Dark skies of Pakistan is one of the most blessed thing for Amateur Astronomers. Sindh and Balochistan has been blessed with dark skies just by moving out 100 kms from the city. Karachi does have light pollution but a few Kms (100) away there are no large cities and so no light pollution.

In the following maps, you can see the rich dark areas of Pakistan and the light pollution shown with color highlighting.

 

Light pollution is most amateur astronomers’ worst enemy. There are two aspects to the problem: glare and skyglow.

Glare refers to light shining directly in your face — typically streetlights or your neighbor’s “security” lights. Severe glare can make stargazing impossible, but most people can escape it by finding a shadowed corner, erecting screens to block the light, or traveling to a park nearby.

Skyglow, the diffuse glow that fills the sky itself, is harder to escape. A major city’s glow is a serious problem anywhere within 50 miles (80 km) of the center, and it’s visible for at least 150 miles.

It’s extremely helpful to know how strong the skyglow is in your area to calibrate your expectations. For instance, the huge but very diffuse galaxy Messier 33 is quite easy to see through hand-held binoculars in a pristine sky, but it’s extremely hard to make out even with a large telescope from a typical suburb, where the skyglow is many times more intense than the galaxy’s light.
