MARS
MarscomesneartotheEarthevery26months.ObservingMarsisquitedifficult.Theuseofa
telescopeswithan aperture diameter of 100 mm ormoreandwith 100 times magnification
allowsobservationofthePolarCap.
MULTIPLE STARS
Severalstarsappearindividuallyinfrontofthenakedeye,butwithtelescopicobservation,are
comprised of two, three or more stars. Double stars are comprised of two components and
triplestarsarecomprisedofthreestars.Theuseofaquitelowmagnification,around40times,
issuitable.
NEBULAS AND STAR CLUSTERS
The large nebula in the Sword of Orion and the large spiral nebula in Andromeda can be
seenwiththenakedeye.Ifyouobservenebulasandstarclusters,itisrecommendedtousea
telescopewiththelargestpossibleapertureatthesmallestmagnification.
THE SUN
Theuseofatelescopeswitha40mmapertureisadequateforobservingsolarspots,however
thecontinuedobservationofthesunrequirestheuseofarefractorwitha60mmaperture.In
thiscase,theuseofaround60timesmagnificationisrecommended,inordertoseetheentire
