Xmas has come early! Seeing conditions would have to be 9/10.

I made a quick extension tube to go in my other extension tube, so god knows what FL & mag I'm at now. :confuse3:

This is a stack of 250. My reflector is in bits at the moment, adding a slo-mo control to the DEC axis & hopefully I'll get mars with it before it gets too low.

You up early to try for saturn Slice or have you been up all night? Seeing has turned to mush here so I might dip out on saturn, damn it.

couldn't sleep...I've an earache. Not game to stand outside for too long.

Visually, the stars look pretty sharp here, low clouds are starting to form though.

Hope your ear ache clears up soon. The seeing just went from mush to perfect in the space of 2 mins. Wish it would make up it's mind! I think I got some pretty good AVIs.
