Welcome to this AstroCamp podcast extra episode to tell you what you can expect from the weekend's festivities and listen to on the way to Cwmdu:

The Discussion: An introduction to star parties and enjoying practical astronomy under pristine dark skies away from the city.

As the podcast crew run the AstroCamp star party, which many listeners attend, in the Brecon Beacon's international dark sky reserve twice a year, we take you through the events, tutorials and workshops we run to help you hone your stargazing skills and win astronomy prizes from the Tring Astronomy Centre. As the focus of this AstroCamp is the Transit of Mercury, we will also have two talks on the celestial event, from the University of Kent's Dr Rebekah Higgitt and solar astronomer Eric Emms.

The Sky guides: In readiness for 3 nights of stargazing in the Welsh valleys, Ralph, Paul and John choose objects to look out for this time of year. If you're not coming to AstroCamp, these are still great night sky treats to try and locate wherever you are in the northern hemisphere.

• Ralph's top choices are for beginner astrophotographers, armed only with a DSLR camera and a telescope, and focuses on the Leo Triplet
• Paul takes five deep sky galaxy treats for visual astronomers in May and throughout spring. The prime pick is a tricky tricky double galaxy to test your skills and help develop your averted vision.
• John takes a look at the solar system objects available a little closer to home this month as he runs through the best of the planetary offerings and whets our appetites for the coming transit of Mercury on 9th May.

So welcome to AstroCamp and we'll see you very soon!
