Fastar/Hyperstar secondary...

[truss]

Is the Fastar secondary worth fitting? I've been reading up on the Fastar system and I'm getting mixed impressions. Anyone on here have any experience with it on the C8 or similar?

There's a Fastar kit going for REAL cheap and I'm considering it.

This cheap thing will be Fun Star (https://www.revolutionimager.com/products/funstar-sct-adapter).. only mechanical adapter.
You have a lot about it on CN

Probably acceptable for small sensors.. but not very good in light polluted areas (f/2) and for larger sensors (including APS).

So, US$80 is not cheap... wait for ebay, they will be no more than AU$20.

I wonder if anyone with a funstar tried it with a field flattener used for refractors? or coma corrector for newts?
