Omega Centauri - First test shot

The T-adaptor arrived from scopestuff this week so I am finally able to attach the Nikon D70 to the LX90! I searched high and low for a t-adaptor of the 'short' variety that would ensure the camera clears the base of the fork arms. This one does it by a whisker, but wouldn't clear it with a focal reducer attached.

In spite of the moon, and my neighbours father who wanted to see what all the fuss was about, I decided to try it out tonight.
Alt-azimuth alignment, no guiding and had to rely completely on the accuracy of the go-to because Omega Centauri was nearly overhead so the camera was lost in the fork mount and I couldn't check through the view finder to center it! If nothing else, this shot is testimony to the accuracy of the go-to!

Single shot, 30secs at 400 ISO (I meant to use 800 but forgot to change it, @#$% neighbour chewing my ear off!). Focussed on the moon then slewed to Omega Centauri. Levels tweaked a little in Photoshop.

I'm quite pleased with it. Next time, with no moon, I'll take a series of shots at ISO800 or 1600 and stack them.
