Recording your first image:
We now have the camera and computer set up to take pictures, but an optical
system is needed to project an image onto the CCD surface. You could use your
telescope, but this introduces additional complications, which are best avoided at
this early stage. There are two simple options, one of which is available to everyone
with a sheet of aluminium baking foil:
1)
Attach a standard ‘M42’ thread SLR camera lens to the camera, using the 26mm
spacer to achieve the correct focal distance.
Or
2)
Create a ‘Pin hole’ lens by sticking a sheet of aluminium baking foil over the end
of the adaptor and pricking its centre with a small pin.
