Mammatus Clouds over Nebraska

Jorn Olsen Photography

When do cloud bottoms appear like bubbles? Normally, cloud bottoms are flat. This is because moist warm air that rises and cools will condense into water droplets at a specific temperature, which usually corresponds to a very specific height. As water droplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near a thunderstorm. Resulting mammatus clouds can appear especially dramatic if sunlit from the side. The mammatus clouds pictured here were photographed over Hastings, Nebraska during 2004 June.

Buying a Telescope

So you're considering buying a telescope and the internet is awash with advice. So what can we add?

The key advice is to not buy immediately. Try to use a variety of telescopes in the field before you buy. You can do this by going to a public stargazing event or joining a local astronomical society and going on an observing night. All you need is a pair of 10x50 binoculars and your curiosity.

You can pick up a cheap pair of 10x50 binoculars from Millets for £15 to £25 - not great quality but they'll help you find objects in the sky.

Small, cheap telescopes (less than £150) tend to be very poor value for money as the view through them is limited, often coloured or distorted, and the view wobbly. The kicker is their resale value is low too.

If you have space to store it and can confortably lift 10kgs then we'd recommend the Skywatcher Skyliner 150P and preferably 200P. These are Newtonian reflecting telescopes on a Dobsonian mount costing between £199 and £275. These push me pull you telescopes are quick to set up and simple to use. You'll need to learn your way around the sky but then that's part of the fun.

If you wish to be more "astro tourist" and SatNav than learning your way around then a small to medium sized computerised telescope is a lighter but pricier option. The most compact versions are Maksutovs and Schmidt Cassegrains comprising both lenses and mirrors.
