents wonderful contrasts: the bright red, hydrogen emission tadpoles in the lower left; the purplish glow of ionized hydrogen and oxygen in the larger nebula; the light-deprived dust clouds in the upper part of the image; and, spread out across the scene, are the stars that have formed from the very gas in this cloud on this side facing earth---a brilliant spread of jewels on purple velvet.
This is my third observation of IC 410 and NGC 1893. The first is
here, just an h-alpha take with a smaller scope. The second is
here, a close-up on the tadpoles.

Amazingly beautiful. Almost surreal. I like how you oriented the diffraction spikes.
Thanks, Rory! About the spikes: Really? I have been noticing diffraction spike placement lately. I sort of like up and down, too. Also, a problem with diagonal is that I don't think I can duplicate the angle consistently. And diagonal means my guide camera is not orthogonal. Up and down solves all these problems.
