Best camera for ZWO OAG?

maudette

Hi;

Did some search but was surprised not to find a subject on this...

I currently have the ZWO OAG that I'm trying to use with a 1800mm VC200L Vixen. I use the 120mm for the OAG camera but i have a real hard time to find a star to guide to. I have to use Max gain and 5 sec exposure to get anything and its really not good (ie. for M81).

I'm willing to get another camera with a better QE and Sensor size. the ASI174 has the bigger sensor so the FOV should be better but the OAD prism is so small. So is a ASI174 worth it?

The ASI290 seems to have a good QE and slightly bigger sensor size compared to ASI120.

I really want maximum FOV second a goof QE. Any suggestion for 2000mm range scope? (I would also like to use it on my RC 10" F8).

Thank you

Michel

Hi Michel,

Yes, the ASI174MM mini camera is a better camera compared to ASI120MM mini. It has the biggest sensor compared with ASI120 and ASI290, and it also has high QE. This camera is worth to use as a guide camera.

Have a nice day.
