The JMI EZ-Align Polar Scope

Above : this image is an unguided exposure, on the DEC axis only but selfguided on the RA axis, of 5min. taken with my old 12" LX200 (classic) at f/6.3 (1922mm) and my old SBIG ST-9E CCD camera. The Polar Alignment has been made, in a few minutes, only, thanks to the JMI EZ-Align polarscope. The primary mirror of my 12" LX200 (classic) has been locked down thanks to the ScopeStuff Mirror Lock system.

We can see the stars are really rounds, no DEC errors. The EZ-Align is very accurate.
