the 60 degree 5 element Plossl 26mm EP- reticle? new
      #2688856 - 10/09/08 11:04 AM

Hi folks. I am learning now about reticle EP's. I am going through the autostar menu in setup and trying to set the intensity for reticle. I can't seem to get the menu to work. Is it possibly because this EP is NOT a reticle EP? Any suggestions are greatly appreciated...

Your respectfully
Chris

Hi all. Hope all is well. Please let me clarify something in here please.. I ASSUMED that reticle meant that an eye piece wal illuminated, but as I do more research I believe, once agian I am wrong! I lovce being wrong as it helps me learn! So I guess the real question was is this eyepiece an illuminated one. The reason I ask that is because when I insert the eyepiece I notice there is a thin "copper band" that it inserts to. My brain assumed this was an ' electrical contact point". Silly me or not silly me???

Heya Chris,

Learning is good!

The 26mm EP you got with your scope is not a reticle. Reticle EPs come in a few varieties but they always have some type of viewable marks in the field of view when you look through them. For example, your finder scope -could- be seen as a type of reticle since it has a cross hair.

Now, many reticle EPs have an etching in the glass that allows a light to illuminate it for night use. These are called, you guessed it, Illuminated Reticles. They typically come in two varieties, wired and wireless. The wired type plugs into your control panel and the intensity of the light can be controlled by the HBx (handbox). The wireless type has a battery powered LED light (red of course) that usually screws into the side of the EP and is adjusted via a little knob.

There are some other kinds of illuminated reticles as well such as CCD framers and astrometry EPs.

So, you ask, why would I need an illuminated reticle? Well, in sighting scopes and finders it makes lining the object up much easier in the dark. As for actual EPs, these are most commonly used to help achieve very accurate alignments. Many illuminated reticles you will find out there are either 9mm or 12mm. These give higher magnification so, again, you can get those really good alignments. In addition, folks use illuminated reticles to help them during polar drift alinment... but that is a whole other story.

Cheers!

Hi Chris....this is what a Reticle eyepiece look like.
The view of the cross - hairs is below left and glows red as you increase the light intensity.

Cheers

aaah ok gotcha. so are the brass rings inside the scope EP casing for supplying power to a reticle?

No...that is to clamp the eyepiece. A battery is located in the shiny part at rt angles to the eyepiece. The tip is rotated to switch on and power up the reticle from low to high intensity.

Meade makes a reticle eyepiece with a cable that is plugged into the scope below the microfocuser plug. This is then controlled by Autostar.

Cheers.
