It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere. Maximizes the transmission of the main emission lines of the nebula in OIII (496nm and 500nm) and H-alpha (656nm). Used with DSLR, color\/MONO CMOS and CCD, however, this filter is not suitable for fast ratio systems.\u003c\/p\u003e\n\u003cp\u003eThe advantage of L-Ultimate is that it only passes through the emission lines OIII(500.7nm) and Ha(656.3nm), in which case all other light pollution emission lines are eliminated so that only the emission and reflection signals of the nebula are captured during imaging. Therefore, the sky background of the image is darker, and the contrast between the nebulae and the signal-to-noise ratio are improved to the greatest extent. In heavy light pollution areas, the product can also selectively filter light pollution and clutter signals through the emission lines of nebulae, and finally avoid the impact of light pollution on astrophotography.\u003c\/p\u003e\n\u003cp\u003eIt is different from the series of dual-narrowband L-eNhance and L-eXtreme in that L-Ultimate is a dual-3nm bandwidth filter that only passes through Ha and OIII emission lines. You will get a darker sky background, more contrast of the image and the suppression on stars. L-Ultimate has also been optimized in terms of halo performance, so that there is no obvious halo when shooting on a bright star object.\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003ctable align=\"center\" cellpadding=\"1\" cellspacing=\"2\" border=\"1\" class=\"alignleft\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSbustrate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eoptical glass\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFWHM\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eOIII 3nm Ha 3nm\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBlocking range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e300-1000nm\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBlocking\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e\u0026gt;OD4\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSurface quality\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e60\/40\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransmitted Wavefront RMS:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eλ\/4\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eParallelism\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003e30seconds\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eL-Ultimate Filter Performance\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eNebulae Flying Bat and Squid in the constellation of Cepheus.\u003c\/strong\u003e\u003c\/u\u003e\u003cbr\u003eSquid (OU4) is a region characterized by very weak OIII emission with a bipolar shape reminiscent of planetary nebulae.

Color CCD cameras such as the Skyris color planetary cameras are very sensitive across the visual spectrum, as well as in infrared. Some telescopes may correct for chromatic aberration, but are not designed to correct for IR light, which can often look defocused in astroimages. Blocking infrared (IR) light provides the greatest color balance and sharpness in your astroimages.

Will never develop pinholes or scratches that can let in light and ruin a filter. Other advantages: lightweight and does not require re-balancing tube assembly, will not break, consistent yellow-orange solar image, even density with any aperture, flat surface compared to other thin film filters that have wrinkles and creases. Will not tear or puncture. Stronger than any other solar film on the market. Also available in sheets.

The O.D. of our cells needs to be at least 1\/16″ larger than the OD of the telescope tube or binocular barrel etc. Choose the closest cell O.D. that is LARGER than the O.D. measurement of your instrument. Example: Part number S-4250 (4 1\/4″ O.D.) would fit instrument O.D. measurements from 4″ to 4-3\/16″. Do not choose a size the same as your O.D. since it will be too tight. Self adhesive felt is included for custom fitting. If your application requires additional felt; Velcro, felt, and other types of material can be found at most fabric or home improvement stores. We cannot take orders for felt.\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"253\" width=\"253\" sizes=\"(max-width: 300px) 100vw, 300px\" srcset=\"https:\/\/thousandoaksoptical.com\/wp-content\/uploads\/how-to-measure-od-300x300.png 300w, https:\/\/thousandoaksoptical.com\/wp-content\/uploads\/how-to-measure-od-100x100.png 100w, https:\/\/thousandoaksoptical.com\/wp-content\/uploads\/how-to-measure-od-150x150.png 150w, https:\/\/thousandoaksoptical.com\/wp-content\/uploads\/how-to-measure-od-180x180.png 180w, https:\/\/thousandoaksoptical.com\/wp-content\/uploads\/how-to-measure-od.png 512w\" alt=\"How to Measure Outside Diameter\" src=\"https:\/\/thousandoaksoptical.com\/wp-content\/uploads\/how-to-measure-od-300x300.png?width=700\" decoding=\"sync\" loading=\"auto\" data-tf-not-load=\"1\"\u003e\u003c\/p\u003e\n\u003ch4\u003eOPEN TRUSS TELESCOPES:\u003c\/h4\u003e\n\u003cp style=\"margin: 0px 0px 1.3em; padding: 0px; color: #666666; font-family: 'Public Sans', sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003eIf the solar filter is to be used on an open truss telescope, the open area from front (secondary mirror) to back (primary mirror) must be covered.

solar observation. CE \u0026amp; ISO Certified. Unlike metallized Mylar (commonly used in food packaging), our Polymers give a SHARP pleasing yellow-orange image versus unnatural pale blue. Mylar also reflects your eyes in the mirror like surface, making it difficult to see the sun and commonly has pinholes in the coating. The protective properties of our Silver-Black Polymer eclipse film are throughout the substrate so there is never a concern about safety.
