Comet Machholz - February 2, 2005

  • Exposure: 15 min. @ f/4.0
  • Lens: SMC Pentax 300 mm f/4.0 EDIF
  • Camera: Pentax 67
  • Film: Fuji NPZ 800
  • Location: Ritter Butte, Oregon
  • Date: 02-Feb-2005 @ 21:15 PST
  • Scanned by: Tony Hallas
  • Notes: Pinpoint stars were a result of guiding on a stars; however, this shortened the exposure due to the comet's movement; a similar, but longer exposure can be found here; used a combination of Photoshop and PixInsight LE to bring out the tail and remove the vignetting.
