Figure 1: The solar filter is attached to the front of the lens.
2.3 Procedure if the solar filter does not fit exactly onto the tube.
For models that are attached over the outer wall of the tube: reduce the inner diameter of the filter
by inserting an additional strip (e.g. a foam rubber strip) to the inside of the frame. If you have any
difficulties with the accuracy of the fit, please contact one of our expert advisers.
2.4 Note: if you chose a filter that is too small, it will not cover the telescope's aperture and will
leave a gap. In this case, do not use the filter.
2.5 If you have chosen a foil filter, you may see ripples on the surface. This is normal and does not
affect the quality of the image.
3. Observation with a solar filter and telescope
3.1 Check once again that the solar filter is securely attached to the telescope lens.
3.2 Remove your finderscope.
3.3 Point your telescope at the Sun (without the finderscope) and insert an eyepiece with a short
focal length.
3.4 Look at the shadow cast by your telescope, and move the tube in both axes until the shadow is
small and circular. Now look through the eyepiece and centre the Sun that should now be visible in
or near to the edge of the eyepiece. If you have difficulty finding the Sun, we offer special solar
finders in our product range.
