Nu ai deloc oculare?

gasesti manualul la http://www.celestron.com/c3/images/files/d..._21039.pdf

care spune :
Eyepieces – An assortment of 1¼” eyepieces are available to give you a wide range of
magnifications.
• OMNI Plössl - Plössl eyepieces have a 4-element lens designed for low-to-high power observing.
The Plössls offer razor sharp views across the entire field, even at the edges! In the 1-1/4" barrel
diameter, they are available in the following focal lengths: 4mm, 6mm, 9mm, 12.5mm, 15mm,
20mm, 25mm, 32mm and 40mm.
• Ultima – Ultima is not really a design, but a trade name for our 5-element, wide field
eyepieces. In the 1-1/4” barrel diameter, they are available in the following focal lengths:
5mm, 7.5mm, 10mm, 12.5mm, 18mm, 24mm, 30mm, 35mm, and 42mm. These eyepieces
are all parfocal. The 35mm Ultima gives the widest possible field of view with a 1-1/4”
diagonal.

la un telescop cu diametru de 50mm s-ar putea sa ai nevoie de oculare pe 1",nu pe 1,25".
nu sunt sigur dar la unele lunete am observat asta.

strenchen de data asta are dreptate, desi vorbim de diametrul de 0.96" nu 1" (nu este idiferent, daca va cauta oculare de 1" nu va gasi).

Daca ma uit la manualul postat de Incepator si ai acest telescop se pare ca chiar vine cu oculare de 0.96" din dotare. Insa tot in acel document spune:

"Diagonal, Hybrid Mirror 90° (.96 to 1¼") #94106 - The economy Hybrid Mirror Diagonal (90°) provides a cost
effective way to upgrade telescopes supplied with .96" eyepieces, to higher quality 1¼" eyepieces."

Probabil ca ar fi indicat sa cumperi diagonala indicata si sa folosesti oculare de 1.25" ...
