10/25/2007, 10/29/2007, 11/02/2007
10/25/2007 and 10/29/2007 with chart
10/25/07: 32 15 second exposures at ISO 800
10/29/07: 58 15 second exposures at ISO 800
Notes: Stitched together to show how the comet changed in appearance and position
between 10/25 and 10/29.
10/29/2007
Telescope: 120mm f/5 refractor (fl=600mm)
Camera: Canon EOS-10D
Exposure: 36 7sec exposures at ISO 1600, stacked using Registax
Comet C/2006 M4 (Swan)
Swan - 10/31/2006
Telescope: 120mm f/5 refractor (fl=600mm)
Camera: Canon EOS-10D
Exposure: 50 15sec at ISO 1600, stacked using Registax
Notes: When these images were stacked the comet was used as the
alignment feature. This causes the stars to show up as trails as the comet
has moved relative to them in the time from the first exposure to the
last.
Swan - 10/27/2006
Camera: Canon EOS-10D with lense set to 183mm, f/8
Exposure: 21 30sec and 5 2min, at iso 1600, stacked using Registax
Swan - 10/25/2006
Telescope: 120mm f/5 (fl=600mm) refractor
Camera: Canon EOS-10D
Exposure: 129 15 second exposures at iso 1600, stacked using
Registax
