2"WO diagonal to 2" focuser, or RA motor.

[ketans]

Hallo Friends starry eyes,

I am going to buy the Celestron Omni XLT 102 refractor. It has got a 2" focuser, but 1.25" diagonal. Can you tell me whether the William Optic 2" dielectric diagonal will fit directly to the focuser by just removing the 1.25" adapter? Will I have to add some adapters for the 2"?

Important question is. With tight budget, I was choosing between WO 2" Diagonal and Dual axis CG-4 RA motor drive, as a first basic upgrade along with the scope. Did I make a good choice by choosing the 2"WO diagonal over the RA motor? What do you think?

Rest of the upgradations, I will be able to buy next time.

The telescope specifications are-

Fully Starbright XLT multicoated 102mm aperture 1000mm focal length f/9.8 achromatic optics; CG-4 German equatorial mount with setting circles, manual slow motion controls, and adjustable height steel leg tripod with combined spreader bar/accessory tray; 6 x 30mm straight-through finder; 2” rack and pinion focuser with 1.25” eyepiece adapter; 1.25” prism-type 90° star diagonal; 1.25” 25mm eyepiece (40x); dewcap; dust covers; TheSky Level 1 star-charting CD-ROM software.

see you soon, sincerely Ketan.

Hi Ketans,

Yep the WO focuser will fit straight in when you take the 1.25" adaptor out but yes, I'd get the RA motor first..

Hallo Gaz,

Thank you for telling.

My thoughts were, I would practice manual tracking for a month or two, then next budget when I buy other accessories like T-Ring, adapters and extra eyepieces and the RA motor etc, then it will be useful for photographing and accurate tracking.

Then basically for best viewing I thought to get that WO 2" Diagonal at least for now.

Ok, then Celestron RA dual axis motor for CG-4 mount is of the same(little less) cost that of the WO diagonal.

Is it a accurate one (for photographing in the future)? Vixen motor is double the cost.

see you, Ketan.
