Its a 6" Newtonian : 100 cm from primary to secondary and 152 cm from secondary to eyepiece... I have a good 25 mm eyepiece and an OK 23 mm that I use primarily. I also have a 4 mm & 10 mm that aren't very functional in my area ( 1 hour west of Philly).
I foresee a trip into lesser radiant areas for better viewing. .............. Thanks for the input. I think it is f5.
