Thanks. I had a go and used the laser. Collimation of the laser was ok (followed videos about rolling it while watching it on a wall /X marks the spot).

Collimation of scope seemed to go ok, laser adjusted in the middle of the dot on the mirror and was then in the middle of the laser eyepiece.

One thing I am unsure on, and if it's related is I can't seem to get good focus. I have good focus range; aka can focus right in until i see the spider/circle in the star and also focus right out. But that middle spot never seems crisp. I even tried with a bahtinov mask. With my refractor I could get stars as pinpoints and a bahtinov would give nice sharp spikes.

I took a couple of exposures and the stars seem odd. I'll post a picture tonight when I'm home from work. Could poor collimation cause this?


*edit. Managed to grab a crop of one test image I took. 300s exposure, iso 1250. Uploaded.
