Not surprisingly the guide graph was not the best but it was saying on the chart for the most part. I was prepared to drop back to 300 x 30 second subs if conditions demanded shorter subs. . I was watching the subs on the SGP display, expecting to have to go shorter or shutdown but while some appeared wind affected most were fine. Of course under the old model of plus 300 second subs they would all be rubbish. The obs walls are fairly high and that helps but the top of the scope and light shield sticks up into the wind. I suppose the large trees up wind help as well. I expect i will have to page through all of these subs tomorrow (today) and get rid of any outliers, but even if only half are useable i will be happy.
glen do you think short narrowband (20-30 seconds) will be achievable with the camera?
if you've got some wind affected subs try out average combine in DSS.
