amazing blue recording ability of the 10D is illustrated in this
image, a mere 10 minutes of integration time with my 12.5 inch.
Even with an hour and 20 minutes of exposure, my ST8I didn't
show this much field nebulosity. Although my camera is not cooled,
it was near freezing when I took this image, lowering the noise
even more. This object represents a loose but close to us open
cluster, surrounded by dust. Another very important point about
this camera is that the CMOS does not bloom. This image would
be a bloomed nightmare with my ST8i, long streaks extending from
the bright stars in both directions to the edges of the field!
The problem of course with giant wide blooming spikes, is you
must fill them with something when you repair them. ||
