I'm trying to understand a bit better about what planetary cam to purchase down the line.
As I see it the ZWO cameras appear to be a popular choice at the moment both in performance and price in a similar way the Imaging source cams were a year or two back but they seem to be talked about as being a bit outdated now, although still produce great images.

What are the other good options and why?
I'm not sure I totally understand the sensor/pixel/f-ratio side of things either. For example would a different camera be better suited to two different model scopzs like a C11 over a C9.25 or would the same camera be interchangeable?
I ask this because it will be one of these scopes I will be getting.

Certainly the ZWO cameras are affordable but I'm open to spending more if there is a considerable advantage for a different make. I have seen that the Lumeneras appear to be good but truth be told that's probably just the wrong side of my budget.
As a guide I would probably say my max budget would be 500 euro so around 750 AUD.
