Description

My first shot on the Iris Nebula. When my telescope was set up I thought it will clear the trees soon... a mistake. I decided to image two objects: M27 again and the Iris Nebula. However, after 1,5 hours I decided to unmount the OTA and counterweights and set up the Telescope three meters westwards. Maybe I should have done this right at the beginning...
