The Wide-Field-Telescope (WFT) is extremely well
suited to generate some of the best wide-field astronomical images
in the world.
Here are the key reasons:
- 1 metre clear aperture
- An extremely large and gapless FOV of 5 square degrees
- A very fast f/2.4 optical system
- Highly corrected FOV with 80% of the energy focused into one
- Negligible vignetting, less than 6% in the extreme corners
- Extremely dark sky of 21.90 mag/arcsec²
- Extremely high QE - 93% ast 550nm and 60% at 900nm
- Large dynamic range with 90,000e- well size and 16 bit sampling
- -100°C cooling - no dark frame needed
- Downloads in less than 2 seconds
These factors and a few others allow the WFT to
produce extremely deep and wide images. We believe will be the
best wide angle images in the world.
For example the Triangulum Galaxy could be imaged
down to mag=27 in three colors in 15 hours. And this is with FOV
of 5 degrees²!
The WFT could image the entire sky to magnitude
21.5 twice per night with the wide band filter (400-900
nm). This ability would allow the WFT to find a dozens supernovae
