Recently, I have experienced a frustrating situation, which almost all binocular owners face, the collimation problem. And once the binoculars are out of collimation, they give stupid double images which cause immediate headache while observing.
I picked my binoculars up from Karachi. Brother Abbas from Karachi Astronomers Society had fixed it after it was damaged.
Travelling back to Hyderabad, I noticed that the sky was so dark and clear since it was miles away from city lights. Asked father to stop the car so I could test the bino. As soon as I saw through it, I immediately realized that the binoculars had went out of collimation once again due to Super Bumps on Super Highway.
This turned me off totally for the rest of journey. As soon as I reached back home, I hit the internet in search of collimation guides. Found a few but I was so tired that I thought to give it a try next day.
Next day I went up the roof in daylight and tested the binoculars at a far away person sitting on the roof of a 6 floor building. He was appearing double. Then I started tampering with the Porro-Prism screws of the binoculars, tested it again and again but couldn’t get the satisfaction, so left the work until the night.
At night, I again picked up the screw driver and started turning the screws around. After about 15 minutes of frustrating work, the Double Jupiter finally merged into one image and gave a crisp view. This was the first ever time I saw Jupiter’s Galilean moons.
Collimating a binocular is a super easy but a frustrating technique, as you have to test the binoculars with every drive you give to the screws.
Clear Skies.
