1-19-2008 Far red image of M42. Canon 300D infrared modified with filter to block light bluer than 670 nm. Although not photometrixally ideal, red pixels in the CFA see proportionally bluer light (670-1000) while the blue and gree CFA sees (~800-1000). In this image the red CFA layer is now blue/green, while the blue and green CFA layers are coded as red. Lots more stars are visible, looks like a 2MASS image. M42 infrared

New 2-24-2009 Photometry with my new toy - An InGaAs Near Infrared Camera from Sensors
Unlimited - model SU320-1.7RT-V/RS170. Not suitable for astronomy without some modifications (camera offset/flat correction turned off, sensor cooled below specs). It is a video camera that can only integrate 20 msec per frame. Extensive stacking procedures are
being tested (can get to Hmag ~7 at the present time). Preliminary photometry is promising.
More photometry from 3-1-2009

This camera sees from 900 to 1700 nm and can access the Y, J and H near infrared bands (but not K). Check out my Youtube video also to see what H band looks like on household objects.
