[mark skelton]

Hi I have Starlight xpress H674 mono connected to my s.w. refractor  the trouble I  go too take a 10 sec exposure  I get  a black screen looks like the settings are a bit out. Does anyone who's using nina  know how to get the stars shown?

Can you see Jupiter? Brightest object in the sky at the moment.

Think there maybe an auto stretch button on the top bar of the image tab towards right hand side, this is for previewing your images and doesn't save/alter your saved image, I always had that turned on. Maybe it will help

If you can't see anything in a 10s exposure then it was probably a focus issue. If you didn't manage to get it resolved last night, try focusing on a distant object in the day.

What scope are you using? Whatever the focal length is, try measuring from the optics down the tube to where your sensor is. It should be roughly the same as the focal length.

Like others say, focus on a far way lamp post of chimney etc during the day. That'll get you close enough. Otherwise I often find that a guide scope or red dot finder is helpful when setting up a brand new scope.

It's a skywatcher 80 ed pro with a focal length of 600mm and a focal reducer bringing the focal length to 510mm

Have you power going to the camera? You get black if you haven't.

Simple experiment I resort to occasionally... shine alight down the scope. If its all hooked up OK you  should get something!!

I get a msg on nina saying camera connected and when I go to the camera tab the camera profile (chip size/ pixel size) are shown. As I found out with apt if no power to cam the software cannot connect.

Silly question perhaps but how are you taking an image? Theres a live view function which is a bit flakey, and also a snap shot button which you can set to loop.

Not a silly question, but what the difference between the two. I assume that the snap shot is the one used for plate solving.

Live View is supposed to be like the live view on a DSLR but it's not great in NINA. You better off to set an exposure time, 10s for example, and make sure the loop tab is selected.

Yes my understanding is that liveview is effectively video standard.

So I wonder what method you are using? Yo could set a sequence, but thats the only other method I know.

next time I get chance to to connect to the equipment I'll give the loop  selected

It's turned on so is the star detection next to it

yes I have power to the cam ( software can't connect if no power to camera).

[mark skelton]

Just to update I took the S.X. H674 camera off and put my spare camera (atik titan) on turned the looping of. This time I got an image on the screen.(looks like it could be the h674 camera at fault}.

Well that's progress I suppose. Is it something to do with the driver? 

Do you need to download a driver maybe? I think for some cameras which the imaging software doesn't recognise you need to use the ASCOM driver option.

got the latest driver for the camera and my laptop does meet the requirement
