Hi, I have used ASI Live a few times with my new ASI camera, and I like it a lot. Very intuitive interface. I have a lot of prior experience using Starlight Live with a Starlight Xpress camera. One feature that SLL has which I think you should add to ASI Live is non-linear stretch. SLL has two - fourth root (X 0.25) and inverse hyperbolic sine (arcsinh). Both provide significantly better, brighter, more contrasty live stacking views than the linear stretch does. This is just display processing math so hopefully not too difficult to add. Thanks for the great free software!
