IC 1805, IC1848 - 12.3.2015 at 21.00 Uurainen Observation number 34186

Visibility II / V

The old 135 millimeter refused to focus with an infinitely modified camera but luckily the cls-clip filter brought help. At the same time, I tested how the front Aperture mask carved from a tent mattress with a carpet knife works.
