Of course, this was not taken with typical mass-produced (Chinese-made) optics mounted in a plastic tube. I haven't seen the specifications of his set-up, but the cost mentioned in the newspaper article (5,000 GBP or a little under 10,000 USD) probably means lambda 6 or better glass (that was tested, not "claimed", to be lambda 6, as some disreputable distributors and manufacturers often do).
Aside: By using lambda in this way, I mean the measure of the wavefront integrity of the light as passes through the telescope. The closer it is to perfect the higher the number is. Lamdas of 1 to 3 are what you expect from mass-produced consumer-grade scopes. Lamda 6 from serious amatuer scopes. Lambda 12 is military grade. And lambda 20 is simply amazing to look through. High lambda telescope optics usually come from Russia, although I have also seen high-quality binocular assemblies from Japan. My comments are based on my personal experience and if you have a different opinion, please speak up as I am always interested in learning more about high-end optics and astronomy.Taken all together, good quality glass, good quality digital camera, probably some image enhancement (frame averaging), decent weather, perserverence, and a keen interest in astronomy combine to give us this eye-catching image. My congratulations go out to Mr. Legault.
