It was a cold night and a late start, the scope dew heaters stopped working, the 12V power supply blew up and my backup batteries were not fully charged but the sky was so clear and dark, with less than 3hours of battery life available I imaged Eta Carinae and Omega Centauri then setup for a few hours of manual push to viewing .

Congratulations, Wayne ! They are very nice. Eta deserves a more fine treatment to highlight his inner details.
Good work with DSLR. Despite of guiding lack, 15 sec subs were good choice to produce a good shape of the stars.
