Hi there,
please note that today, 8th december 2021, we swapped the Ha filte ron the iDK 20 in Namibia. We went from 3.5nm to 7nm bandpass, which shall allow for 2x faster data collection under those dark skies. We also cleaned the filters which had sort of a "hue" of very fine sand on them.
New flats will follow asap
Best regards
Lukas
