A very simple artificial star for collimating my Celestron 8.
I use a thin coper plate with a very little hole, for this i use a needle to create a little dent ans use a very very smooth sand paper to sand the dent side. It's the same technique for create a stenopé. For the 1/4 mount i use 3/8-1/4 adapter. The button is 9x13mm.
For the power i use a 9v battery.
