Hi
Have been compiling a list of marketing claims and trying to interpret what they might possibly mean - quite often significant negatives are spun and put forward as desirable features. Just a bit of fun and not intended to knock anyone in particular - they all do it. A lot of license has been taken with the wording, but I am sure you will have seen some similar claims :lol:
Regards Ray
1. “the mount has a 40,000 object database” – but you will only be able to see about 150 of them, since the scope we fitted is too small to detect the rest.
2. “the scope produces pinpoint stars on a black velvet background” - because there is not enough aperture for the skyglow to be visible
3. “the mount has little backlash” – we used to say it had none, but people noticed.
4. “the camera cools down to 55C below ambient” – which is only necessary because the chip is as noisy as all heck.
5. “the camera has built in RBI flooding” - which is a fudge that is only required to cover up an annoying fault in this particular type of chip.
6. “the Aluminium adjustment knobs have been replaced with smoother plastic ones” - that are cheaper to make.
7. “guaranteed diffraction limited” – we are fairly confident that some of them will work OK and not many of our customers will know the difference anyway.
8. “5 year warranty on the mount” – and to get it repaired you only have to ship it to and from the factory in Guatemala at your expense.
9. “USB3 for high speed download” – which you will never achieve, since USB3 is an aspirational standard in which nothing ever goes as fast as it should.
10. “superlative fit and finish” - which makes no difference to the performance, but means that you will pay us an extra grand for the paint. Red anodising is really valuable and might even be worth more than the right paint.
11. “comes with an ultra-wide-angle eyepiece” – which allows you to finally see the coma in all its glory.
12. “uses lanthanum/Fluorite/FPL53 glass” – yeah, we know that only 0.01% of our users really understand lens design theory (ie know if this is at all significant), but it sure makes the scopes/eyepieces easier to sell and gives the owners an inexhaustible talking point.
13. “The camera has a tilt adjustable faceplate” – because we haven’t figured out how to manufacture it so that the chip is guaranteed to be parallel to the faceplate.
14. “The camera is Argon filled” – well we blew a bit into it at one stage. Who knows, there might still be some in there - how is anyone going to prove that there isn't?
15. “Strehl ratio of 0.977” – which we got by hand-optimising the best unit we could find, mounting it to minimise any mechanical stresses in a thermally stable environment and testing it on-axis at the single (best) test wavelength. The analysis software was set to disregard residual astigmatism and anything else we didn't like.
