Bojan,

Then you need to read further and deeper - its very clearly explained.

I think your assumption that your lens is the same as their lenses may be incorrect.
Or maybe it isnt but you havent been aware of the technology in your lens - Im not sure exactly which lens design you have.
But is is also about the difference between the limiting magnitude resolving capacity of a refractor and reflector.

It has much to do with the almost complete loss of internal reflection due to the technology and process used to create the lens surface.

The concept of using multiple lenses is as you say, used to increase light and decrease integration times, its also about simultaneously capturing all bands (filters) concurrently.
So that is no different to normal - but the significant ability of their optics to see 4 orders of magnitude further than the previously accepted limit is what sets them apart.
Also by having multiple systems, they are in effect getting the benefit of all the tiny offsets in positions thereby reducing data collection noise in the one sitting as opposed to multiple sets of integration times.
Inbuilt static drizzling and dithering if you wish !

You might be interested to start reading some of their many papers (approaching 300) to see that their claims are all well documented, measured and proved.
Its all peer reviewed.

Once you have read a few - you will appreciate just what a paradigm shift their approach is and how it could conceivably revolutionise this entire field of astronomical imaging.
Their tiny little system can see what all the worlds biggest observatories cannot see for a mere fraction of the cost, compexity and logistics !
If they had enough funding and Im guessing that will come - they could duplicate their system 50 times over in the space of weeks and months rather than decades and billions$

In fact its the perfect example of a major scientific advance that well funded amateurs could jump on in the space of months and contribute to the science !
This is such a brilliant opportunity for amateur funded discovery.
They simply cannot look at the entire sky in the space of months or years - amateurs can beat then to it with "modest" 10 lens systems !


Cheers
