Cne can't stucy astror:cmlr f'or"long bef'ore coning across the term "fie1dof vie\,u"',,,,vhich is sirnpl-y e measure of'the angle shov'm by an optical- systeii:,v,;hether i-l :.s a telescopen a. pair cf'binoculavs,, oy" an eyepiece" There aretiffo types of'fiel-d of views true fielcl and apparent fieki" The fortnerapplibi to c,omplete instr"uments (telescopes, binoculars, and finderscopes ) ,,

Apparent field ref'ey"s to the angle th.e eye "percei-ves" when it looksin.*,,) an eyel:iece" llhis can be thoughi of'as a. "cone of visibility", wiihthe apex a"L the observer's eye. Typical F,ellner eyepieees have an apparentfiei,J- of' 40 C.eg or so, 'Iele V-ure Plbssls have 50 deg, '/iicle Fielris have 5J deg,ancr Na.glers ha.ve 82 d.eg" f he rel a.tionship between true f ield and apparentfield is a simple cne t

True FieJ.d. r Apparent F5-eld,,/i"agnification.

For example, if a i3mrrr ltragler is used in a C8 (f'ocal )-ength 2000mm),-uhe rnagnification is 20A0/i3, or 1,J4x, and the true field is BZ deA/i54,or A,5,3 deg, When'the eye looks into a Nagler eyepiece, it always sees an32 rieg cone of visibilitir (neariy a right angle! ), but the actual angle ofsky seen ( the true field ) clepends on the focal length of the tel-escope used,because this determines the magni-f ication, (tf you hold this bulletin 5"from your €,ye , the short side of' lhe page represents approximately' the ap-paren"b field of' view of' a Nagler" )

What does all this meari to ttre cbserver? Tn general, the wider theappar.ent field of view an eyepieee delivers, the inore pleasing ihe vielv"Fields cf'view smaller than about j0 degrees tend to nake it seefl. as thoughone is iooking through a tunirel " l{ith th.e }ilagl-ers, cn the other hand, thetelesccpe seems to vanish, almost as if' one iS observing; through a large

,,r,indcw into spaee" You acti"rally have to looic around inside the eyepiecetc eLea::1y see the ed"ge of the field" Again, this relates to the fact thatthe e),e hls a 5A deg -1ear field cf view" 0uitside that cone, objects areperceived, but t'iot necessarily resolved.

For this reason, it rnay be ad"vantageous to use an eyepiece with asmaller apparent field wher:. sweeping for objects in the sky" 0f course,to rna.intain ti:e same true fieid, this will require a lower power eyepiece'in a CB, a" 21mm Pjossl will deliver a 0"53 deg fieid, but at only 95x, af;; opicosed to L54x for the lJnm Nagler, which-has the same true field.
