Celestron 44110 - mounting measuring reticle in eyepiece

Postby ccp3766 on Mon Jul 14, 2008 10:55 am

Before I buy one I'm trying to see if I can add a measuring eyepiece reticle to one of its 10x eyepieces. When I see things I want to know how big they are. Celestron said the scope takes a 19-mm diameter reticle. But (probably another) technician there gave no specific answer to a later question about any tools, spacers or retaining rings that might be needed - just warned that the guarantee might be voided. I had thought that it would be easy to put a reticle into an eyepiece. Has anyone ever done that? Some websites sell reticles to order to mount into microscope eyepieces. They're of various diameters, about one or two millimeters thick and have all types of scales on them, from which to choose; for example, one centimeter divided into 100 graduations. They can even decenter the scales. Thanks.

Hi

Can't offer you an adapter or eyepiece desinged for your scope - anything you do is probably going to require some fabrication on your part. Celestron makes some very useful microscopes for the money, but their forte is not microscope accessories or service.

It is true that any modification you make to any part of the scope will probably void the warranty, so proceed with caution. If it was my scope, I would measure the eyepiece tube diameter, then try to buy an eyepiece with a reticle in it.

Celestron 44110 measuring reticle

Hi
Can you unscrew the top eye lens? If so, you may find a field diaphragm about halfway down in which case you would be able to drop a reticle onto this ,provided the reticle is of the correct diameter of course
Is the eyepiece a widefield one ? These lenses don't have a field diaphragm so you would not be able to do this.
