Advantas:

Because The Cost Of Refctors Is Much Lower Than That Of Nses, For Lar-Aperture Tescopes, They Are Often Made Refctive Rather Than Bulky Refractive. The Portab Design Of The Refctive Tescope, Although The Ns Barrel Is Only 500Mm, But The Focal Ngth Can Reach 1000Mm. The Focal Ratio Of The Newtonian Mirror Can Reach F / 4 To F / 8, Which Is Very Suitab For Observing Those Faint Extragalactic Galaxies And Nebulae.
