NASA APOD

Starlink Satellite Trails over Brazil

What are those streaks over the horizon? New Starlink satellites reflecting sunlight. SpaceX launched 60 Starlink communication satellites in May and 60 more in November. These satellites and thousands more are planned by communications companies in the next few years that may make streaks like these relatively common. Concern has been voiced by many in the astronomical community about how reflections from these satellites may affect future observations into space. In the pictured composite of 33 exposures, parallel streaks from Starlink satellites are visible over southern Brazil. Sunflowers dot the foreground, while a bright meteor was caught by chance on the upper right. Satellite reflections are not new -- the constellation of 66 first-generation Iridium satellites launched starting 20 years ago produced some flares so bright that they could be seen during the day. Most of these old Iridium satellites, however, have been de-orbited over the past few years. Infinite Loop: Create an APOD Station in your classroom or Science Center.

Bath Astronomers were exhibitors at Families Day this year and met up with several hundred budding scientists and their parents. Jenna managed to capture the spirit of the day in a few photos.

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.
