the 8" GSO is 200mm x 1200mm making it F6. if you take care you will rarely have to clean the mirrors. I have had mine for about 1.8 years and it still hasnt been properly cleaned. I did blow off some hairs once... mirror cleaning isnt hard but needs to be done properly. if you searchthe forum there are threads on cleaning mirrors
have fun!
