Chromatic aberration (Effect) - Filter Forge

In professional astronomical observations, filters play a small but vital role. Sometimes some important astronomical discoveries are made possible by a small filter. In the past decade or so, astronomy enthusiasts have increasingly discovered the importance of filters. In the field of photography and observation, chromatic aberration of telescope lenses has always been a problem that troubles you. It causes image distortion, and inaccurate tonality, and degrades the visual experience. However, now we have a brand new solution, the SV231 chromatic aberration filter. Let’s take a look.Chromatic aberration filters are highly anticipated as a powerful tool to solve the problem of chromatic aberration. Our filter uses advanced optical technology to effectively eliminate chromatic aberration and make imaging clearer and more accurate. Whether it is astrophotography or bird observation, it can significantly improve image quality and bring more realistic and natural color presentation. In addition, we also provide two sizes of 1.25 and 2 inches, so you can choose freely according to your needs.SV231 is treated with high-quality coatings and has excellent optical properties. It enhances contrast, reduces reflections and scattering, and improves image detail. In addition, this chromatic aberration filter is made of high-quality materials and has excellent wear-resistant, scratch-resistant, and waterproof properties. It can be used in various harsh environments and has a long service life. This filter also uses a double-sided thread design to support the stacking and use of different filters. Makes filters more flexible and compatible. You can try using other types of filters to capture the light you need for a better experience, which not only saves costs but is also simple to operate. Overall, the dual-thread design of our SV213 chromatic aberration filters provides greater flexibility, compatibility, and combination options. It is easy to carry and store, and more economically efficient. This gives the observer greater control and adjustment of image effects.Chromatic aberration filters are widely used in the fields of astronomical observation and bird observation. It can not only improve the quality of observations of galaxies, planets, and other cosmic objects, but also make the colors of bird feathers more realistic and natural, and the details more clearly discernible. Whether you are a professional photographer, astronomy enthusiast, or bird watcher, chromatic aberration filters are indispensable for.

The problem is then that your camera does not see that type of colour anymore though.You can get rid of chromatic aberration automatically in Lightroom and Photoshop. Provided its not thick or its not creating purple/green blobs in your image you can fade it to grey and never notice that it was there. Some cameras (Panasonic Micro Four Thirds) do this automatically for you.In any case... Leave the CA and deal with it if its serious in post processing. Olympus OM-D E-M5 Olympus M.Zuiko

Meaning cheaper eyepieces tend to work better with them. However, at low power field curvature can be a nuisance (even more so when imaging) and cheap eyepieces may worsen chromatic aberration in achromatic instruments.Disadvantages of a refractor telescopeThis is not to say, however, that refractors don’t have their disadvantages; among them:You can’t get a big one – Commercial refractors top out at 6” in aperture, and most of these are enormous instruments that rival a 12” catadioptric or 16” Dobsonian in bulk and cost. 7”, 8”, or even 9” refractors pop up occasionally but often cost as much as a sports car or even a home, and usually need a permanent observatory to support them. Meanwhile, a 10” Dobsonian can be easily carried in one piece and costs less than a 6” refractor and mount.Chromatic aberration – Apart from their small apertures, chromatic aberration is the bane of refractors. The cynical would say that the definition of an astronomer is someone willing to spend a fortune to make a little ring of purple go away – and they’d be right. Inexpensive refractors are almost always achromats which require long focal ratios and, consequently, long tubes and narrow fields of view to minimize chromatic aberration – the ugly purplish halo around bright targets caused by the inability of the objective lens to focus all colors to the same point. Apochromatic refractors are heavier and more costly, with many often still suffering from some chromatic aberration – particularly those made for imaging. The best refractors, free of chromatic aberration or optical defects and made for both imaging and visual astronomy, have eye-popping prices – often several thousand dollars for something just 3” or 4” in aperture. The views and photos produced by these instruments are spectacular – but remember, a small telescope

There are plenty of excellent lenses around these days, but the best are not cheap.I think that is the point of the chart I posted above. Lenses that correct CA, fold the spectrum back on itself, so multiple colors will be in focus at the same point. You can draw a vertical line anywhere in the chart, and where ever it aligns with more than one color at a time, they will both be in focus. You could get a large portion of wavelengths in focus with a green filter, but paradoxically a magenta filter that notches out green also has a low degree of focus error.I wonder if there are any dual bandpass filters that select for amber/orange and sky blue or teal?

Other trips where you may not be able to guarantee favorable weather conditions.One of the main issues with refracting telescopes is that they can often suffer from spherical or chromatic aberration – the exception here is apochromatic telescopes. The lower the f ratios, the greater the risk of this aberration.Before we take a closer look at the details of spherical and chromatic aberrations, it is worth mentioning one final type of telescope – catadioptric telescopes offer a hybrid solution, combining reflector and refractor telescopes.What Are Spherical And Chromatic Aberrations?It is worth taking a moment to further explain the difference between spherical and chromatic aberration and the significance of these concepts.In the simplest terms, aberrations refer to imperfections in the optics of the lens of the camera and will cause the deterioration of an image that is captured. Different types of lenses will be affected by aberrations to a range of degrees.Spherical AberrationSpherical aberration occurs on spherical surfaces and lenses and occurs when light rays that pass through the lens fail to come together in a single focal point. Instead, light rays that strike the edges of the lens are refracted differently and come out at different places to the rays that pass close to the center.These peripheral rays on the edge come out too bent or not bent enough – these are referred to as positive spherical aberration or negative spherical aberration. Rays on the edge of a sphere bend more than those passing through the center and so refract more.As rays of light hit the spherical lens at different spots hit different places across the optical axis but never converge together in a single focal point. This means that the image tends to be distorted rather than sharp and clear.Spherical aberration is usually caused by lens design – shorter. Chromatic aberration filters, as the name suggests, are used to counter chromatic aberration. Chromatic aberration, or optical aberration, is a common problem in refracting telescopes.

