Baader TurboFilm Experiment
02/04/2011. Having had the objective of my brand new Equinox 120ED Pro contaminated with bonfire ash I decided to try and protect it. Research led me to Baader TurboFilm so I bought some and took a chance. The image attached provides a side by side comparison of South and North towers of the Humber Bridge taken (through the bathroom window) with the EOS 450D, ISO100 and an exposure of 1/250sec;SW Equinox 80ED Pro on camera tripod. Image quality is hardly degraded (if at all), as photos were affected by a heat haze. I did notice that to get the same exposure I had to reduce speed from 1/320 to 1/250 though. Just need a deep-sky trial.
