Description

between the cloud gaps of the western lowlands and some cirrus clouds (moon still at 65%) I could capture first images with the IDAS NB1 filter. The result convinced me - a real contrast booster!

Still inexperienced I started with a shooting sequence of 50 seconds, which I courageously extended to 90. - To my surprise, the density of information increased without the sky background changing.

Where is the limit now? This was at 120 seconds - but not through the filter but through the circling. In total I could generate one hour exposure with 100 pictures.
