Oh dear, uploading that image to the forum has compressed it to death

So here's a link to the original:

The original is worth the look. Love the those fast Epsilons!

really nice larger image there

[AstroGZ]

Fantastic image there, great colours!

Great result, clear image but the bright stars are squared...shame, the image is worthy! 

[sharkmelley]

The square stars are a typical "feature" of the thick spider vanes that hold the secondary.  It might be possible to reduce the effect slightly during processing.  It affects observatories as well - I've seen some excellent pics from the European Southern Observatory that have similar square stars.

Who needs a high end CCD camera anyway....?

This is just insanelly beautifull! I'm a reflector guy and love those long difraction spykes, the Epsilon really sings

Congrats on such a fine image!

sorry I didn't  know of this feature, I thought it belonged only to Vixen Visac...

OK, square stars are a problem but surely this is still a great image. Facts of life.

Who needs a CCD camera? Anyone wanting to go deep with a slower, diffraction spike-free refractor. At least that might be one answer.

But this is a super piece of work with quite a tricky telescope.
