Despite all the advertising hype you have to admit that there is some amazing gear out there. Looking back through old S&T mags makes one realise that we truly live in an era of wonder, particularly with the advent of the CCD. Without the CCD's the amateur community would not be able to produce pro level imagining, or at least, as easily.
Amateur astronomy is going ahead in leaps and bounds, so are the claims all that unrealistic? Not if you compare it with equipment from 20 years ago; or indeed, from only a few years ago. The quality and price of optics is far ahead now to what was available 20 years ago. Once upon a time we had to build our own telescopes. That is fine if you like actually building things but wasn't fine for those that wanted to partake but didn't have the skills to build there own.
We share the laboratory with professionals and now we can actually make serious contributions, if one desires to do so.
I am glad I am alive at this time in history! We are fortunate indeed!
Cheers Pete.
