This results in minimal colour cast on broadband emission targets such as galaxies, reflection nebulae and globular star clusters. Often emission nebulae are embedded in dusty areas which reflect light and these details are \"lost\" with Narrowband, UHC and CLS filters which transmit emission wavelengths and not much else. The LPRO MAX not only allows all the usual emission wavelengths through, but it also allows better visibility of dusty reflection nebulosity and dust. Both emission and reflection nebulae are covered with the LPRO-MAX.\u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eMilky Way wide field imaging:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe LPRO-MAX specially tuned passband gives an even more natural colour rendition than CLS or UHC filters because it allows more starlight through than UHC and CLS filters, giving a more natural looking milky way.

LPRO-MAX blocks UV and IR light, for sharper stars. Mono cameras can also be used with the LPRO-MAX to capture Luminosity channel in LRGB imaging in light polluted areas. The LPRO-MAX 2\" filter is compatible with the entire Altair GPCAM range, Hypercam CMOS cameras (the LPRO-MAX screws into the front 2\" nosepiece of the camera or the Altair Magnetic filter holder with 2\" slider). The GPCAM \/ Hypercam DSLR lens adapter is also compatible - the LPRO-MAX 2\" filter fits inside the housing behind the lens, protected from dust.\u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eVisual use\u003c\/strong\u003e: LPRO Max is a good choice for visual use where one desires to see galaxies and stars as well as nebulosity.

Scattered and reflected glow from commercial LEDs used in streelighting is also significantly suppressed.
