This is one of my "must have" objects.
The supernowa remnant in Cassiopeia is extremely dim. With F/3 OS Veloce RH-200 I need 10 hours of imaging for Ha to have correct SNR.
There is also small VdB 159 - blue nebula and star left down from CTB circle.
Veloce, STL 11000, EM-200.
HaRGB- 600:30:30:30.
