Description

Testing Meade ACF for DSO, I still have some problems with OAG (really hard to get both camera and guider camera have the same focus) but it may work well. Cloudy nights but I still tested the setup. I tried 300 sec. exposition, than 600 sec. Without a reducer the scope is dark but still works, needs more exposition time. Stars are quite round, with Antares reducer stars in the corners are over-corrected, another way of coma.
