  • Perfect coma correction with Baader-MPCC – but how to adapt eyepieces?

    We received the following question and found it important to write an extensive answer for other customers. QUESTION: I purchased the Hyperion Zoom and the MPCC Mark III. Can you tell me how to adapt the eyepiece to the coma corrector? I also want to use other eyepieces. How do I know the right distance between fieldstop position and the MPCC? ANSWER: It is easy to produce an adjustable 1¼" eyepiece adapter for the Baader-MPCC coma corrector, offering a variable optical length from 49 to 64 mm, by using the following two parts: Baader focusing eyepiece clamp 1¼"/T-2 (item no. 2458125 / # 8a) Baader VariLock 20-29 mm T-2/T-2 adapter (item no. 2956929 / # 25Y) Combining these parts on top of the MPCC T-2-thread...
  • ClickLock 2" clamp for your telescope

    Dear Stargazer, Thank you for your interest in our ClickLock clamps. We are very pleased that you consider this clamp connection to be a worthwhile purchase for your telescope. We may not yet offer ClickLock clamping for your telescope system. However, we will try to produce more adapters in the future - but we always need the following information below. Thank you if you fill in the form below and send it to us. This will make it much easier for us to decide on the most popular adapter solutions. Unfortunately, we cannot yet make any concrete commitments regarding availability, but you can be sure that we would like to use our clamping device on as many telescopes as possible.

  • Implementation of UV/IR Cut Filter - Test Report

    Shooting the moon through a normal Baader UV/IR Cut Filter in comparison with the Baader IR Passfilter >>>> In the near infrared spectral range atmospheric disturbances (seeing conditions) are much more less than in the visible spectral range. Images taken in the near infrared light are often sharper than images taken in shorter wavelength. Special the moon (and the sun also) are nice targets shooting images with the IR Passfilter due to their brightness. All the following images was taken in the same night within a time interval of only 45 minutes (decreasing moon). The seeing was during the whole imaging session moderate. Image details: standard Celestron C14 in prime focus with a Celestron SkyRis camera 445 mono. Telescope location: Onjala Lodge/Namibia. Stacking each 144/1.200...
  • Dovetail-bars and -clamps - the “Missing Link” for your equipment

    Mounting accessories connect telescope and mount - be it for a permanent setup or to make quick changes from one instrument to the next possible. We can offer several bars and plates, so that you can adapt almost every telescope: Modell V (EQ) bars and clamps - for Vixen / Celestron / Sky-Watcher / Synta and many more. (Base width of the bar's prism: 44 mm. Bar width of the side facing the telescope: 70 mm) Modell Z bars and clamps - for Zeiss / Astro Physics (Base width of the bar's prism: 40 mm. Bar width of the side facing the telescope: 70 mm) Modell 3" bars and clamps - for Losmandy / Astro Physics (large) / Celestron (large) (Base width of the bar's prism: 76 mm, equals 3"....
  • Baader BBHS ® reflective properties

    Exclusively available on Baader Sitall Ceramic Mirrors and on selected Baader prism Star Diagonals: BBHS® reflection coatings predominantly are being utilised on our highest quality grade 2" BBHS® Sitall Stardiagonals (#2456115 – incl. black housing and 2" ClickLock clamp) as well as on the BBHS® T-2 Sitall Stardiagonal (#2456103) - where the housing features a male and female T-2 thread - for shortening the optical path with bino use, and to offer the utmost in adaptation variability as well as much more light throughput than with any conventional 1 1/4" star diagonal. BBHS® stands for Broad Band Hard Silver. When applied onto our Sitall (zero expansion glass-ceramics) substrates, these multiple deposited layers of hard silver are being sealed by a set of dielectric layers to...
  • Features of Baader Narrowband Filters

    A brief introduction to the function of narrowband filters. Narrowband filters have revolutionized CCD photography and now more and more image acquisition with CMOS cameras for the “amateur astronomer” in the past two decades in incredible ways. It was now possible for small telescopes, even in light polluted city areas, to photograph faint nebula – and generally the universe surrounding us in the incredible variety of coloured “gaseous areas” – without restriction of exposure times, and by combining the exposure of each colour of the various emission lines – even the faintest nebula were suddenly registered despite strong light-polluted skies. Suddenly, the smallest backyard telescope can collect the real light of gaseous nebula to produce image results there were otherwise only reserved for telescopes with...
  • The Baader Astro T-2 System™

    For over 30 years we have focused on the Astro T-2 thread system (M 42 x 0.75 mm); virtually every telescope manufacturer must offer this thread far ahead of the focal point of his instrument, such a universal T-ring (for DSLR cameras) can be connected. The only exceptions are (still) Russian equipment, there the thread diameter is the same, but the pitch is still 1mm per revolution - rather than 0.75mm! Therefore, we offer among other things a "Russians adapter". At only 7mm additional optical length it can allow so many Russian lenses or telescopes to be compatible with an international Astro T-2 (M 42 x 0.75mm) connector! For the sake of better recognition mostly are marked. See marking small 'a' or small 'i' in...
  • Observation: Minor planet Clausbaader (5658)

    From Dipl.-Ing. Wolfgang Paech – Onjala- and Chamäleon Observatory, Namibia For this year's longer stay in Namibia we planned to photograph the minor planet (5658) Clausbaader. It had a high altitude in the evening sky, close to Saturn. The series is intended as a small tribute to Mr. Claus Baader, the founder of Baader Planetarium in Mammendorf, who was one of the leading personalities in the field of amateur astronomy and public education in the last century in Germany. Read more under Company History. The images were captured at the 150mm Zeiss APQ refractor at Onjala Observatory and an "ancient" SBIG ST2000-XM. After completion of our "Project Pluto" - the experiment to take Pluto with a classic 2 inch telescope - first test images were...
  • Information about Baader Filters and Filtercells

    About Baader Filters The variety of uses for filters in amateur astronomy has considerably increased during the last decade, enabled by both more accurately manufactured optical accessories, and, above all, by the “digital revolution“. In the old days, colour filters for visual planetary observations were not screwed in the front part of the eyepiece, but were simply placed between the eyepiece and the eye. Plane-parallelism of these filter glasses was not important, because they were not in the optical path of the telescope. Today, filters are placed in the optical path of the telescope, even well in front of the focal plane. This definitely requires some degree of plane parallelism and accurate production of the filter glasses. Every single cell mounted filter delivered to our customers is cut as a round...
