Info from Daystar:
ATM series filtering systems appear similar to the University series but lack their uniformity, regardless of that for most users the ATM series provides wonderful visual and imaging fidelity at an affordable cost. Smooth spectral uniformity offered by instrument quality etalons satisfy the needs of most observers. Informative filtergrams can be made with slight dodging in the darkroom. Nominal at f/32, (full aperture or stopped down) with optical systems delivering an effective focal length of up to 2000mm the user will find the spectral uniformity of these filters impressive. The ATM series were available in a bandpass range of from 0.95Å to 0.50Å. The ATM series incorporate a cylindrical temperature regulated oven similar to that provided with the University series filters. If the main stay of the observing program concentrates on filtergrams and CCD imaging, then we suggested clients consider the advantages of the University (now improved with the QUANTUM PE) series filter. If the main desire is for visual work and taking basic filtergrams, these could be an excellent choice. During the course of manufacturing a filtering unit, each is thermally tuned by a precision factory-calibrated oven to maintain proper bandpass tuning. We continue to be amazed by images and views delivered by these systems.
