Test of LPS and coma corrector on the Keyhole Nebula

Well, it's a full moon, but we can't let that stop us. The Baader Planetarium MPCC coma corrector works a treat. Only the inner 50% or so of the image was usable before! Wow! I don't know if the Hutech IDAS Light Pollution Suppression (LPS) Filter worked at all, but it was already screwed on anyway because of the 3 street lights shining on my telescope. Made for difficult color correction though. Did it the way I like it as though it were viewed through a really big scope so no Hubble like fake colors or messing with the stars. The seeing was atrocious too. A week ago I could clearly see the Cassini division on Saturn's rings, but no way last night. I've only done half a dozen deep space shots with the telescope and camera, so I'll keep practicing.

Slewed over to another target after this 50 minute run to find the focus had changed - There was ice on the scope and it was getting colder by the minute.

Here's a pretty piccie.
LX200 10" f6.3 with Canon 450D hoping it clears the forks every time

2nd image is from 3 months ago without coma corrector or LPS. (And only half the exposure time.)
