  • Information on backorders/release of 17.5 mm Morpheus® 76° widefield eyepiece

    For the Morpheus® 17.5 mm we have gone a very long way to end up with a perfect product. It definitely took many more iterations than we had in our planning. The Morpheus® eyepiece design at 76° of field does sound very moderate when compared against the far greater advertised apparent fields (and Cost!!) of those 82°, 92° and 100° eyepieces presently offered. The optical design is at it´s very and absolute limits. Image of one of the many Morpheus® 17,5mm prototypes - incl. new rubber eyecup with built-in M43 metal thread However - what we try to do here is really, matching the most natural (and sharp, non-distorted) widest field of view that a human eye can take in without rolling the eyeball around - while making the rim of the field disappear. It is the famous "floating in space effect" that only comes up in the brain when...
  • The CDK Optical Design

    CDK 20" Astrograph The CDK [Corrected Dall-Kirkham] telescope is based on a new optical design developed by Dave Rowe. The goal of the design is to make an affordable astrographic telescope with a large enough imaging plane to take advantage of the large format CCD cameras of today. Most telescope images degrade as you move off-axis from either coma, off-axis astigmatism, or field curvature. The CDK design suffers from none of these problems. The end result is a telescope which is free from off-axis coma, off-axis astigmatism, and curvature of field, yielding a perfectly flat field all the way out to the edge of a 52mm image circle. This means pinpoint stars from the center out to the corner of the field of view. The design is a simple and elegant solution to the problems posed above. The CDK consists of three components: an ellipsoidal primary mirror, a spherical secondary...

  • Why choose UFC Quickchange-Frontfilters with DSLR-Cameras?

    Info about using quickchange-frontfilters with the UFC in combination with DSLR-cameras There are no monochrome DSLR-cameras on the market, so a filter holder (e.g. the Baader-UFC) may seem quite useless for DSLR imaging, but if you take a closer look, there are indeed some interesting use-cases. Many owners of DSLR-cameras remove the complete UV/IR-blocking filter and use this simple way to improve the sensitivity especially for H-alpha – but because of the costs, they decide not to add a new blocking filter with increased H-alpha-transmission. But as a result, you have to find another way to block the IR- and UV-parts of the spectrum so that they will not decrease the image quality. You can use the UFC to mount such a UV/IR-cut filter in front of the camera - and to quickly replace it with another filter, without touching the camera. Narrowband filters are not perfectly suited for a...
  • New accessories for H-alpha solar observation / imaging

    A competely equipped M68 H-alpha Telescope - with all recommended accessories Our sun is a fascinating target even when the solar activity is low - given that the telescope aperture can be increased sufficiently. When equipped with a heated SolarSpectrum H-alpha filter, telescopes from 80mm aperture to 280 mm aperture will show incredibly faint, rapidly changing structures. A SolarSpectrum filter with matching D-ERF-filter and telecentric beam accessories will turn almost every telescope into a highest resolution H-α-telescope. These heated H-alpha filters are manufactured for observatories and ambitious amateurs who want to utilize the aperture and resolution of their existing large telescopes for detailed imaging and monitoring faintest solar features, instead of just taking a quick look at our closest star with a comparably small objective aperture. SolarSpectrum filters have no central obstruction and the whole H-alpha stack of optical elements inside is precision heated with a autocorrecting thermo-controller. There is...
  • Planewave CDK 20 First Light at College CFG Wuppertal/Germany

  • Baader-UFC (Universal Filter Changer) – the ever-growing filter chamber

    UFC 2" Filter slider (#2459112) with mounted Filter - showing both sides UFC D50.4mm Filter slider (#2459113) with mounted Filter - showing both sides Application Image: UFC 50x50 Filter slider (#2459114) with mounted Filter - showing both sides >> View all UFC-Products << The Baader-UFC is the priceworthy answer to an ever growing problem. New camera-models come to market in ever increasing speed. Spacers between telescope and camera don´t support the correct distance or are subjected to torsion due to their flimsy design and heavy cameras. And the owner may want to change the telescope - or use several OTAs, but does not want to purchase new filters and filter sliders all the time. The Baader-UFC is a (seemingly) simple answer to a complex problem. It is made in the typical Baader-way, trying to connect each and everything in the most elegant and flexure-free manner. The filter chamber (UFC-Base) is...
  • 30 years of Baader-Domes on Mt. Skinakas

    Baader 8m Dome in 2016. © Blinov Dmitri, http://robopol.org/gallery 30 years of Baader-domes on Mt. Skinakas, right next to the mythological birthplace of ZEUS Read the official letter by the Foundation for research and technology Heraklion, Crete September 27, 2016 The Observatory seeing conditions are excellent, with median seeing in two campaigns of 0.7 arcsec. There are two telescopes currently in operation at Skinakas Observatory: a 30 cm Schmidt-Cassegrain telescope (this was the first telescope installed at the Observatory in 1986) and a 1.3 m, modified Ritchey–Chrétien telescope (commissioned in 1997), which is the principal observing facility of the Observatory. Both telescopes are operated on a regular basis for research and educational purposes. There are currently over 190 publications in international refereed journals which present results from Skinakas observations. Baader-Planetarium has constructed domes for both telescopes. The domes have successfully withstood the extreme winter weather conditions on top of Skinakas...
  • Optical tube lengths of Clicklock mirror diagonal

    Recently we received the following questions on our 2" Clicklock Diagonal Mirror and wanted to answer including the below illustrations for other customers: According to image below is the optical path mentioned in technical data (112mm for #2956100 and 109mm for #2956100Z) measured along optical axis from point A to B or point A to C? what is the dimension from point B to C? Can 2” barrel (at point A) be removed from #2956100 and exchanged with another accessory (is it available?) to change the diagonal to #2956100Z (M68x1 thread)? Please note below our answer and adjusted graphic: The optical path of 112mm is measured A to C. The lightway from A to B would be ~71,5mm. Please note that the final endpoint of B is 3,5mm outside of the prism body (as illustrated in the below graphic), it looks just like point A in your drawing The Dimension from B...
