Hiya,I went out tonight for the 1st time with my guide cam starlight xpress and a celestron OAG,it's all connected laptop to cam,cam to scope but all I get is a lot of white noise and no stars at all,but now and again when looping I press any tabs up top like tools or mount and then cancel it,for a spilt second it goes ok all black with stars but just as quick all the white noise comes back.any tips pls pls pls (

That sounds to me like you are out of focus on the guide cam, on my setup the view in phd can be very noisy untill a star is on the chip, then suddenly the background goes dark and it shows a star (or usually lots of then).

Did you set up the OAG during the day and check the focus and alignment?

I use 1 sec exposures in PHD 2.2.1a with a slit guider ( similar to your OAG) on a C11 and Lodestar.....

Move the screen brightness slider (middle bottom) and see if that helps...

Ciro,

Hmmm

I assume you're using the Canon 700D for the primary imaging...does this show a focused image on a distant object?

If it focuses OK, then you need to adjust the position of the Lodestar (without moving the telescope focuser) until you can get a similar focused guide image. Use the shortest possible exposure.

Yeah I can get the canon focused fine,just got tolded that the lodestar uses a lot of power and I was only having it connected with my laptop using the laptop battery,should It be plugged into the mains

I just run the Lodestar from a powered USB hub.....

As you probably know, the lodestar is a very sensitive camera. It should give an image with minimum exposure times.
