Best wishes to you and yours for Christmas and I wish you all clear dark skies for 2007.

Lovely detail. Top drawer image.

Merry Christmas to you both!

Very good image Dave!
What's amazing is the FOV of the camera! Tiny!

Yes - precisely 5.2 * 7 arcmins at a focal length of 2426mm. Jusy shows you how well the AP tracks. Anything above a focal length of 2000mm is serious stuff for head-the-balls

Now, I just need to take off the reducer, slap on the 2.5 PowerMate and I'll be imaging at a focal length of 9625mm with a FOV of 1.3 * 1.8 arcmins :shock:

I have to say I was surprised at the detail I got considering the ludicrous undersampling (0.73 arcsec/pixel). But with the Hyperstar on the way, I'm hoping to redress the balance using the Fastar capabilities of the C14.

As it happens, the dimmest confirmed mag I have is 16.6 for an asteroid I was watching for the MPC on Friday night. I'll see what 2007 brings. But you can all be rest assured that MPL 2006 XD2 is being watched by Celbridge - you can all sleep comfortably on Xmas eve knowing that a few billions of tons of rock aren't going to slam into your garden and ruin it all

Jeepers, I need to bone up on my volcabulary before I read this thread again. :shock:
I think I understood some of the two letter words.

Anyhow, I thought it was actually a nice photo.

If I had a criticisim, it would be that I'm not sure your Losmandy diffraction mags aren't a bit hyperattenuated at the margins of the apochromatic extents, toward the edge of the eye-of-the-needle FOV, even allowing for the slapping on of the uncollimated goggles and the effects of a recent or forthcoming Friday night.

Merry Christmas
