New Canon 20Da !!! for you IR nutz out there

just announced!

The new Canon EOS 20Da seems to be almost identical to the Canon 20D, accept for features like 'Live View' mode which enables the user to manual control the focus by using the LCD display. This is very handy when using the Canon 20Da for astrophotography. The subject can be viewed enlarged on the LCD display (5x or 10x magnification). Furthermore a special filter that normally is used to block infrared information is removed. The Canon EOS 20Da is equipped with a more transmissive mirror which makes the new Canon 20Da 2.5x times more transmissive compared to the Canon EOS 20D. The Canon EOS 20Da is compatible with the timer remote controller Canon TC-80CN3. This accessory enables long exposure times especially for night shots or astrophotography.
Canon EOS 20Da major features are:
- CCD: 22.5x15.0mm
- Canon EF lens compatible
- CompactFlash type I and II slot
- 8.2 effective Megapixels
- JPEG and RAW (12bit) format
- Highest resolution: 3504x2336 pixels
- Lowest resolution: 1728x1152 pixels
- Color space: sRGB and Adobe RGB
- Interface: USB 2.0 Hi-Speed and Video out
- ISO 100, 200, 400, 800, 1600 and 3200
- Shutter speed: 1/8000 - 30 sec.
- 1.8-inch TFT LCD display - 118.000 pixels
- Li-Ion battery
- Dimensions: 144x105.5x71.5
- Weight: 685g

You neglected to mention that the 20Da is, as of yet, a Japan only modle.

And you need to add an IR filter for normal shots to get the best results.

AND companies have been remove IR filter from cameras since the D30 WAS RELEASED ;)

last month I found a site selling Dreb's and 20D's with the filters removed(and some other filters added even) on a astrophotog site. I KNEW I should have bookmarked it too ..GRRRRR

The manufacture (modifier) of the Canon Rebel, 20D, and Fuji S3Pro is Huetech http://www.sciencecenter.net/hutech/index.htm

Is the modified camera that Hutech makes different from the 20DA that kafin8ed posted? I thought that the 20Da was manufactured by Canon.

Thanks for the link, by the way. That's a good site to know about. I'll have to add them to the links section and the reviews.

Take a look at your avatar and profile - don't you mean Laguna Niguel? :p

Your right (Laguna Niguel). Anyway, the camera modified by Heutech is different than the one to be relased by Canon. Canon will use some type of modified IR filter which will allow 2 1/2 times the sensitivity to H-alpha. This is important to astrophotographers since most emision nebulae are rich in H-alpha. The standard cameras block this band. The Heutech version takes a standard camera and removes the filter completely and replaces it with a substitute to keep the optic path corrected. I think this increases H-alpha sensitivity by 4 times. Note that dedicated astrophotography CCD cameras are about 10 times as sensitive but need color wheels, multiple exposures, and Peltier cooling circuits (not to mention costs $3-6k).

The 20Da is geared toward the astrophotogreapher in several ways that may be unimportant to the "terrestial" photographer. One can focus on the LCD with the mirror locked up. This makes for live focusing which can save a lot of time in the dark. It also has improved noise reduction at high ISO and long exposues (in the range of 5 minutes or more). I'm told you will have to add an IR filter to correct the camera for day use. The Huetech version has an assortment of filters that can be used to enhance the imaging for astrophotography and correct for day use.
