It's been a while since I posted in a forum so I apologize in advance for any formatting mistakes.
So, I was planning to build a modified version of the popular star projector designed by CanYouImagine and wanted to know if you can help me identify a key part of what makes this projector actually look good compared to other cheap star projectors.
As you can see in the video, the stars projected are different from your typical "star" laser head. They've different sizes and a more random scatter.
The star projector uses a green laser diode with a "beam multiplier" filter (I don't know how it's called, if someone knows I like to know the proper name).
After that, it uses your typical rotating disk that is more common in cheap star projectors for the moving star effect.

Picture of the projected stars WITHOUT the rotating disk filter
The filter that is attached to the diode is the one that I'm looking for as it's the one that makes the stars look more "authentic".
The DIY version that I want to make would have different laser colors switchable (405nm, 488nm, and 532nm). Also, it would have a laser lumia aurora or maybe a LED RGB aurora/cloud.
The only part I'm missing is that star filter. Common sense tells me that it's custom and not commercially available, but I don't even have the proper keywords to look for it. If someone knows about this please let me know![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
Please post your questions or criticism about this modest project.
Cheers!
