IDAS NGS1 Broadband Nebular Filter for Astrophotography with IR Block - T2 thread

Name: IDAS NGS1 Broadband Nebular Filter for Astrophotography with IR Block - T2 thread
Brand: IDAS Filter
SKU: NGS1-M42
Price: 182 EUR

IDAS NGS1 filters enhance the contrast of astronomical emission nebulae against a sky with both man-made and natural sky glow sources.

Mounted filter with T2 (M42x0.75) threads on both ends - internal/external

The effective optical length is 7.5 mm

The filter is perfectly suited for the Celestron RASA 8" when used with cameras featuring a 17.5 mm flange focal distance and a T2 mount

Also suppresses parts of the spectrum of white LED lights

Ideal flat-top and moderate bandpass to prevent transmission loss due to spectrum shift on todays ultra fast optics and fast camera lenses

Steep bandpass edges minimize internal reflections

Excellent in-band transmission

Near IR (NIR) is blocked up to 1200 nm, eliminating the need for an additional filter to block IR.

1.1 mm glass thickness (parfocal with other IDAS LPS filters)

Incorporates IDAS-proprietary MBT, UFP, and IGAD technologies for highest optical performance

Made in Japan

Manufacturer: IDAS Filter

Product number: NGS1-M42

IDAS NGS1 Night Glow Suppression Filter

IDAS NGS1 (formerly LPS-D3) filters enhance the contrast of astronomical emission nebulae against a sky with both man-made (including white LED lights) and natural sky glow sources, yet preserve color balance of broadband objects such as galaxies. As with other IDAS interference filters, the bandpasses are designed to accommodate the steep ray angles of fast optical systems (f/2 as fastest).

The most important spectral lines of hydrogen (H-alpha, H-beta, H-gamma), oxygen ([O III]), sulfur ([S II]) and comets (C₂ in the head and the coma, CO⁺ in the ion tail) are transmitted.
