  • 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...
  • 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...

  • New QHY 5 III series of planetary and guiding cameras

      Update 05/2023: New OHY Planetary- and Guiding Camera QHY 5 III 678 M/C The QHY 5 III 678 M/C is the latest evolution of version 2 of the QHY 5III series of planetary and guiding cameras. The QHY 5 III 678 M/C can be considered an improved version of its predecessor, the QHY 5-III-178M CMOS Camera (#1931024 , € 375,-) . Like the Sony IMX 178, the new IMX 678 sensor from Sony is a back illuminated (BSI) sensor in 1/1.8 inch format. However, compared to the IMX 178, it has a higher resolution (smaller pixels) and a higher QE, as well as increased sensitivity in the near infrared spectral range (NIR). In addition, the QHY 5 III 678 M/C camera modules has the...
  • A comparison of the technical data between the Sony CMOS sensor IMX 461 and the Kodak CCD KAF 16803 sensor - CMOS vs.CCD

    Introduction For several decades monochrome CCD sensors were THE choice for astronomical image acquisition, be it for imaging, astrometric or photometric applications. At the beginning of the technical development, CCD sensors were much smaller in area than the standard 24 x 35 mm format, but they were much more sensitive and did not suffer from the reciprocity error (the black screen effect), a classical problem of all standard film emulsions. However, CCD sensors were very expensive - initially reserved for professional astronomy - and it took some time before 35mm-sized sensors were available at prices that amateurs could afford. In addition, the pixel dimensions were large (9 µm and larger) and thus hardly usable for short focal length imaging optics. In the meantime, telescope optics...
  • First Impression of the new Baader Calcium-Filter

    In the spring of 2022, I had the chance to give my opinion on a couple of prototypes of a possible successor to the K-Line filter. The calcium line (CaK) was the only part of the solar spectrum that I had not yet covered with my solar setup. This absorption line is indeed somewhat exotic, and the required filters are not very widely distributed. The familiar sight of the white-light (continuum) Sun through a Herschel prism or astrosolar film is probably well-known to everyone who has ever tried solar observation. White light is the cheapest and easiest part of observing the sun - in the simplest case, this can even be done by projection as with the . I have used this part of solar...
  • The eyepiece series from Baader Planetarium

      The eyepiece is half the optics - and every telescope is only as good as its weakest link. That is why Baader Planetarium not only offers high-quality star diagonal mirrors and prisms (which we present in this PDF), but also several series of eyepieces. Each has its own special features, which we would like to present to you briefly here. Besides, they are firmly integrated into the Baader accessories programme and offer interesting solutions for eyepiece projection and binocular observation. The series at a glance   Classic Hyperion® Morpheus® Ortho/Plössl Aspheric Modular Zoom Focal length 6 / 10 / 18 / 32 31 / 36  5 / 8 / 10 / 13 / 17 / 21 / 24 8-24 (with Barlow 3,6-10,7) 4,5 /...
  • Test Report: Baader Solar Continuum Filter revisited – now with 7,5nm FWHM

    Sometimes it is worth giving things a second chance after many years. Panta rhei, as the saying goes… The Baader Solar Continuum Filter is such an inconspicuous thing that I had largely ignored after a first quick test 15 years ago and which has now completely convinced me in its current incarnation with 7.5nm FWHM: Baader 7.5nm Solar Continuum Filter (540nm) Baader 7.5nm Solar Continuum Filter (540nm) (various versions available) . This is due both to my observing experience and to product development and a larger variety of telescopes now in my reach. Spoiler: Correctly used, it has got an incredible potential – not only to remove the colour aberrations of achromatic lens telescopes as expected, but to my great surprise also when imaging the...
  • WHY are the QHY600 CMOS cameras more expensive than models from other manufacturers

    WHY are the QHY600 monochrome CMOS cameras more expensive than models from other manufacturers that also use the Sony IMX 455 BSI CMOS sensor? The image sensor - the heart of EVERY astronomical CMOS camera Image sensors are THE basis of ALL imaging in astronomical photography. The performance of the camera - i.e. the read out raw image after exposure - is based on the quality of the CMOS or CCD sensor and its performance. Image sensors of many manufacturers are produced in different qualities: In very high quantities the "consumer-grade" sensors and in much lower quantities - and therefore much more expensive - the "industry-grade" sensors, which have to pass more extensive and tougher quality controls before delivery. The monochrome "Industrial-grade" IMX 455 sensor...
  • EMCCD vs sCMOS Cameras | A Comparison (Post by Andor Technology)

    sCMOS technology is unique in its ability to overcome many of the mutual exclusivities that have marred other scientific detector technologies, resulting in an imaging detector that simultaneously optimizes a range of important performance parameters whilst maintaining Snapshot exposure capability.
