Another clear night provided an opportunity to try out the cross-star "filter" with the Seestar S50. This filter consists of two rigid crossed wires. It is meant to simulate the diffraction spikes caused by secondary-mirror holders in Newtonian and Cassegrain telescope designs. It is purely an aesthetic effect.

The Cross-Star filter and lens shade are add-on accessories by Omegon.
