Taking pictures on an alt /az tracking mount

I thought i'd share this shot of Eta carina taken with a sony NEX5 attached to a skywatcher ED80 mounted on an ioptron cubepro alt/az tracking mount. The mount was roughly aligned and only synched on the moon which i was taking pictures of that night.Just as an experiment i centred on some stars taking long exposures at iso12800 and was pleasantly suprised at the results, nice round stars at exposures of 10- 15 seconds . Armed with these results i centred the scope on the eta carina nebula and took some shots at 20seconds exposure , one of which is shown below.

PS no darks, flats etc and the original was 14Mps
