Hi Bernard,
Don't feel discouraged. Like anything worhtwhile there is a learning
curve.
What you might try as a start is just piggybacking hte Camera to the
telescope and using the longest lens for the camera you have. The
telescope can provide the tracking and then the Camera the imaging.
The hyperstar adds some complexity to the system.
Once you have taken some images that way, then advance to using the
telescope as the main objective for the camera. BTW, I have has some
experience with the hyperstar system, but did not know you could use a
DSLR CCD camera with it. I thought you needed as dedicated astro
camera. Because the camera in in front of the telescope with hyperstar
that is a fairly large obstruction.
What do you see as the evidence of problems? What are you trying to
image? Be aware objects like M31 and M42 are very bright and you can
over expose easily. M13 is a good deep sky object. The Moon and
planets will be too bright for your system unless you take some
measure to reduce the brightness.
Do not worry about darks, flat field or bias until you get further
along. DSLR cameras do a good job of imaging with minimal effort on
your part. Until you have more experience most anything else youdo you
are just most likely going tomake the image worse. Everyone goes
through that stage.
Tell me more and I will try to help.
