Imaging with a modified DSLR Camera


Recommended Posts

Hi all, noobie question.

i just purchased a modified DSLR camera to ( Canon 450D) start Astro imaging..

My question is, to those in the know, do you get a preview on the LCD, as all I get is a pinkish hue.

 If that’s normal, how do I know I have what I’m aiming for.


thanks in advance.

some good info on setup here :



Did you say that that's not right?


These are the settings I use.



1.   Exposure level increments - doesn't matter

2.   Flash sync - doesn't matter

3.   Long exposure noise reduction – off

4.   High ISO speed noise reduction – off

5.   Auto lighting optimiser – disable

6.   AF assist beam firing – off

7.   AF during live view shooting – off

8.   Mirror lock up – disable

9.   shutter/AE lock button - AF/AE lock

10.   SET button when shooting - LCD monitor on off

11.     LCD display when power on – Display

12.     Add original decision data - off

·      Set mode to 'M' and exposure length to 'BULB'

·    ISO is  800


·      Menu 1:Quality RAW (when shooting RAW things like exposure compensation, white balance etc. have no effect whatever)

·      Red eye off

·      Beep off

·      Shoot w/o card - personal preference

·      Review time  -- your choice, I go for 4 sec

·      Menu 2 - none of these matter, but don't set just delete data, you use flats for this.

does not display anything that's in front of the camera

To see what's in front of the camera in real time -like on your 'phone- you must set live view. On a 450, that's the video camera icon.

To see anything recognisable which is in front of the camera, you must also fit and focus a lens. Or telescope.

Fit the correct adapter/extension tube, then focus on a distant terrestrial object by looking through the viewfinder. That should get you close enough focus to record stars in a few seconds or so. You may even be able to see bright stars on the camera's LCD but much easier using an app on your 'phone/computer. Fine tune the focus on a brightish star.
