    • Dispense an arbitrary amount of alcohol into a bowl.

    • Take a pipette and submerge its narrow end into the alcohol, then squeeze and release the bulb end with your fingers to extract alcohol.

    • Firmly squeeze and release the bulb end so the pipette fills to the 1 milliliter mark.

    • Transfer and dispense the pipette's alcohol into a separate bowl.

    • Extract 24 milliliters of alcohol into a separate bowl.

    • Pour an arbitrary amount of distilled water into a bowl.

    • Extract 6 milliliters of distilled water and transfer them into the same bowl with the 24 milliliters of alcohol.

    • Stir the alcohol-distilled water solution with the pipette.

    • Transfer the solution from the bowl to the spray bottle via pipette.

    • You could carefully pour the solution straight into the spray bottle.

    • Screw on the spray bottle cap.

    • Locate the back of your telescope and notice the 3 pairs of screws with one screw sticking further out than the other in each pair.

    • Remove the three 19.1 mm lower resting screws from your telescope using a Phillips #1 screwdriver.

    • While unfastening the 3rd screw, palm the back panel of your telescope so it doesn't fall off unexpectedly.

    • Carefully pull back the loose panel exposing the primary mirror and set it aside.

    • Lay the back panel flat on a table with the mirror facing upwards and grab a camel hair brush.

    • To remove dust particles, lightly brush the mirror's surface starting in the center and pulling out towards the edge of the mirror.

    • Perform center to edge strokes 360 degrees around the mirror.

    • To remove tougher build up, take the spray solution and disperse 4-5 sprays onto a tissue paper.

    • Applying minimal pressure, mimic the same strokes as the brush by pulling the moist side of the tissue from the center to the edge of the mirror.

    • Perform these strokes 360 degrees around the mirror.

    • If build up still remains, repeat the motions above with more pressure but just enough to remove the build up.

    • Remove any remaining dust particles that accumulated since the tissue by using the brush to stroke the mirror as before.

结论

To reassemble your device, follow instruction 4 in reverse order. Line up and screw all the screws into their screw holes so the bottoms of the screw heads lay flush with the back panel of your telescope.

@ethan_powell awesome guide! Just purchased a telescope to get ready for retirement :-) Quick question. I am with the understanding to stay away from 70% isopropyl alcohol because of it contains 30% of impurities, which could lead to streaks. I was told to use at least 90% or higher, and to dilute isopropyl alcohol over 96% with distilled water, to prevent early evaporation. What is your thought on this?
