i have a few bits and pieces of space stuff i have collected over the years. I have never owned a meteor though and i thought it might be nice to start a little collection
has anybody on here got a collection and if so could you give some advice please
looking on ebay there are lots but i really dont want to buy a piece of african quarry or something from someones back yard!
i realise there are many types and various areas of the world that produce but how can a novice tell that they are genuine and are there reliable/ reputable dealers or sources available?
Talk by Alex Pratt, BAA Meteor Section
Free admission and visitors always welcome.
Visual observation of meteors has been a popular pastime for amateur astronomers for many decades. Using the naked eye, sometimes assisted by film and digital cameras, observers have contributed to our knowledge of the annual meteor showers. However, interest in visual observations is dwindling because of the extent of light pollution across our towns and cities.
Increasing numbers of observers are using video cameras, which can record meteors from suburban locations and in moonlight. Alex has observed meteors for many years, is on the Committee of the BAA Meteor Section and is a member of the IMO. He is co-founder of NEMETODE, a network of video meteor cameras in the British Isles.
His talk outlines the developments from visual work, film and digital cameras, to video techniques and describes setting up a video meteor station. The talk includes results from meteor cameras operating across Scotland.
This is one of the images I took on Friday night whilst trying to catch a Perseid or two.
Think there's at least 10 satellite trails on this 10 second sub which just goes to show how much stuff we've sent up there.
Are there any good sources of info on how many satellites are launched each year or how many are up there now?
So I was out the other night collecting images for a star trails of Ursa Major over the top of my daughter's tree in the front garden. Out of curiosity more than anything, I thought I'd give time lapse a shot. The attached is low res as I'm still messing around with what codec etc works best. The original avi file was pushing 8gb for 7 seconds!! Managed to get it down to 22mb but can't find anything inbetween. I'll keep playing though.
Original raw files cleaned up in Lightroom, then exported out as Jpg's into After Effects. The trails image used the same Jpg set but was put together in Star Stax. As pretty much first attempts at both, I'm happy.
