Hi - if you have triangular stars then it is likely the mirror clips are too tight. After fitting a mirror mask on my SW 150 I ended up with a small gap so no pressure at all. For fine collimation I found a tri-bahtinov mask a lot easier than say star testing. You line it up with the primary mirror screws which you adjust to centre all 3 patterns (on a bright star). Only takes a few minutes for perfect collimation. Your guiding sounds phenomenal. Good luck with it!

Thanks Ray, I had tracked it down to pinched optics with a little internet research, removed my primary loosened my primary mirror clips, then re tightened to a lesser degree and reassembled earlier today. I havent been able to test yet. I shall def look into the tri batinov masks. Much appreciated!

I have the same scope through Highpoint Sci. It's marketed 'Apertura'. But like yours, It is just a relabeled GSO. I was lucky enough to get this scope when it was on special @US$ 300.00 And at that price it'd be impossible to beat. But it definitely has a handful of issues right out of the box. The mirror is pinched as mentioned. And when you loosen it up, it can slide around on it's back. So that'll have to be addressed as well. I also plan to replace the spider with a solid cnc version. Good video. Keep them coming

Thanks Mike, Overall I was impressed for the price with everything but the spider, I've got some knurled knobs coming to maybe make it more bearable, but at this rate of no Stars in july so far, I think its artificial star time. If I end up with the CNC spider I'll certainly do a video on it. I actually tried to find the apertura version first oddly enough.
