Hi all I am having an issue with ekos plate solving. I am using a skywatcher 50mm finder with an sv305 connected. Although a focal length is not easy to find I have found 180mm quoted by others here so I am using that. 

Aperture = 50mm
Focal length = 180
Cad info 
Sensor 1920x1080
Pixel size 2.9um x2.9um

Ekos  calculates 106.3' x 59.8' 

Astronomy.tools106.2' x 60'

Pretty close, right?

However I can't solve, I downloaded ALL Index files as I have plenty of storage and with say 10 clear stars in a capture it fails to solve. Please can anyone advise? is anyone else using this combination of finder and ccd?

Thanks in advance
