Centaurus A and 47 Tuc

Hi,

A couple of photos from last night I took with Michael (Tilt).

We used Michael's WO focal reducer with the 140 Neoachromat and a Baader UHCS from downtown Canberra and the unmodded 350D. (camera control via images plus and straight into deep sky stacker).

The exposures were as follows:
Cent A: 30sec x 40 with ICNR. ISO 1600
47 Tuc: 30sec x 12 with ICNR ISO 800

Bit of tracking error at 640mm fl. An autoguider would be nice but not bad for a first effort.

Cheers
David
