Talk by Roger Pickard, Variable Stars

27 NovHerschel Museum of Astronomy

Wednesday 27th Nov – Monthly meeting. This month we start at 7:00pm as the talk is preceded by our General Meeting and vote for the Committee. Talk starts at 7:30pm. Roger Pickard is visiting Bath Astronomers on Wednesday 27th November to talk to us about getting into variable star observing both visually and with a camera. This year Roger completed 20 years as the British Astronomical Association's Variable Star Section Director and has passed the baton on to a new director, Jeremy Shears. He remains as Assistant Director. Roger has a wealth of experience observing these variations in the night sky over 50 years and has published many articles along the way. Estimates of the changing brightness of stars can give clues to the nature of individual and binary star systems and uncover mysteries still without explanation. The talk will cover, in general, the type of star recorded by the BAA Variable Star Section and will include an outline as to what they are and how and why they change brightness. In addition, Roger will shown you how to find and estimate the brightness of a variable star. Bath Astronomers monthly meeting for all members and new comers to meet up, enjoy perhaps a new topic and a cup of tea and a biscuit. Held on the last Wednesday of every month at the Herschel Museum of Astronomy, 19 New King Street. The format is open and comprises an update for the month and a talk on an astronomy topic within the reach of amateurs. All Visitors welcome and there is a charge of £5 which helps cover the cost of the venue. Reduced to £2 for juniors, students or WHS/Bath Astronomers members. Registration is not required.

M16 and the Eagle Nebula

Martin Pugh

A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed portrait of the region was made with groundbased narrow and broadband image data. It includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. Extending from the ridge of bright emission at lower left is another dusty starforming column known as the Fairy of Eagle Nebula. M16 lies about 7,000 light-years away, an easy target for binoculars or small telescopes in a nebula rich part of the sky toward the split constellation Serpens Cauda (the tail of the snake).

Come along and chat with other amateur astronomers at the New Inn, Monmouth Place on Thursday 30th May at 7:30pm

This meetup occurs every other month and is a good opportunity to catch up with friends and new members.

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.
