I think there is a spring inside around the large central screw on the secondary mirror. I have attached a picture so you can get an idea what it looks like. It feels springy and if I turn it with my hand I can definately feel something springing around in there. At first that springing kind of scared me and I thought I damaged something but it seems normal now that I know what is going on.
Hmmm this is slowly making more and more sense to me each time I have a go at it. If nothing else I have learned a fair bit about how a Newtonian telsecope works.
In any case my secondary mirror seems to be the main problem. Aligning the secondary mirror actually seems quite easy. The secondary one is tricky to say the least. But alas I will not give up on this as I think this scope will be quite nice when it is collimated.
The scope itself is a Omni XLT 150, FL=750mm and a 150mm diameter so I figure that makes a F/5 scope. Unfortunately this means collimation becomes more critical for perfect viewing (or at least near perfect). Hmmm I am getting the impression that newbies should start with refractors (joking).
Anyway I will poke around with it again over the next few days and see what I can do. Eventually I want to take some snap shots of the planets, moon and maybe a few night sky objects. Though photography is not my primary objective with this scope I will be happy for a nice crisp view and at least ok'ish pictures.
