You can use solar film to make your own solar filter that gets placed on your telescope to protect your eyes. Inside this refractor, there is an internal etalon with tune adjustment that allows for a maximum of <0.75 Angstrom bandpass.. Regrettably, the Sun decided not to provide any sunspots for this inaugural photo. If so, I assume a "monocular" would be too low a power for one of these, correct? The poor contrast due to the light coming in from the sides made it more difficult to pick out the sunspots. It might have worked if he had used a finer grit sand and had a more controlled method for spraying. The rib and the dowel pin to help align and hold the scope into the correct position. Tape or hot glue them together. I use a 1/4" x 20 bolt attached to a wooden knob from beneath to lock down the scope. Expanding the 1.25" diameter image to the 4" diameter image dimmed the overall image by a factor of about 9 (based on the ratio of the square inches of the image). To locate the CG, I assembled the unit, including the mirror and telescope and sat it (in the same orientation as shown above) on a short length of dowel rod. If you are not confident in your ability to build a solar filter that . Your browser or your browser's settings are not supported. I don't think there has been a decent sunspot to look at in months:-(. Building my telescope, watching it swivel so smoothly, seeing the stars, I basked in the reflected glory of that ingenuity. Remember to allow annotations and view in HD. Then I tried a different tack. Cut out most of the center of these two pieces so you have two cardboard rings.
