150mm F8 planetary scope (GSO mirror)

150mm F8 planetary scope (GSO mirror)
Have had great views of Saturn, moon & double stars with this high contrast scope. Interestingly, although 100% field of illumination is only 8mm & light fall off is steep outside this, I had a v. good view of the great nebula in Orion, lots of contrasty knots and detail (using orthoscopic & RKE eyepieces) despite observing from North Adelaide. .23mm-wire spider & 22.5mm diagonal produces about 2.8% obstruction of main mirror by area and faint diffraction spikes only on stars & planets brighter than 1st magnitude.
