  1. Finally got to grips with my cheap Chinese 3D printer and am making proper end caps now, should be usable this week.

  3. Having watched some youtube videos of the stars through night vision devices i wanted to do the same and see it for myself, the light-gathering power of the P8079HP is impressive, the manufacturer's manual says it multiplies incoming light by 100,000. Some specs on the tube here from the manufacturer's manual : https://www.dropbox.com/sh/rnnkvasq5t6o2dy/AADmr9Ftu9FrdnRR2OohXQJpa?dl=0 It takes from 5 to 6.75 DC at 35mA max in my experience though the manual says 50mA max, these tubes are old so mileage varies. To use it as a stand-alone unit it needs an objective lens in fro
  4. Thanks for replies, ended up getting a raspberry pi plus the IR camera. I was hoping i'd see something in the sky but i've seen nothing, i suppose the sensors are short-range, should probably read more before embarking on these projects! What i have been wanting to do for years is skywatching with night vision, i finally bit the bullet and got one of those P8079HP NV cascade tubes, it's nearly done, will post a thread on it. Cheers and beers
  5. Lots of videos on youtube, mostly using a 35mm film tube for a housing but i can't find one that's about removing the IR filter AND attaching to a scope. I opened up my logitech C270 webcam but the filter is part of the surface-mounted CCD chip so i'm not touching that, i need one where the filter is part of the lens assembly so that it's easily removable, or even breakable, but also one that is easy to fit to the star diagonal. Any advice/experience/failure stories greatly received
  6. Were the Orionids busier than usual this year? I can't find after-reports but a few of my friends saw more than one, which is unusual judging by what pals have seen in previous years here in Leicestershire.
  7. Ah, thanks rocky, i get it now. I have to read up on the basics of it all, so much i don't know!
  8. Yes, i spent ages trying to dissuade flat-earthers and the like but they seem to be willfully ignorant, and don't get me started on Nibiru and 'second sun' channels, they end up blocking me!
  9. Well i thought i'd ask the experts I still don't quite understand though, i understand about the secondary mirror,but i don't understand why the dark disc stays in the centre of Mars when the telescope isn't moving, i woudl have thought it would appear to edrift to the left as Mars moves to the right?
  10. If it is an obstruction, i'm wondering why it moves with Mars and not his scope?
  11. I think he's just looking for mysteries and seeing what he wants to see. I love mysteries but there's nearly always an ordinary explanation for them.
  12. An amateur astronomer has a video of Mars but there's a dark circle in the middle of Mars. Ignore the UFO in the title, he admits he's not experienced, it obviously isn't a UFO (or an asteroid as he says at one point!) since it moves with Mars, so it must be some kind of optical effect ?
  13. I was wondering about how it would be done programmatically and then stacking came to mind, his hardware setup is pretty busy!

  15. Yes i think you could beat 1M. I know how long it takes,i started manually, then i built a jig operated by electric drill, then years later i bought this freom ebay : http://lechacal.com/wiki/index.php/Albawinder
