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 SXVF-H36, using the 27mm
spacer/adaptor to achieve approximately the correct focal distance.
2)
Create a ‘Pin hole’ lens by sticking a sheet of aluminium baking foil over the end
of the lens adaptor and pricking its centre with a small pin.
If you use a normal lens, then stop it down to the smallest aperture number possible
(usually F22) as this will minimise focus problems and keep the light level reasonable
for daytime testing. The pin hole needs no such adjustments and will work
immediately, although somewhat fuzzily!
