Larger Aperture 38MM OCAs 

Instructions 

 Use the sections below to set up your OCA. In the sections the numbers are the OCA threaded components that connect together. #1 would be the top of the OCA that connects to the binoviewer. The sections will reference pictures and videos that will give visual illustrations.

First ---Watch these orientation Videos:  (Video #1 and Video #2 )

Second ---Look at all the component numbers that make up these OCAs because they all include the same common components. These being Numbers #1,2,3,4,5 and 6. #6 is a second optical cell if a Multi mag OCA is purchased. #4 is the primary optical Cell all OCAs have. See
 Picture #16

(Instructions For refractors below)

Instructions

Cell #4 is the Default cell number if you get the Single magnification OCAs. If you get the Multi Mag OCAs there will be additional cells and they will have added numbers. The lowest power will always be labeled #4.

EX: If you get the 1x 1.5x and 2x MultiMag then 1x will be marked #4 the 1.5x will be #6 and the 2x will be #7

EX: If you get the 1.3x and 2.0x MultiMag then 1.3x will be marked #4 the 2x will be #6

Each part has a number and an arrow stamped on it. These arrows are important when learning how to set up your OCA for different telescopes. Once you become familiar with the way the OCA works you will likely not need to use these marks.

One more thing. The optic cells also have a number and arrow on them. It is important that the optics point in the right direction to do this you need to remember that the arrow always must point to the telescopes objective.

The above are basic configurations. There are alternate configurations depending on your equipment. After you have used this OCA you may have questions about specific uses.. Call or Email.

See the Videos below for more breakdown info.
They are for the Elite bino OCA but also in principle apply to All the 38mm CA OCAs

**The 1x OCA
is





**The 1x OCA is not specifically recommended for Newtonian type telescopes. The reason is the device would need to be made longer then the default arrangement is set up for. The length of the OCA is optimized for the 1.3x OCA and more powerful. The more powerful the OCA the shorter it can be hence you can remove some components. The 1x would need add another 10mm-20mm to the OCA to be close to par-focal on Newt type scopes. This might also create an incursion in the OTA of the telescope. Not a problem in low power viewing but some people don't like it':)
 
If you really want to use the 1x OCA with a dob/newt let me know. A customized OCA can be made. Let me know what binoviewer and telescopes specs we will be dealing with. 919-553-3980 or harrysiebert@nc.rr.com

If a video in the sections









If a video in the sections are refered to as "concept" videos this means that the video is included to give you an idea of the concept of what to do. Use the pictures referenced for exact details and components information of the setup. If the word "Concept" is not used, the video will apply to that exact setup.
