All Sky Camera update – Long exposure/ Frame integration

Hi Folks

I’ve been experimenting with the All Sky camera setup to try and extend the total exposure time for an exposure. One limiting factor is the camera firmware which limits exposure to 1 second.

The way that iSpy gets the images from the camera is using a combination of RTSP (Real Time Streaming Protocol). The command line for that is the funny string of characters you entered when first setting up the camera (rtsp://admin:@

This is then passed into iSpy via FFMPEG software, which is basically a communications interface. Here’s where I’ve made a discovery. I can change the command line to allow frame integration of 2,4 or 16 frames i.e. 2s, 4s, 16s exposure.

I still have a little more playing about to do before I release the command line but it looks promising. The FFMPEG documentation is a nightmare but it’s incredibly powerful

Happy New Year from BASMO

New year celebrations caught by the all sky camera.

Below are the daily and hourly meteor counts for December, the peaks for the Geminids and Ursids are clearly shown. Unfortunately Graves went off line between 20:00 on 13/12/17 and 08:00 on 14/12/17. The increase in activity on 31st is beginning of Quadrantids, which will be peaking on the 3/4 Jan.

Here is a comparison with December 2016, Graves went off line last December for most of the 29th Dec.

This final plot shows the daily meteor activity throughout 2017, the major showers are marked, for more information on meteor showers go to

Happy New Year

Barton All Sky & Meteor Observatory (BASMO)

The Barton All Sky & Meteor Observatory (BASMO) is now operational with the addition of the All Sky camera and realignment of aerial which has started to work loose in mount. The radio section detects the reflections of the Graves Radar signal (near |Dijon) 143.05 MHz detected using the Yagi aerial( az 140 deg , inclination 20 deg) connected to a Fundongle pro+  and signal processed using SpectrumLab on laptop. The Allsky camera runs using Ispy and is set to record video if motion detected in the selected sectors. Unfortunately the All sky camera will not show the meteors detected by the radar ( usually over southern England/ channel/ France)

Images below as follows:

  3. BASMO Meteor detection top, allsky camera feed bottom.
  4. Radar meteor detection, long duration trace as meteor “burns” up leaving ionised trail
  5. Radar meteor detection showing Doppler shift of approx. 100Hz as meteor approaching Graves signal slows in atmosphere.
  6. BASMO  All Sky camera pointers.
  7. All sky camera and rain drops, design fault ,Ed forgot to include wiper blades!

Nice All Sky Camera timelapse

Hi Folks,

Here’s a nice little timelapse from a few days ago, edited using a free bit of software for windows called Shotcut ( It’s a bit like Windows Media player and VLC player but it allows you to export a speeded up video, which is very handy

This one is effectively running at 60fps and was a timelapse recorded on my All Sky Camera with iSpy recording at 1 frame per minute over about 6 hours, although, I’ve cropped this much shorter as it was getting light

It’s quite nice as you can see the Plough moving down the screen, and the after about 20 seconds you’ll see Cassiopeia coming in at the top right near the tree . You can also faintly see the Milky Way moving down the screen after that.

I think for a cheap DIY camera it’s not bad

Settings for Andy’s All Sky Camera 16/6/2017

For future reference for myself and also as a reference for others, the settings on my All Sky Camera can be accessed via links below. This is the camera I build at Ed Mann’s workshop. I have also included again another copy of Ed’s original instructions from which these settings were ascertained for my Dell Precision M4800 laptop and Dell Precision M6800 laptops – using the same All Sky Camera the settings are the same on both laptops. I am using VLC media player to play back recordings.
