This year's European AstroFest conference and exhibition. It is a 2-day event on the Friday+Saturday. They've now got the conference schedules (http://europeanastrofest.com/conference/) up and there are tickets left for the talks sessions (which include exhibition access for the whole day even if you only buy a single talks-session ticket), and £8 exhibition-only tickets if you don't want to spend much but like looking around the stalls (many will have show discounts, typically ~10%). You may not be able to get conference tickets on the day (see the site) but exhibition-only tickets should be available on the door if your decision to go is last-minute. The exhibition was £8 alone per day in 2015, with many well-known astronomy company names attending with gear for you to see, and often some show deals (though its varied in previous years). You'll get a better deal booking for any of the conference sessions, you can move between the exhibition/conference as you wish if you have the right conference ticket through the day. The conference is split into 4 sessions; 2 on Friday (10th), 2 on the Saturday. Each session is basically a half-day with a break and has ~4 talks. You buy tickets for any sessions you want to attend (per session, not per day or per talk). The website (linked to below) has talk details.
