No it is not a GSO scope. It is from Chinese manufacture called 'Hi optic' [link below]. I have had some dealings with these scopes a year or so back and basically they are best avoided.
The primary issuse was the mirror which is spherical and obviously gave very poor images. An F/4 scope has reasoanably severe coma to start with and they reqiure a well made parabolic mirror - like the one GSO does sell.
Collimation is also crucial with a 'normal' parabolic F/4.
One observer here in NZ exchanged the mirror with a GSO parabolic version with much better results. The aditional cost makes it prohibitive really.
The mount is a GSO Skyview 1 / EQ-3 'clone' which is also at the limit for this 8 inch.
Best to avoid.
