Hi All
I've been reading this forum the past couple of weeks and have learnt so much around refractors, reflectors, eyepieces etc (thanks all)- however i ignored the advice to purchase a Dob and went for below

For a complete beginner it's fascinating what can be seen with it, so more than happy.
I'm getting to grips with the mount and probably me being thick however i have one question - do you know what this knob is for in the attached image. In the basic instructions it says 'horizontal adjustment knob', however if i turn it nothing happens - it just unscrews? There is another on the opposite site, again exactly the same.
Many thanks
