At 1500mm f/l I dont think 6 deg fov Is achievable, r wanting if on the main scope or r u talking about using a finder scope?
You would need a 4" focuser & Siebert observatory style ep to get the wide views you're after
Even a 40mm swa 2" ep , 1500/40 = 37x, evn a 72 deg ep is only giving yo 2 degrees of view
