  • M31 in only 4,5 hours

    THE STORY: An M31 that fell from the sky The Andromeda galaxy is an object seen by every amateur astronomer, either with own eyes or as an image. I was particularly fascinated to image our magnificent neighboring galaxy with the RASA 8" - Rowe-Ackermann Schmidt Astrograph (#822252, € 2195,-) under a perfectly dark sky. This was one of the reasons why my way led me to La Palma for one week in October 2019, to do my images at the Athos Centro Astronómico (www.athos.org). The QHY 163M camera is a perfect fit on the RASA 8" in terms of field size and pixel scale for M31. For a monochrome camera, the Baader FCCT (Filter Changer Camera Tilter) for RASA 8" and QHY cameras (various versions available) (see...
  • QHY 5-III-678M vs. QHY 5-III 178M: Key Enhancements and Differences

    Luc Cathala made a comparison between QHY 5-III-678M CMOS Camera (#1931036 , € 410,-) and the QHY 5-III-178M.The QHY 5-III-678 M/C can be considered as an improved version of its earlier QHY 5-III 178M. Like the Sony IMX 178, Sony's new IMX 678 sensor is a 1/1.8-inch back illuminated (BSI) sensor. However, compared to the IMX 178, it has higher resolution (smaller pixels) and higher QE, as well as increased sensitivity in the near-infrared (NIR) spectral range. In addition, the QHY 5-III-678 M/C camera modules have some improved features. Review by Luc Cathala: Since I was a child, the night sky has always fascinated me. I bought astronomy magazines from time to time. In mid-December 2002 a friend lent me his Celestron 6. That night...
  • Baader Photometric Filters: Dark nebulae appear in a new light

    Combination of photometric and RGB filters to highlight dark nebulae Photographing dark nebulae is a fascinating challenge for astrophotographers, often posing difficulties due to the low brightness and high contrast between celestial objects and dark nebulae. This often requires the use of different techniques and exceptionally dark skies to bring out fine details in the dark nebular structures. In this test report, we examine the photographic results and the effectiveness of the combination Baader SLOAN/SDSS (ugriz') Filter Set – photometric Baader SLOAN/SDSS (ugriz') Filter Set – photometric (various versions available) und Baader RGB Filter Set – CMOS-optimized (various versions available) to evaluate its effectiveness in improving contrast and detail, as well as enhancing them in all their colorful glory, while maintaining natural color reproduction.

  • From Relic to Modern Observatory: The Story of my "Antique" Baader Dome

    Note from Baader Planetarium: The following article was kindly provided to us by Christoph B. for publication. Discover this 2.1M Classic Slit Dome also on our World Map Background My journey to establishing my own observatory began with an extraordinary heirloom, a Baader observatory dome over 30 years old, carrying its own remarkable history. This dome had been in the possession of Mr. Ernst Blättler (✝) for decades, who had donated it to his club, the Astronomical Society of Zürcher Oberland (AGZO), some years ago. Until his old age, he was active as a passionate demonstrator. A few years ago, however, the club expressed the desire to operate a modern dome with the latest technology, which could be remotely operated by the club members. Therefore,...
  • MaxBright® II Binoviewer at the Takahashi Mewlon

    Notice: Trying to get property of non-object in /home/baadercom/public_html/blogs/wp-content/themes/fishpig/local.php on line 458 Takahashi is known for excellent telescopes, but when it comes to adapting accessories, they sometimes go their own way, which can make life hard for astronomers. In particular, the use of a bino viewer on the Takahashi Mewlon kept raising questions, and since we don't sell Takahashi telescopes, we couldn't simply try it out ourselves. Baader MaxBright® II Binoviewer Thus, we are all the more grateful to our customer Maiko, who was able to successfully use the Baader MaxBright® II Binoviewer with case (#2456460 , € 479,-) with his Mewlon 180 C and gave us feedback on his setup. We thank him for the information and would like to briefly present the required...
  • Baader CMOS Optimized Filters: Unleashing the Full Potential of Astrophotography

    What do you look for in an astronomical filter? Everyone has different requirements and goals and with a myriad of filters available today; how do you choose the right filters to unleash the full potential of Astrophotography? In this blog our customer Ian Aiken gives some high level advice on what to look for when choosing a filter, coupled with reasoning why he choose the Baader's CMOS-Optimized LRGB and Ultra Narrowband f/2 filters, along with example LRGB and SHO images taken with these filters on his Celestron RASA 11 from his Bortle 7 suburban location. New CMOS-optimized Baader filters Blog Post by Ian Aiken: I live in the North East of England in the United Kingdom, which experiences a temperate maritime climate characterized by mild...
  • The Baader Planetarium UFC Design-Guide

    The Universal Filter Changer (UFC) system with its solid mechanics and high flexibility has found a large user base worldwide. Nevertheless, there are always applications that are not covered by the adapters available to date. Therefore, we receive requests for technical drawings from our customers again and again. In the course of further development of our products, we are now pleased to be able to provide the UFC Design Guide. This design guide contains technical drawings with all the relevant dimensions you need to make your own adapters for both sides of the UFC - be it S70 ring dovetail connection on the telescope- side or the eyepiece/camera-side adaptation: UFC Design-Guide: Camera-side UFC adapterDownload as PDF UFC Design-Guide: Telescope-side UFC adapterDownload as PDF This means...
  • Field report: „Baader SunDancer II Telecentric System TZ-4S“

    Notice: Trying to get property of non-object in /home/baadercom/public_html/blogs/wp-content/themes/fishpig/local.php on line 458 This summer we provided our customer Mr. Rüdiger Proske with the new Baader SunDancer II Telecentric System TZ-4S (#1363080 , € 385,-) for a comparison test with the longer TZ-4. Most interesting was the question how the TZ-4S, which was primarily designed for the SunDancer II H-alpha filter, harmonizes with his large SolarSpectrum H-alpha filter. We are very happy about his very positive conclusion and his field report. Please read the detailed report of Mr. Rüdiger Proske here: In June 2023 I was offered the opportunity to test the new "Baader SunDancer II Telecentric System TZ-4S" (short TZ-4S) for the upcoming market launch. Since I had already been working with the classic, long...

  • QHY Cameras for Spectroscopy

      Special feature QHY294:  The QHY294M is technically a special case and is supplied by Sony with a fixed pixel binning of a 2x2 matrix as standard. As a result, the Back Side Illuminated Sensor delivers 11.7 megapixels at 4.63 µm and 14-bit data depth in standard mode (readout mode 0). QHY has managed to switch Sony's "on-chip" binning on and off in the monochrome version of the 294 PRO, thereby enabling two different readout modes. Readout mode 1 "unlocks" the binning to produce 46.8 MP images with 2.315 µm pixel size at 12-bit data depth per pixel. The ability to trigger the 294 PRO with two different pixel sizes also allows it to be used for two different imaging focal lengths to match the...
