The Celestron Radial Guider is a compact and well made device. It works very well with my 8" SCT. If you are new to astrophotography this guider will take a little time to get set up. However, if you plan to get involved in astrophotography, this is a "must have" device.I use the radial guider for deep sky imaging along with my SCT, Deep Sky Color CCD imager and my piggyback mounted 80mm APO refractor guide scope. My pictures are much improved and clearer. Ahthough, I am a rookie at astrophotography, I was able to get this device set up and used the first night out. They are many other similar guiders out there, but I cannot see how they could be any better than the Celestron Radial Guider. A lot of bang for your buck. Of course, this is typical of Celestron's products. If you are into or planning on doing astrophotography with your SCT, I highly recommend this product
Pros: Quality construction and easy to use.
Cons: None so far!...
Would recommend: Yes
