IDAS NBZ - Astronomical Optical Filters
The NBZ is a dual band nebular booster filter that transfers OIII and H-alpha emission lines with the band width of 12nm (+/-0.4nm) at each band. Halos that occurred around the ojbects with the predecesor "NB X " filter can now be decreased 1/100th thanks to the technology we have developed to surpress the repetitive reflections of the filter ...
IDAS NBZ-II 10nm Ha & 8nm OIII Dual Band Filter - Agena Astro
The IDAS NBZ-II is a new dual band nebula booster filter - the successor to the NBZ (NBZex) filter. The FWHM of the NBZ-II is 8nm (+/=0.4nm) at OIII, and 10nm (+/-0.4nm) at H-alpha respectively. This has the same anti-Haloing characteristics as the NBZ did.
IDAS Nebula Booster NBZ
NBZはOIII輝線とHα輝線を透過するバンド幅約12 (±0.4)nmのネビュラブースターです。 フィルター単体の繰り返し反射を低減させることにより星像周辺のハロは、先行販売していたNBXの1/100と極めて写りにくいスペックとなっています。 概要で記した通り、NBZの半値幅は約12nmで、他社製7nmクラスのナローバンドよりも半値幅が広いです。 ですが、この広さには大きなメリットがあります。 干渉フィルターは斜めに入射光に対し、入射角が大きくなるほ …
IDAS NBZ-II Nebula Booster
The IDAS NBZ-II is a new dual band nebula booster filter - the successor to the NBZ (NBZex) filter. The FWHM of the NBZ-II is 8nm (+/=0.4nm) at OIII, and *9.5nm (+/-0.4nm) at H-alpha respectively. This has the same anti-Haloing characteristics as the NBZ did.
IDAS NBZ II Nebula Booster - 2" Mounted Filter — Starizona
The IDAS NBZ-II is a dual band nebula booster filter - the successor to the NBZ (UHS) filter. The FWHM of the NBZ-II is 8nm (+/=0.4nm) at OIII, and 10nm (+/-0.4nm) at H-alpha respectively. This has the same anti-Haloing characteristics as the NBZ did.
IDAS NBZ Nebula Booster Filter - 48mm - OPT Telescopes
The IDAS Nebula Booster 48mm Filter is designed to enhance the contrast of Ha (Hydrogen Alpha) and OIII (Oxygen II) emission nebula while accommodating the filter spectral shift when used with modern fast optical systems. This dual-band filter is ideal for one-shot color cameras, as well as mono-color astronomical cameras.
IDAS NBZ-II（Nebula Booster）・48ST2-ネイチャーショッ …
本フィルターはIDASの定番技術である高密度高耐久エージングレスIAD (Ion Assist Deposition=イオンアシスト蒸着)でコーティングされます。 この技術は干渉フィルターの心臓部である多層薄膜を高密度化するもので、従来の多層薄膜で得られない物性が得られます。 薄膜の耐久性が高く、薄膜の硬さは石英ガラスに匹敵します。 多層薄膜とフィルター基板の密着性も著しく改善されています。 温度、湿度による分光特性の経時変化は人間が生活している環境 …
IDAS Filter Comparison Test Report - Cloudy Nights
2021年11月9日 · For ability to increase contrast on emission type nebulae, I would rank the filters in the following order (highest to lowest): Optolong L-eXtreme, IDAS NBZ, Optolong L-eNhance, IDAS NB1.
IDAS Filters NBZ 2" - Astroshop
The IDAS-NBZ is a new, dual UHC narrow band filter for H-alpha and OIII ranges. It also counteracts light pollution and considerably increases the contrast within many nebula structures. The NBZ has a very high transmission of 96% and is in …
