I have used a shiny round christmas tree ornament on a film canister in my yard , reflecting the sun, for rough collimation after a reassembly on an SCT during the day.

I have also tried a pin hole in a film canister with bright light inside or beaming a laser measure through an eyepiece at a target. The shiny ornament worked more easily.

For complete collimation however, a star at night gives the best results if you don’t happen to have a Hotech laser collimator.
