Planets are easily observed with urban telescopes. One of the biggest breakthroughs in the past 40 years for deep-sky enthusiasts has been the introduction of effective multi-layer interference filters for certain classes of deep-sky objects.  With filters, objects which might ordinarily be difficult to impossible to see in most amateur telescopes even under dark sky conditions come within range of the experienced observer.  Even those bright and easy “showpiece” nebulae often gain significant detail and contrast with proper filtration.  Some filters even allow urban or suburban observers to view certain objects under less than pristinely dark skies by reducing the background glow of the night sky.  Since they were introduced in the late 1970’s, these filters have become a vital part of the amateur’s “observing arsenal”.

Does not match with "intensifier", but if we think them as separate words, and not a phrase, it is Hoya - Red - Intensifier Filter, and Red here only indicates filter color, and not what it intensifies. However, since the bandwidth of the OIII filter is so narrow, it may hurt some nebulae with significant H-beta emission somewhat, like the nebulae around Gamma Cygni or the Horsehead.  This is one reason why experienced observers often have *both* a narrow-band nebula filter *and* an OIII line filter to cover all the bases.  Differences between the OIII filter and narrow-band filters like the Lumicon UHC are mainly in nebula visibility and contrast.  Many nebulae show a slightly larger area of nebulosity in the UHC filter with slightly higher brightness, but in the OIII filter, they will often have more contrast and dark detail.  However, the OIII filter really dims the view of star clusters and galaxies even more than the narrow band filters do, although observers with large telescopes may find the OIII useful for bringing out a few emission nebulae in other galaxies, like the HII regions in M33.  In addition, for the larger more diffuse objects, a selection of a fairly low magnification (3.5x per inch to 7x per inch of aperture) is sometimes helpful in initially viewing them with the OIII filter.  On smaller planetary nebulae that have high surface brightness however, the OIII can sometimes be successfully used to bring out some inner detail at powers up to around 50x per inch of aperture.  Thousand Oaks has produced its own Oxygen III filter (the “OIII LP-3 filter”), as has Astronomik, Meade, Orion, and a number of other outlets.  Baader’s OIII filter has a very very narrow passband width which has tended to cut into the 4959 angstrom OIII emission line a bit, although many amateurs still report good results with that filter. Thereafter, I’ll review my own light pollution filter – the Hutech IDAS LPS D1 – that I’ve been using to combat light pollution while imaging ‘broadband’ targets such as the Andromeda galaxy.

These scopes are about as hassle-free as a telescope can be and they look really attractive, so you might even find yourself leaving it set up all of the time (which is awesome because you don’t have to dig it out of a closet every time you want to take a quick look). Some available broad-band filters are the Lumicon Deep-Sky, the Astronomik CLS, the Celestron LPR, the Thousand Oaks Broadband LP-1, and the Orion SkyGlow.  The broadband filters can offer a modest boost in contrast and visibility of the fainter outer detail in emission nebulae over non-filtered views for objects like the Orion Nebula (M42), the Lagoon Nebula (M8), the Merope Nebula, the Trifid (M20), and a number of others.  However, the improvement is not as noticeable on star clusters or galaxies.  I have found that using the filter on larger and more diffuse galaxies like M33, M81, M101, NGC 253 and NGC 2403 in my 10 inch when weak skyglow is present will help boost the visibility of the detail, but the effect is fairly mild.  On star clusters, there is even less of an effect, since some of their emission falls in the portions of the spectrum blocked by these filters.  In that case it may be better to use slightly higher power on some of the smaller objects to dilute the light pollution effect a bit.  Since some light is blocked by the filters, there can be times when a few objects may even.
