If thats a single frame, i really cant see what your complaining about.
But you need to add gain, so i recommend you read how its done.
This is from the QHY-10/12 manual..
Setting the GAIN and OFFSET
Usual Calibration Method:
1. Set the Gain=0
2. Set the exposure time to 0 and cover the lens-this
is a BIAS frame .
3. Watch the local average of the captured images
(can use the Noise Analyze function of EZCAP)
4. The ideal average value is around 500 to 1000. If
the value is higher, then you should reduce the
OFFSET. If the value is lower then you should
increase the OFFSET.
5. Repeat steps 2- 4 to obtain the ideal OFFSET
Note A: For some QHYCCD products when you
use bin modes of 2x2,3x3,4x4, images may
reach 65535 even with gain set to 0.
6. Open the lens cover and increase the exposure
time. Use a uniform light source, such as light
boxes or an LCD screen, and take a saturated
exposure of the image.
7. Watch the local average value of the captured
images if the value is is less than 60,000, you need
to increase the value of GAIN, if the value is 65535,
then reduce the GAIN .
8.Repeat steps 6-7 to obtain the appropriate GAIN
9.Under the GAIN, repeat steps 2- 4, and obtain
more accurate OFFSET.
See if this helps you.
