For complete collimation however, a star at night gives the best results if you donít happen to have a Hotech laser collimator.
I've tried looking at a reflection on a distant insulator but daytime reflections are difficult to see the supple rings each side of focus .

The other reason i need an artificial star is I've no EQ mount .
