The key thing to keep in mind is you are trying to make you happy, not someone else. Winn said they equaled a Conquest HD, okay, but for me the Conquest HD pretty much equaled any I tried. But I dont pay a lot of attention to anything other than what I am looking at. Others seem to fixate on everything about the optic other than what they are seeing.

As far as I can understand, it is not possible to eliminate any optical aberration without making another worse, although much can be done to minimise these.
Since this means that a good handful of 'issues' are therefore always going to be present to some degree, it makes no sense to me to use special methods to reveal these issues unless any of them actually interfere with normal observing.
If normal observing can be done without being spoiled by any of these issues then I am a happy bunny :t:
Of course we can always discuss and argue about brightness, colour, FOV and perceived sharpness but my bins are used for observing not agonising.
