Night Sky Images - 25/10/2021
Clear for most of the night. After successfully using the tracker a week or two earlier I managed to get hold of a remote shutter release cable to allow the tracker to automatically trigger the camera - my previous testing was several manual shutter release image (I don't have an external intervalometer at this point).
I took two different images of the night sky - roughly pointing in the same direct, just at a different elevation; one at tree-top level, the other almost vertically up.
Gear:
- Canon EOS 200D
- Tokina AT-X Pro SD 11-16mm f/2.8 (IF) DX
- Tripod
- Star Adventurer 2i tracking mount (with shutter release cable)
Weather:
- Clear (zero cloud for most of the night)
Location:
- Garden
Software
- Rawtherapee - RAW file importing, optical correction & image processing
- ASTAP - Image stacking / general astrophotography toolset
- GIMP - RAW/TIF to JPEG, cropping
Images
First image was taken from a sequence of 5x 30 second exposures at ISO 1600. This was my usual 'at the tree tops' image composition for the garden.
The second image is comprised of 6x 120 second exposures at ISO 3200. Something that I could have technically done without the shutter release cable, but not something I'd want to stand around counting down and pressing the button for; the app for the tracker did it all brilliantly.
