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:
1) Attach a standard ‘M42’ SLR camera lens to the SXV-M7C, using a 27mm spacer
to achieve the correct focal distance. M42 thread spacers are available from most
photographic stores, or from Starlight Xpress dealers.
2) Create a ‘Pin hole’ lens by sticking a sheet of aluminium baking foil over the end
of the 1.25” adaptor and pricking its centre with a small pin.
