My manual didnt state any AFoV.. maybe low cost eyepiece.
That mean if i use 4mm 50 degree eyepiece to view the moon the image will be closer than 4mm 82 degree eyepiece??

Hi Weixing,

Thank for the calculation. But how's it look like at 0.44 degree???
Mine 4 mm eyepiece didnt state any AFoV??? why??

could like to ask anyone.. what does it mean " 82 degree " ?? from this eyepiece "William Optics 4mm 1.25" UWAN eyepiece 82 degree"
