    Default Purchasing an eyepiece and a Barlow



    I am thinking buying a 6mm eyepiece and a Barlow for my Orion ed80 telescope. I want it look at planets or maybe deep sky. Is Celestron OMNI a good choice? I do not want it to be too expensive but I can see things well.

    The 6mm has a 50° field of view with about 4mm of eye relief. If you Barlow it to a 3mm you will be pushing your telescope to 63x mag per inch which you may not be able to use very often. It will work on the moon and planets but as a DSO eyepiece at 3mm your FOV will be .25° which is pretty small for that.
