Just purchased an Esprit 100 with AZ-EQ mount. I am in need of both 2x and (I think) 3x Barlows (or focal extenders). The OTA has a 2" eyepiece and comes with a 1.25" adapter. I have found available Explore Scientific 2" 2x Focal Extenders in both 2" and 1.25" sizes (2" is double the price.) At some point before long, I will be using the setup with my Nikon DSLR and/or a CCD camera, but I also hope to do observing with the rig. Can anyone tell me if the 2" is a far better purchase and if so, for what reason, given the described usage? Also, an ES 3x is available in both sizes and I would like the capability it provides, but I am worried the 3x might be beyond the abilities of my OTA (or so I've heard). Also, all TV Powermates are out of stock (and I believe they don't make a 3x), so I'm hoping the Explore Scientific will be of very high quality (I just bought several of their eyepieces). And is there any disadvantage of a focal extender v an actual Barlow? Thanks for any feedback.
