I love this technology.
And although my setup is nowhere near as advanced as that, I still love using my 589nm for star pointing and my 532nm pointer on my telescope.
In my setup below I use my small telescope to guide my big telescope so as to be able to get nice sharp images too.
It's a bit different than projecting your own guide star with a 589nm laser but the idea is that the small telescope is hooked up to a computer which 'watches' a star and it's instantaneous movements through our atmosphere and makes tiny corrections on my big telescope's drive unit hence giving me a sharper, better corrected image.
Here below is the Veil Nebula (west) NGC 6960 taken from my back yard !
Like I said I love this technology.
Awesome Takahashi TOA 130NS setup and mount -- while not inexpensive, it is a very high quality kit and good value for money spent.
Great images---really nice shot of Veil Nebula.
589nm for sure makes a great looking star pointer
