SBIG - Research STL-4020M Camera

Designed around the KAI-4021M progressive scan interline CCD, this is the big brother to the popular ST-2000XM.  With 4 million
pixels and twice the imaging area of the ST-2000XM, this camera packs a lot of punch for the price and is our entry level large
format camera.  The small pixel size and superb anti-blooming characteristics of Kodak's interline parts make this an ideal choice
for wide field imaging through short fast refractors.  The QE is very high in the blue and green compared to other interline parts
from other manufacturers.  Compared to Kodak's full frame sensors this CCD is less sensitive in the red and slightly higher in the
blue/green.
