  again  to  come   back   to   the  liveview  interface   and   frame  your   object.   With

liveview taking images in 10x10 binning mode, even an exposure of a few seconds easily

reveals most deepsky objects, making the framing process very easy.

STEP 7: check temperature stability

The cooling process should reach a stable set point temperature after 10-15 minutes

depending on the environment. The time needed to reach the selected temperature set

point may be shorter, but the algorithm needs some more time to calibrate in order to

maintain a temperature stable to less then 0.1°C

Push  

Done

  to   leave   the   cooling   app   when   temperature   is   reached:   leaving   the

application   doesn't   stop   the   cooling   process.   Next   time   you   open   the   Temperature

Monitor application it will display the current cooling process state, until you push the

Stop

 button, which will ramp down and switch off the cooling process.

STEP 8: set the exposure parameters and start photographing

Stat the 

Take Photos

 application.

Using the tabs named as the filters you set in the Setup application, you can define for 

each filter the exposure time, the number of exposures and the binning level. Remember 

to check the 

enable

 box in order to use the selected filter. 

Choose a photo sequence name. If you omit a path before the name, the photo
