does it work with larger chips ,like infinity?

 infinity's size blocks incoming light? i see that it is attached in the secondary mirror,like hyperstar..

seems quite interesting for this amount of money...

There are a couple of other threads in this forum on the FunStar and  the FreeStar (which uses a Celestron VisualBack instead of the FunStar adapter; they call it the FreeStar presumably because everyone already has the VisualBack that comes with the telescope). One issue is the degree of residual spherical aberration which is very apparent with the brightest stars - they appear very large across the whole field. Here is a link to one thread that shows the post where Don Rudny compares the Hyperstar view with a FreeStar view on the same telescope. You will see what I mean...
