In parallel with spectroscopic targets, photometry can be performed using viewfinder systems (150/1200).
One of the structurally identical viewfinders is equipped with a C4-16000 CMOS camera (Moravské Přístroje) – ONDCam, which allows the use of 6 different photometric filters (Sloan g’, r’, i’, z’, H-alpha, and cmos B-band).
The second uses an ASI2600 CMOS camera (GrazCam system) with 7 filters (Sloan u, Johnson B, Sloan g, Johnson V, Sloan r, Sloan i, and grism SA200; No. 8 is free). For use with SA200, this system is equipped with a field rotator.
