  1. 115' from me is east of the Graves bearing but I have a much lower horizon in that direction. Directly at Graves I have a fairly sizeable ridge in the way. The pickup beam on my Yagi is about 60' so essentially I'm looking at approx 85' to 145'. I do get fewer hits than those in the South of England but I do get them. 2.00 am to about 8.00 am seems the best time for me. I agree Spectrum lab is the way to go. Sitting listening for pings is soul destroying. Good luck. David
  2. I'm getting reflections from Graves up here in County Durham but found that two things made a difference as at first like you I wasn't getting anything at all at 143.049. I. My rtl sdr dongle displayed frequency wasn't accurate. I needed to set it at 143.048 displayed to get 143.049 actual. Your offset may be different. It also alters with temperature. There's a vhf beacon near maidstone which transmits at 143.430 which you might be able to use to calibrate your frequency if you can get line of sight. Look up gb3vhf on google. 2. I got better results with my yagi oriented horizontally and pointed at 115' from my location which is somewhat east of the Graves bearing from me. So It might be worth experimenting with different frequency offsets and different antenna bearings. Cheers David
  3. Steve, Try here http://radioastronomy.me.uk/html/script_for_automatic_meteor_event_recording.html This may be the one you want. Regards David
  4. Using a tripod on windy conditions it can help to hang something heavy like a camera bag underneath the centre column of the tripod. There is often a handy hook there for just that purpose. It really helps with stability.
  5. I had two sessions in the observatory in December both beset with technical problems. Went out last night and it poured with rain ten minutes into an imaging run. Out tonight and only managed 30 minutes of imaging before the clouds rolled back in. The winter of 2014/15 was much better.
  6. I have an 1100d which I originally used for daytime photography and also astro with an ED80pro scope. Easy to attach, light weight on the end of the scope. Easily controllable from pc or laptop with the native Canon software or third party programmes like APT or Backyard EOS (both very good). Mine is astro modded now but I got some pleasing results even unmodded. I think the 1200d would be a good choice.
  7. Went out six o'clock. Clear skies. Opened shed roof. switched everything on. Started to rain. Shut roof. Rain stopped. Opened roof. Went into warm room. Funny noises on roof. Really heavy rain now. Closed roof again. Half an hour later clear skies. Tried again. Mount working, camera working, guide cam working. Five minutes into first image computer crashes. Rebooted everything and finally by seven thirty I can start imaging. I sometimes wonder why we bother!
  8. I'm fairly sure there's a video on harrysastroshed.com that covers comet stacking.
  9. Saw the ISS go over through breaks in the cloud at 5.37. Went out to the observatory at 6.30. Had an hour viewing and imaging the moon then the clouds rolled back in. Still, better than nothing. First time I've managed to get in there for weeks.
  10. Aaaargh indeed! I haven't got a view from my observatory so have been trying from an upstairs window with a non dslr camera and 400mm lens. Got it all set up and acquired and then couldn't remember how to switch to manual focus on a camera I don't use for astro very much! Wasted 10 mins and only got a few frames as the moon was disapoearing behind the trees. Still a magnificent sight regardless. If only all our kit was as uncomplicated to use as our eyes! Good luck for the rest of your sequence.
  11. Unfortunately not visible from my observatory because of houses but I have been watching it from my bedroom window and getting a few photographs. Disappearing behind the trees now and I'm freezing so back to bed. A glorious sight and well worth getting up for.
  12. Just come in after a couple of hours. Saw 19 with three really bright ones. Best was about 22..15 just west of Cassiopeia.
  13. I saw one very faint one at 10.00 pm. Had the meteor cam on motion detect all night and didn't get one! too much moonlight I fear.
  14. Just getting into using video and motion detect for meteor capture. I know when I'm looking at an aeroplane trace. On,off,on,off etc Can those more experienced look at these two jpeg composites made from avi's captured last night and confirm or otherwise. 1. Object moves quickly, trace gets brighter and then dims quickly in under 1 sec. Meteor near Gemini 2. Object moves slower, trace gets brighter slowly and then fades slowly over a few seconds Iridium Flare near Urse Major Thanks
  15. Chasing clouds up here in Durham but managed to see 17 since 10.00. Only caught one on video though. Best one came while I was adjusting the camera!
  16. i've got one from here www.lakeside-astro.com/ works well for me.
  17. +1 for the HandyAVI software. I use this for meteor detection with a Samsung SDC435 running through a capture card and it works very well. I also tried the software it in daylight with my recently acquired ZWO ASI120mm and it seemed to work ok detecting my hand waved about in front of the lens but I haven't had a chance to try for real under dark skies.
  18. The whole family got a great view if the pass last night. They were all very impressed.
  19. Thick cloud when I went to bed. Woke at 3.40 and looked out. Crystal clear. Thought about getting up and going into the observatory. Glad I didn't. Within 20 minutes it was pouring down! Sent from my iPhone using Tapatalk
  20. Very nice shots with this great little camera. I too have just got one and I am very pleased with the results. I've just got a filter wheel and filters and I'm looking forward to doing some lrgb imaging if only Jupiter would come out from behing the clouds!
  21. Four panes with quite a lot of overlap. David
