Decided to try imaging with the Nikon D5100(stock) once again for the larger field of view with the RC8. Looks like the collimation is off in this setup compared to when the ST2000XM is mounted. Both camera are hard mounted to the ONAG, so I am not sure where the tilt is happening. Unless it is because of the weight difference, but I am not really sure about that.
Besides the above, this is my first attempt at a HDR technique in PixInsight. Prior it was many years ago with layers in PS. Pretty happy with how this turned out still since the data was taken over a few hours with a quarter moon still up and from my red zone backyard observatory.
