Building A Newt

[Some Dude With A Mak- Cass]

I am building a newtonian reflector telescope, and I could use some help. This is my first DIY telescope, so I am pretty unprepared and don't know where to buy some stuff, namely optics. I am planning on going for a 8" aperture, but I can't find a website that sells mirrors. What website or sites has good quality mirrors but isn't to expensive, and what mirror coating is best? All help is appreciated, thank you in advance!

Hi. These guys do mirrors in all sizes but you end up paying the same for the mirror as a complete telescope. All the ones I've seen are Al coated by SiO2. HTH.

I know Teleskope Express sell mirrors and all the other telescope bits you'll need, you could also check out Orion Optics for the mirrors but I think they're quite prices from there.

What I would do is keep a look out for a secondhand one from astro buy and sell or maybe e-bay.

Hi  The cheapest way is probably a second hand mirror from SGL or ABS web sales pages.

If you are a bit more confident. Then what about grinding your own mirror from scratch.

If you start a post on SGL you will get plenty of help from the members on this site who have experience of grinding their own mirrors.

I hope this helps☺
