I use this scope primarily for birdwatching and very occasionally for looking at the moon, stars etc. The soft case supplied with the scope does not have the flexibility to keep it on while in use, which is surprising considering the scope was originally price around the £600 to £700 mark. I corrected this by cutting a flap in the case at the adjusting wheel, which now allows use with the case in place. To my eyes the optics are very sharp and colours excellent. Picking out fine detail in bird feathers is very easy indeed. That is until you go above 30 times magnification, then the light starts to cut down and overall the view gets a bit grainy. At 60 times magnification, it is very difficult to bring items into focus. It can be done, but a fine focus wheel would help. I recently bought a 22 times fixed magnification wide angle eyepiece for £30, from a popular auction site. This has made a significant difference, improving the already good definition and colour. I also own a Bushnell Spacemaster 60mm Scope, fitted with a fixed 22 times magnification wide angle eyepiece, which was also a vast improvement on the supplied zoom eyepiece. The Celestron is a brighter scope, offering more detail, as you would expect. But unless you are planning to be out in low light conditions, where the Celestron is in a different league to the Bushnell, the extra weight, size and cost in my opinion, isn't justified. Overall I am happy with the Celestron, especially now with the fixed eyepiece, but if you are going birding in normal light conditions I would opt for a 60mm or maybe an 80mm scope, as the Celestron's bulk stops me from choosing it first over the Bushnell. However, in low light, it really is excellent.
