One of the issues astro photography throws into the process is air movement which is constantly shimmering, like heat haze. The video technique allows the occasional image to sneak through in a micro lull of air shimmy, this for individual stars or planets, not constellations or nebulae.
I have just had a disastrous night, the conditions on Birker fell were poor so I decided to go down into Eskdale and see if we could find a location by the railway to get a nice Milky way shot but noting seemed to work, so we went off towards Hardknot, thinking we might set up near the summit but as we passed the Roman fort I hit a pothole with both n/s wheels, dinging the rims and resulting in deflation of both tyres, I swapped the front one for the spare, then quickly took the back wheel off and beat the rim back into shape with a nearby granite boulder, it stopped leaking so we set off back down with a very soft n/s back tyre. It soon heated up and regained some pressure, we pressed on back towards Ravenglass, there is a garage near the junction with the main road where I thought we might be able to re-inflate the tyre.
We got to the garage, I couldn't get the tyre inflator to pump the tyre up, running out of coin fortunately Christopher spotted a button to press for flat tyres...
Not a very good night.