Focal length lenses more frequently suffer this problem than longer ones. Poor-quality glass can also increase the risk of spherical aberration, as does the placement of the lens inside the casing of the telescope.Chromatic AberrationChromatic aberration is similar to spherical aberration in that it involves rays of light. Still, in this case, the issue occurs when the rays of light passing through the lens focus at different points according to their wavelength rather than the shape of the lens.Chromatic aberration comes in two types: axial and lateral. Axial chromatic aberration occurs when there is a variation in the wavelength of each wave of light, resulting in blurred colors behind and to the front of the color’s focal point. In contrast, lateral aberration, refers to variations in the magnification of colors.At the periphery of the image, lateral aberration will be more visible. Chromatic aberration can be reduced using an achromatic refractor, or an apochromatic (APO) refractor.Achromatic RefractorAn achromatic refractor is a useful way to help reduce chromatic aberration. Remember, refractors use their lenses in order to gather light – this is their primary means of gathering light. The convex glass lenses of these telescopes mean that color can be distorted as the different wavelengths of light focus at different points throughout the lens. The resulting color in the final image is then distorted. Achromatic refractor lenses use “elements” – multiple pieces of glass, each with their own unique characteristics and differences in the way that the light is dispersed into the light of the lens – and combine two or more “elements,” carefully matched to ensure partial correction of the distortion. Color fringe may still occur with an achromatic refractor, and this is likely to have to be corrected digitally.Apochromatic (APO) RefractorAPO refractors are like an advanced version of achromatic lenses

102 and AZ-GTe mount also can fit in a backpack or suitcase, making it great if you travel frequently, don’t own a car, or simply want an ultra-lightweight and portable telescope.The main drawback to this instrument is the massive amount of chromatic aberration a 102mm f/5 refractor has. The StarTravel 102 Refractor has very poor performance on the Moon and planets and basically cannot handle over 80-100x magnification. (the included 25mm and 10mm Plossl oculars, both 1.25”, provide 20x and 50x, respectively). The scope does have a 2” focuser, so for the widest field possible you could conceivably attach a 2” diagonal and 2” wide-angle eyepieces – though the GTe may not be happy with this and you may need to actually purchase a counterweight for the mount.As with all of the StarTravel telescopes marketed by Sky-Watcher, the optical tube and mount use interchangeable Vixen-style dovetail plates. Sky-Watcher markets the AZ-GTe with larger and smaller refractors and Maksutov-Cassegrain optical tubes, which are all also worth consideration.Explore Scientific FirstLight 102mm Doublet Refractor w/ Twilight I Alt/Az MountBest Between $700-$1000FEATURES: f/9.8 aperture, 1000mm focal length, two 2.5” hexagonal Crayford focusers, and 25mm Plossl Ocular with 40x magnificationBENEFITSHigh-quality optics have little chromatic aberrationWell-made focuser can hold any eyepiece or diagonalRock-solid and easy to use alt-azimuth mountThe FirstLight 102 optical tube is incredibly well-made, with high-quality baffling on the interior, a rubber-lined dew shield, world-class optics, and a high-quality 2.5” hexagonal Crayford focuser designed for the heaviest of eyepieces or cameras.Being an f/10 achromat, the FirstLight 102 has some chromatic aberration, but compared to shorter scopes like the StarSense Explorer DX 102, it’s negligible.

The AVX 6” is a massive, 6” f/8 achromat atop Celestron’s Advanced VX GoTo computerized German equatorial mount. This scope has similar views to an 8” Dobsonian or 8” Schmidt-Cassegrain, albeit in a bulkier package. There is some chromatic aberration even at f/8, as large refractors have more chromatic aberration than their smaller counterparts even at the same focal ratios. The scope’s optics are pretty good, and the focuser is a beefy 2” rack-and-pinion unit. Setting up the AVX 6” refractor is a commitment. You have to assemble the mount with the tripod legs fully extended, put the scope on top, balance the scope in its rings, install and balance the counterweights, level the mount, polar align it, and then align the GoTo system. Once done, however, you’re rewarded with a powerful – if gigantic – telescope that will happily swing to and track any target you choose. The Advanced VX 6” includes a 9×50 finderscope which is arguably overkill for the task of simply aligning the GoTo system of the Advanced VX mount, a 1.25” prism star diagonal, and a single 20mm Plossl eyepiece providing 60x. At the minimum, you’re going to want more eyepieces, a polar scope for accurate polar alignment, a power supply, and probably a pier extension for the mount so you don’t have to extend the legs all the way. A WiFi adapter, 2” accessories, etc. also wouldn’t be a bad idea. You’re looking at spending quite a bit more than the sticker price of this scope to get the most out of it.While the 6” f/8 refractor optical tube is not really designed with astrophotography in mind due to its long physical length, long focal length, and chromatic aberration, you can stick other, more astrophotography-friendly optical tube assemblies such as a fast Newtonian astrograph
