  1. Probably a beginners question this one, but here goes.... I was just wondering if it was possible to operate two or more cameras, controlled by UFOCapture, with the same PC? If it was 2 cameras to operate, you would obviously have to have two independent video grabbers set up via two separate USB ports and recognised by the computer as such. Setting up two grabbers would likely mean you would need to have two different (and fixed) I/O configurations to input into Windows Device Manager that identifies them as totally independent so the PC doesn't get confused. That's maybe more than a simple PnP task. And you'd obviously need, I'm guessing, two instances of UFOCapture installed (with presumably two licenses?) that recognises the two different cameras. Has anybody actually tried doing this? Would it even work? I'd be interested to know if anyone has experience of this.... Steve

    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.
  3. i have an ancient watec 120n (more about that later) but recently i purchased a ZWO AI120MC. i use a Computar 5 mm f/1.4 lens, sky studio pro software( interfaces with ZWO windows driver, cool!), xvid codec, 4 second integration. no guiding (of course). pointing at a circumpolar point north by north east approximately 45 degrees declination. i have been influenced by security and dash cams capturing, inadvertently, fire balls. why not do it on purpose? i have been for a few years now. sure, i capture meteors but mostly i get jet aircraft, satellites and... i upload videos to my youtube channel. everyone is invited to check them out. i also have orion all in one and an astroscope image intensifier on canon t1i and t3i. it is my opinion that there are more short dim meteors than long bright ones. there are more satellites than meteors and more jet aircraft than satellites. something else...you foe? cloudy nights? check out my star field time lapses. youtube, what can i say? full screen in darkened room, make sure the gear has HD in red, click and select if not. find an intriguing clip? get a youtube down loader for best quality on your local drive. try adjusting play back speeds.
  4. Just a reminder for you Shropshire/West Midlands folks, I'm arranging a low-key weekend of Perseid watching and general astronomy antics in Shropshire. Six quid a night, dark sky, friendly campsite. The details and some pictures are on my blog in the sig. Everyone welcome!

    Hi Everyone

    Hey all, Last summer I figured out how to capture images of meteors during the Perseid shower using my iPhone 6+ and the app NightCap Pro. Since then I have managed to grab over 200 of these speed freaks. I built a barn door tracker and learned how to drive it with an Arduino, Easy Driver and a salvaged bipolar stepper motor from a dead Epson printer. After numerous adjustments of the code to get the speed just so I can get 5 minute shots with little to no trailing in the wide field work I am doing. The tracker can run for about 5 hours before it needs to be rewound to the starting point. The variable interval setting in NightCap Pro is perfect for the kind of images I am after. Attached is one of those Perseids that started this whole affair well beffore my barn door tracker came to be. Of course this was enough to cause an addiction, and I bought a little Celestron C90 mak. I love the scope, even though it isn't an earth based Hubble. The erector prism is a joke as is the tripod and finder scope, but the main scope is a fine little machine. So far I have managed a few fair shots of Jupiter and Saturn, but my barn door tracker is not sturdy enough to carry the scope. In an attempt to overcome this I bought the iOptron Skytracker Pro and matching ball head. Let me just say I am far from impressed. This tracker is mounted on a 1/4" plate of aluminum which is in turn mounted to a water filled 55 gallon drum that serves as a large pier. My barn door tracker is also mounted to this plastic drum, and the barrel sits on a thick bed of crushed limestone. I also drove steel T posts into the ground nearly level with the barrel top, and then clamped all this together with a 1 ton ratchet strap. No matter how hard I crank down the setting knobs on the ball head the scope droops slowly to plumb. When I just mount my iPhone to the ball head this issue doesn't arise, and I have made 25 minute exposures with nice crisp stars. The scope is supposed to be well within the capacity of the tracker and ball head, but apparently is not. So, my next purchase, after months of research, is going to be the Celestron Advanced VX mount, and I may give the iOptron gear to a deserving kid. I don't care about serious deep field work, but the C90 can easily resolve more faint objects than I thought it would. Resolving the major moons of Jupiter is a trvial endeavor. The narrow field of view doesn't bother me at all. Perhaps I will buy a larger scope in a year or so and use the C90 as a guider. Some personal info: I am a retired 63 year old man and live off the grid in north central Arkansas Ozark mountains on 60 acres with my wife of 24 years. In a former life I was the executive director of a small natural history musem that focused on the terrestrial fuana of the very latest Cretaceous of the Hell Creek formation in South Dakota (when non-avian dinosaurs became extinct). Currently I am attempting to recover from a broken fibula that happened the second monday of March, but had a CAT scan last Friday in preparation for reconstruction surgery later this week. The breaks, yes multiple fractures, have failed to reunite as they should. This, of course, will mean a restart of the mending and effectively put my sky watching in a bind for another 6-8 weeks. Even if I am back on crutches I will be ready for the Perseid shower, and will probably visit with my son in Oregon to watch the total solar eclipse in August. So, here I am and eager to absorb the collective knowledge I have already seen is a commonality on your fine forum. Thanks for having me. Perhaps I can even contribute a few tidbits from time to time. Roger
  6. A meteor from last night's Perseid meteor Shower. It was a fantastic display - I've never seen so many meteors in one night, and really bright ones too. This is a single 30 second exposure at 1600 ISO taken at Ibstone Common (about 40 miles out of London).
  7. Hi did anyone else see that meteor burn up i was viewing skies east from middlesbrough uk and the meteor burn up was heading towards south was awesome seen trail then burn up shame me sky cams not facing that way would captured it was around 3:30 am Started up me fm scatter system see if any more meteor's View me radio astronomy thread learn bit of radio scanning. http://stargazerslou...53400-moonraker
  8. From the album: Cygnids in Jully 2019 from Bulgaria

    We carefully monitor the displacement of the radiant. It looks like a meteor shower!
  9. Hi 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? cheers
