Im taking ms physics and i want to specialize in astrophysics but we have no large telescopes within our area (actually, we have, in our university, but we have to be scheduled and the fees are a bit expensive for me to be use it frequently). I have read some articles in the internet how to build a dobsonian telescope and I decided to build, i think, a 25" or larger? or small one first like 13" or a bit larger just to see deep space objects. Well, In terms of financial status, Im just in the middle class but Im determined to gradually finance making it. FYI, im also an engineer and there would be not much problem building its parts that I know how to build. But is it preferred to build my own?
