They look like pretty typical darks for the ASI294. I had one before I went to an ASI2600 and the darks form it looked the same as that, and the ZWO web page for the ASI294 showed the same. A master dark made from a good number of darks should subtract out the starburst from light frames nicely.

This is a 300 second master dark from my ASI294.
