Dear All,

I am new to astronomy and this forum. I bought a second-hand Newtonian yesterday, a Megastar TS N 1400/150 with EQ-3 mount.

However, it did not come with any manual and I hear that Newtonians need collimmation adjustument and I do not know how to do this.

Does anyone have a link to download the manual or PDF copy?

Regards,

QuietLeni
