Horsehead and Flame Nebula
Total 14 mins. 1 minute subs at ISO 3200. Borg 45ED (270 mm focal length with reducer) on Vixen Polarie, Benro Gimbal on Manfrotto 410 on Gitzo 2541 tripod. Taken in Makarora Valley, Wildearth B&B, New Zealand. Feb 2013. Lights acquired via Backyard EOS which was also used to check polar alignment.
No drift alignment was done. Alignment to the southern pole was using the Polarmeter compass adjusting for magnetic declination. Latitutde adjustment was done by using Samsung Galaxy Note 2 with an inclinometer app. Therefore unable to get more than 1 min subs without significant drifting. had to push to 3200 ISO which resulted in a grainier picture. Must use drift alignment the next time to get longer subs and lower ISOs.
