Night September 28th-29th 2011 |
| Camera |
: |
Nikon D7000 with battery grip to provide power for whole night shooting |
| Camera Settings |
: |
Cameras buit-in interval timer set to 37 sec intervals, ISO1600 and 30sec exposures; shooting started minutes after astronomical night began, and ended several minutes after it finished. OK, my stupidity ruined first 17 minutes of imaging.... |
| Telescope |
: |
Sigma 12-24mm set to 12mm set to f5.6 (Oh, if I had the 8-16mm lens, or a full frame camera for 12mm one :)) |
| Mount |
: |
Photographic tripod |
| Processing Package / Processing Applied |
: |
StarMax V1.6 for startrails and Photoshop Elements 2 for post processing. |
| NOTES |
: |
Session lasted almost 9 hours (I used photo bag with 5kg counterweight to stabilize phototripod against the wind, and after 17min of shooting I realised that spare battery for the second camera were left in that bag; getting them out put images before and after out of alignment and I had to discard first 17 minutes).
I was pleasantly surprised that two new fully loaded batteries after 9 hours of shooting had 45% of power in the second battery! Two (old) batteries for my 80D could last only 2 1/2 hours of such shooting. |
