Hey everyone, I'm new to telescopes so I don't know too much. Might be stupid to build a telescope for the first one but I really want to and I'll learn better that way.
I posted for help about Aperture and Focal Length and settled on an 8 inch 1600mm so F7.88. Secondary mirror 30-38mm to keep obstruction under 20% but big enough to suit the whole DIY janky setup. Hoping this will be good for planets, moons and bit of other things.
I need help on the other parts . I'm having trouble using Newt for the Web as it's asking me things I don't know yet. Specifically the Focuser to Front of Tube. I don't know what the secondary mirrors distance is from the primary so I wouldn't know the focuser from the front of the tube.
That brings me to the focuser section. I don't know much about focusers, things like their diameter. I've marked the parts I don't know in red with letters. If you guys can help me out on this, that would be awesome!
If this stuff needs to be done after buying all the parts, what focuser would you guys recommend?
