New telescope first light

My old 6 inches newtonian served me well for over two years, but finally I managed to complete building of the new 8 inches fast f/4 newtonian. I have made carbon fibre tube by myself and then equipped it with all necessary devices – mirrors, mirror cell, spider, focuser, dovetail, astrobox (with USB hub and focuser controller) and others.

First light – M1 Crab nebula. Still needs some adjustments in collimation, but looks promising 🙂
