Heresy, yes...
Let's face it, it is cloudy 94.57% of the time. We astronomers play with our gear, wistfully imagining that the skies might one day clear up enough to perhaps see the moon.
I have personally taken to shooting images of hummingbirds with a small refractor, a ZWO camera and SharpCap. Since the images have little integration time, I can't leave this running long or my computer would explode. There are other birds flying around that could be imaged in a similar fashion.
What I need is something to trigger the "sequence" when a bird lands on my target...

Re: Motion Detection
Hi,
if you have a relatively plain background then maybe the 'seeing triggered capture' mode of the seeing monitor might help? See https://docs.sharpcap.co.uk/4.0/#!2!Seeing%20Monitor
That functionality monitors the image for increases in contrast that are caused by periods of good seeing, but it might be possible to set it up to spot a period of increased contrast caused by a bird appearing in view? On the other hand, if the background is rather busy, then the bird appearing might reduce the contrast, which would not work
cheers,
Robin

Re: Motion Detection
Thanks Robin
The lens has a wide-open aperture (a telescope) so the depth of field is small, meaning the background is blurred. I'm also trying to align things such that the background isn't too busy. If a living nebula (e.g. a Robin) appears and is in reasonably good focus this might work.
I was unaware of this feature. Thanks again.
