I've recently set up a very wide field meteor camera using a Watec 902 H2 Ultimate with a Computar HG2610FCS/AFCS-HSP 2.6mm f1.0 lens. This gives me a great field of view. It's primary purpose is for detecting fireballs and recording general meteor activity rather than calculating trajectories. For this I have a second system with a Watec 902H camera and 3.8mm lens which I'm hoping to have up and running in the next week.
However, I thought it was worth trying to run UFOAnalyser on the wide field system to see if it can be used for scientific data gathering. I'm detecting stars down to mag 2.7 and can on a clear dark night I get up to 20 stars showing on the videos. The problem comes when I try to align the stars. UFOAnalyser seems to align the stars in parts of the field of view very well but won't get good alignment on all stars. The 'dpix avr' figure is around 5 and 'ddeg avr' is around 1. I've tried running the <SD command a couple of times, but this make little difference. This poor alignment is more noticeable as one looks towards the peripheries of the field of view. (My guess is UFOAnalyser is unable to correct for the degree of distortion at the edges that result from the wide field lens/dome combination). Is there a maximum correction factor that limits UFOAnalyser's ability to make these corrections and are there any settings that can be altered to increase this factor?
