Placing Orders


Below are CCD images taken first without and then with an IDAS LPS filter (smaller images are the corresponding flat field frames). These images were taken by Mr. G. Tomita from the heavily light-polluted Tokyo metropolitan area. using an SBIG ST-8E CCD camera coupled to a Pentax 125SDHF (125mm objective, 800mm focal length) refractor. Note the improved detail in the faint areas of M27 when the IDAS LPS filter is used.
