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.


Main 8 inches f/4 mirror in the cell and aperture mask


Focuser and Arduino based astrobox controller during final tests


Telescope top view with both cameras and filter wheel attached


Piggybacked lens for simultaneous wide field imaging.


In the field, before first light


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