Ant Posted April 23, 2014 Share Posted April 23, 2014 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).Cheers Ant Link to comment Share on other sites More sharing options...
Merlin66 Posted April 23, 2014 Share Posted April 23, 2014 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...

Merlin66 Posted May 16, 2014 Share Posted May 16, 2014 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.

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 mainsSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Merlin66 Posted May 16, 2014 Share Posted May 16, 2014 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. Link to comment Share on other sites More sharing options...
