Hi all,
My eyepieces were selected to give me 4 types of magnification (Widefield, Low power, Medium power and High power).
Widefield Fields to view star clouds, nebulae to use as a finder for star hopping.
Low Power to view star clusters and stars in general
Medium Power for the moon, planets and some doubles.
High power double stars and moon craters and have a bit of fun!
The eyepieces were selected to put the 'scope through its magnification range.
Eyepieces:
Widefield - 'Scope @ 1100mm focal length.
AFoV = 69 degrees
TMB 40mm ............ mag = x28 FoV = 2.8 degrees
Pentax XW 30mm ... mag = x37 FoV = 1.9 degrees
Low Power - 'scope @ 1760mm focal length
AFoV = 69 degrees
TMB 40mm ............ mag = x44 FoV = 1.6 degrees
Pentax XW 30mm ... mag = x59 FoV = 1.4 degrees
Medium Power 'scope @ 1760mm focal length
AFoV = 55 degrees
Vixen LV 25mm ...... mag = x 70 FoV = 1.2 degrees (EOS 350 viewfinder!)
Vixen LV 15mm ...... mag = x117
Vixen LV 9mm ....... mag = x196
High Power 'scope @ 1760mm focal length
AFoV = 45 degrees
Vixen LV = 6mm ..... mag = x293
Vixen LV = 4mm ......mag = x440
Vixen LV 2.5mm ......mag = x704
