Comets

Comet ASASSN (C/2017 O1)

Average Combine

Median Combine

Trail to show comet path

Date: 9/30/2017
Camera: Canon Rebel T4i
Telescope: 110mm f/7 ED refractor (Orion)
Exposure: 30x5min (2hr 30min total) at ISO 800

Comet Lovejoy (C/2014 Q2)

Comet Lovejoy with M45 (The Pleiades)

Date: 1/16/2015
Camera: Canon Rebel T4i
Lense: Tamron 28-300 set to 59mm
Exposure: 26x60sec at ISO 1600 and f/5.6
About: This image turned out quite noisy due to conditions and a late start (fewer frames). Still the tail is faintly visible all the way to the edge of the frame spanning at least 8 degrees

Comet Lovejoy (C/2014 Q2)

Average combine

Median combine

Date: 01/09/2015

Comet Lovejoy (C/2014 Q2)

Date: 12/30/2014
Camera: Camera: Canon Rebel T4i (modified)
Telescope: 110mm f/7 ED refractor (Orion)
Exposure: 74x30sec (37min total) at ISO 1600, stacked using DeepSkyStacker
Software: Images aquired using BackyardEOS, Processed in DSS and Gimp then resized with IrfanView
About: The above photo does not do this comet justice. Bright moonlight and the lack of guiding due to a mailfunction made it difficult to capture good detail. Hopefully I can update this image after the moon has waned.

Comet 17P (Holmes) - exploding

Around 10/24/2007 Comet 17P (Holmes) suddenly brightened. It appears to be exploding.

11/12/2007



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


Swan - 10/24/2006


Two focus-test exposures stacked before clouds rolled in

Machholz - 1/9/2005

Canon EOS 10D multiple 30 second exposures at ISO 800 and 1600
Stacked with Registax using the comet as the alignment feature

Machholz - 1/13/2005

Canon EOS 10D multiple 30 second exposures at ISO 800
Stacked with Registax using the comet as the alignment feature


Same images as above only the stars were used as the alignment feature
