I’ve started using the Antlia OAG with integrated filter drawer and had originally begun with my existing 290 mini guide camera. However on some dimmer targets I couldn’t acquire a suitable guide star. So I purchased the 220 with its larger sensor to give more fov. This appears to have worked and it is now good to go. Sensitivity is really good, with near IR capability. Excellent service as always from FLO!

I bought this ASI220MM from FLO in Januarry when down sizing my portable imaging rig. I use Kstars/Indi/Ekos software. I paired it with a Willams optics 50mm guide scope. It worked fine as a guide camera. No issues at all.

This combination gives 4"/pixel.
