WEBCAM PHOTOMETRY
I have recently (September 2004) started to investigate more seriously this aspect of astronomy. Making precise and accurate photometric measurements with a CCD camera is challenging aspect of the hobby for an amateur and using a webcam instead of a commercial CCD astrocamera brings its own additional problems. As a beginner in photometry I have a lot to learn and I am also finding out more about the characteristics of my webcam based camera. I have discovered though that it is possible to overcome the limitations of the webcam and make useful observations. I hope what record here will encourage other webcam owners to try their hand at photometry.

Feb 2006 |
Using photometric V,R filters An opportunity to compare my results with others as well as hopefully contributing data of scientific value |
|

Oct 2005 |
A few days after it was announced - egress only |

Sep 2004 -Jan 06 |
These are my contributions to a light curve of this Supernova, produced by members of the Unconventional Imaging Group QCUIAG |

April 2005 |
Observations of this star in outburst showing probable superhump variations. |
|
|
Jan 2005 |
A tricky observation - the jury is currently out as to whether or not the results are meaningful. |
|
|
Nov 2004 |
A convenient short period binary to practice on. |
|
|
Sept 2004 |
My first serious attempt at photometry. I took a series of images and then had to find out what to do with them - a real baptism of fire! |
|
|
March 2003 |
Not exactly precision photometry - just an on/off detection but an interesting project and I was pleased to get a result |
|
|
Oct 2002 |
I knew absolutely nothing about photometry when I did this and so ended up "reinventing the wheel"! |
