Surface of dust...

This was one of the funny incidents which happened few months back in the astronomy lab .(where I teach)
The labs I have to teach are always in the night(8PM-11PM).So as I was setting up the telescope for the day's observations, the students were just overwhelmed by the feeling of handling the telescope.There were nervous gossips ,biographical instances which were passed along,a laugh ,a complaint ...chaos..simple chaos..
The beautiful solitude under the stars have turned into a discordant noise.I was losing my patience,the nerves on my forehead were throbbing with irritation and I was not able to concentrate on setting up the focus for observing the peaks on the moon.I saw a cracked surface and sighed a heavy sense of relief.The students started looking at the object with constant suprise and awe.There was this boy who kept a intriguing look and told me that what I have focussed on is not the moon.It may be a crack at the eye piece.I got angry at my fault and at the same time I laughed at my foolishness.

What is an eye piece?
An eyepiece brings all the light rays gathered by the telescope into sharp focus. The eyepiece determines the magnification of the image as well as its brightness and contrast
There are various sizes which are used..25mm,12.5mm,40mm,7mm..

It happens so many times in our life.. due to the confusion and suffering that life offers we see,everything through a sense of negative ideaology.We feel there is no hope in the world.The world wants us to be punished and we burden ourselves with guilt.Only if we could look through with the eyes of hope and self belief we see the beautiful dreams ,the various sparks of divinity we are blessed with.

ha ha ha that reminds me of a Tintin comic "Explorers on the moon" where this guy is looking through a powerful telescope and is scared when he sees a gigantic creature in outer space... and it turns out to be a spider on the surface!!


Eyes work using a page fault mechanism. They’re so good at it that you don’t even notice.

You can only see at a high-resolution in a fairly small area, and even that has a big fat blind spot right exactly in the middle, but you still walk around thinking you have a ultra-high resolution panoramic view of everything. Why? Because your eyes move really fast, and, under ordinary circumstances, they are happy to jump instantly to wherever you need them to jump to. And your mind provides this really complete abstraction, providing you with the illusion of complete vision when all you really have is a very small area of high res vision, a large area of extremely low-res vision, and the ability to page-fault-in anything you want to see—so quickly that you walk around all day thinking you have the whole picture projected internally in a little theatre in your brain.

This is really, really useful, and lots of other things work this way, too. Your ears are good at tuning in important parts of conversations.
