Thanks for the response. It's a new scope, so I assume it doesn't have to be collimated. But what do I even know. I'm an amateur willing to learn.

Thanks for the response. I'm aware of the complexity of that task and I've bought three 5 inch glass blankets for 'training'. Hopefully one day I will be able to make a serviceable device. As for the magnification, a 203/1000 scope isn't enough for planets. I'm already using a barlow 2x and what I get is 222x (9mm eyepiece) what makes a planet like saturn or jupiter look quite small. I guess a magn. of 1000 is needed to get a satisfying view.

I've bought an 8inch Newtonian from Omegon with push+ but it's inaccurate and the magnification isn't great. Since I don't have the money for a new one, I wanna build a DIY scope from scratch. I've seen several videos and read about it. Do you have any tips for me? I'm planning to polish my own mirror after melting multiple layers of glass in a kiln. Many thanks!!!
