Filter wheel 8 places for 50x50mm size, 5mm thick filters
Filter sets Bessel (UBVRI), SDSS (u'g'r'i'z'), etc.

If 2Kx2K CCD-camera Andor DW-436 is used, the field of view is 8'x8'.

There is also a possibility to use fast 1Kx1K electron multiplying CCD-camera Andor iXon DU-888. In this case the FOV is 4'x4', and frame rate can be set to up to few hundreds Hz, when small part of CCD is used. (more details ...).
