All Sky Camera

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)

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 (https://www.shotcut.org/). 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.

iSpy software – Very useful tips

  1. Look at the iSpy help pages – they are very comprehensive and helpful
  2. If you are using a mouse with the centre roller (most of them are like this now), when the mouse is on the main camera screen, you can use the centre roller to zoom in and out. It zooms the picture AT THE POINT where the cursor is. Try it – you’ll see what I mean. This is very handy for focusing
  3. To get into the camera settings URL in your browser there are two ways:-
    1. Right click on the main camera screen and select the first option Open Web Interface
    2. Open your browser and type in the URL 192.168.1.18 (assuming you haven’t changed the default IP address)
  4. At the bottom of the main iSpy screen, cliick on Performance Tips to get some very useful info about how to reduce the CPU loading and probably speed things up. This includes a major step like changing the video file type from MP4 to AVI on the Recording tab under Profile
  5. When I am adjusting  the camera settings, I reduce the size ot the camera settings screen to about half of the screen and then you can see iSpy behind it to see the effect of your changes

More to follow……

All Sky Camera information

HI Folks

Andy has created a new category for all All Sky Camera information under Equipment for astronomy – All Sky camera

As you have probably from the workshops, we are only scratching the surface of the ablilities of both the the iSpy software and the camera modules. I still have have a load of information and helpful tips to pass on, so over the next few days I’ll be adding more blogs in that category.

It’s probably worth checking what’s there

Cheers

Ed
