Just managed to catch Comet Catalina C/2013 US10 in between clouds,light pollution and the upper twigs of our hedge. Could not use my big refractor so instead tried with my Altair 66mm travel scope on Star Adventurer mount. Me, tripod, mount, telescope and DSLR all perched against the wall of our house, in the one position where I could see the comet. Sadly the clouds rolled in before midnight when the council turn off the street lights. 20 lights and 10 darks stacked and processed. No field flattener.
