  • Detailed Customer Review on CDK 17" PlaneWave Astrograph

    Dear Mr. Baader, I am happy to comply with your request and share with you my criteria that led to the purchase of the 17 inch telescope from  Planewave, and following my experience with this telescope. Since this was a rather complex topic, please forgive the long text and its extent , which certainly clearly exceeds a "normal" customer judgment. Download: detailed review on CDK 17" PlaneWave Astrograph (pdf-file) Decision criterions for the choice of the Planewave astrograph were primarily: "First Light" at full focal length of the PlaneWave. Exposure 40x30 seconds (without any guiding) was added, taken with a modified Canon EOS 40 DA. robust mechanical construction of the whole telescope, fixed installation and collimation of primary mirror and field corrector at factory, stable secondary mirrorcell, easy adjustment of the secondary mirror, easy control of distance between the main and secondary mirror withRonchi test, good focus stability with slight...

  • 17.5mm Morpheus® Review

    William "Bill" Paolini has been actively involved in optics and amateur astronomy for more than 50 years, and is author of the popular book: Choosing and Using Astronomical Eyepieces We appreciate the positive feedback we have received so far. With 3 years of additional development time - the Morpheus 17.5mm was also the most elaborate eyepiece project we had ever started. A detailed Morpheus 17.5mm test report has now been published by William Paolini in the most popular astro forums. We are very happy about his extremely positive conclusion and would like to quote the following line: The latest Baader addition to the Morpheus eyepiece line up comes across to my eye like they saved the best for last. In general the comments on the Morpheus 17.5 and the improvements to the complete eyepiece series (new eyecups with integrated metal threaded ring, index clip, etc.) in the popular forums are...
  • 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...
  • Astro-Physics – High-end German Equatorial Mounts

    HIGH-QUALITY PROFESSIONAL ASTRONOMICAL MOUNTS Astro-Physics 130mm/ f/6.3 StarFire GTX Refractor "Gran Turismo" Keeping to the same quality standards that have made the fully-apochromatic refractors legendary, Roland Christen's company has been building German Equatorial GoTo mounts for more than three decades. Their proven stability, accuracy and durability is the reward for anyone who can endure the traditionally long delivery times. "El Capitano" at Dome C of the Concordia Station in Antarctica" Two "el Capitan" mounts are working in the Antarctic for several years now, even at temperatures of -75°C. They are perhaps the most spectacular example of the durability of the sturdy Astro-Physics mounts and are representative for many more exemplars that often run for decades at our customers without failures. Astro-Physics GTO 1600 With a very accurate manufactured worm gear the Astro-Physics mounts are equally well-suited for smooth, effortless tracking of celestial objects as well as for all visual and...
  • 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...
  • 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...

  • An experience report on the new Baader Telecentric System TZ-3 and the Research Grade (RG) Telecom­pressor (TC) 0.4

    An experience and observation report on the new Baader Telecentric System TZ-3 and the Research Grade (RG) Telecom­pressor (TC) 0.4 for solar observation in the H-alpha light with SolarSpectrum filters download the complete review (pdf) Introduction Successful H-alpha-observations of the sun with narrow-band line filters from the manufacturers   “SolarSpectrum” and / or "DayStar" require an almost parallel beam of light with a focal ratio of approx. f/30 directly in front of the filter, otherwise the filter will not work properly. This is not so easy with today's fast optical systems, which work around f/7. Such an opening ratio can be achieved either by masking (reducing) the front lens opening or by parallizing the optical beam with a "telecentric system" (TZ). * TZ: See also the supplement at the end of the report. My "solar telescope" is an AstroPhysics refractor with an aperture of 155mm and a focal length of 1.085mm,...
