Itekhnoloji yokugquma enezingqimba ezininzi kumphezulu opheleleyo icinezela ngokufanelekileyo iziporho kunye nokukhanya xa ijonga iinkwenkwezi ezikhanyayo ezifana neSirius. Ngonyango lwangaphakathi lokunyamalala, inika indawo yeenkwenkwezi zasentsimini "efana nenaliti" kwinkqubo ye-f/6.5.
Xa kuthelekiswa neKellner yakudala eyi-25mm evela kwezinye iimpawu, ububanzi bayo belensi enkulu kunye noyilo lwe-diaphragm oluguquliweyo luzisa umgangatho womfanekiso oqinileyo, kwaye indibaniselwano yekomityi yerabha kunye nokunciphisa amehlo eyi-24mm kuphucula kakhulu intuthuzelo yokujonga ixesha elide.
Ukulinganisa kweengcali kubonisa ukuba i-eyepiece idlula inqanaba elifanayo le-Kellner variant kulawulo olujikelezayo, ukulungiswa kwentsimi, njl. Ifanelekile ngokukodwa ekujongeni iithagethi zokukhulisa eziphakathi nezisezantsi ezifana ne-open clusters kunye ne-Orion Nebula, kwaye ibhokisi yokukhusela uthuli oluqinileyo iphucula ukuthembeka kokusetyenziswa ngaphandle.
