Cant see stars through Bresser Messier 127/1900 Maksutov with camera

Hi all, 

So as the title says, I cant see any stars in sharpcap through my T7C (ZWO ASI120M sensor) hooked up to my Bresser Messier 127/1900 Maskutov Cassegrain F/15. I've used a lens to get the star roughly in the centre and when I put the camera in, I can turn focus both ways, I've changed exposure time and gain and just don't see anything other than Jupiter. Has anyone any experience with this or am I missing something really obvious? and can anyone offer any advice?

Thanks Rich

Ok so if I disconnect the t7c and plug in my ZWO ASI120mm mini I get a visual. Then unplug that and put the t7c in again and I get an image. I really don't know why its happening? Sharpcap recognises the t7c as a zwo 120mc. Strange

Have you got he latest drivers?

Yeah, the zwo works first time everytime but the t7c doesnt until I've already had the zwo plugged in. It's like it needs the zwo to start a script or something
