Hi all,

Another noob question... I am weighing up pros and cons for my first guide cam. All 3 have come recommended to me by different people. As I understand, I have written some pros and cons for each. Please help me make an informed decision by adding info or correcting where I am wrong. Am I going down the wrong track when saying that a "pro" is "main cam planetary imaging"...? Thanks for your help!

Starlight Xpress CoStar (used)
Pros: larger pixels & monochrome thus much more sensitivity, cheaper
Cons: second-hand, cannot be used as main camera for planetary as I don't have colour filters, USB2.0 - old technology & not "future-proof"??

ZWO120
Pros: monochrome, thus higher sensitivity
Cons: monochrome, thus cannot currently use as main planetary camera as I don't have colour filters.

ZWO120 MC-S
Pros: Can also be used for planetary imaging at decent frame rate (USB 3.0) in colour.
Cons: Colour = less sensitivity for guiding
