    New Baader f/3 Ultra-Highspeed Filter-Category 3.5 nm / 4 nm In addition to a lot of positive feedback after the introduction of our new CMOS-optimized filter families, however, there were also complaints about insufficient signal and resulting halos. After a thorough examination of the situation, we have now been able to identify and narrow down the problem. We have used the last few weeks to explain the requirements for the Preshift of Highspeed-Filters for the first time in form of a detailed, 24-page White Paper (at the moment in German only), and we have re-categorized all Ultra-Highspeed narrowband filters, so that you can more easily identify the right filters. The previous 3.5 / 4nm Ultra-Highspeed filters (which were advertised as having an operating range of...
  • Preshift and further information concerning Baader CMOS Filters

    During the last couple of months after introducing our new CMOS-optimized filter families, we have received lots of positive feedback from our customers. However, there was an increasing number of reports and long discussions about low signal, halo strength and so on, which showed more and more, that the complexity of this topic needs a really detailed explanation. Especially when going to the physical limits, like with our Ultra-Narrowband (UNB) filters, there is no standard solution for every user with different telescopes, sky and weather conditions This situation was intensified because the f/2 Ultra-Highspeed filter category especially needs a more selective categorization, in order to select filters with the correct PRESHIFT, to comply with the f/ratio and the amount of obstruction of the respective telescope...
  • Product annoucement: QHY533 M/C CMOS camera

    We at Baader Planetarium consider the QHY 533 M/C to be a very good and reasonably priced entry-level camera. It has everything a modern CMOS camera can do. For amateur astronomers interested in all areas of astronomical photography, the QHY 533 C/M can cover a wide range of your images. With its BSI Sony sensor, the camera is extremely sensitive and low-noise in the deep sky range. Thanks to the good cooling performance, long exposure times can be realized with it. The pixel size of 3.76 x 3.76 µm is optimally adapted for shorter focal lengths of 500 to 750 mm. Optimal for RASA and Hyperstar telescopes. Canon and Nikon telephoto lenses are also adaptable with a required backfocus of 55 mm. Due to the...
  • Swapping between eyepieces: The useful Baader Q-Turret Four Eyepiece Revolver

    The planets Saturn, Mars, Venus and Jupiter are making an appearance in our morning sky making a lovely photogenic celestial lineup. About an hour before sunrise you can see the magnificent ringed gas-giant planet, and second largest planet in our Solar System, Saturn towards the south east with our red coloured neighbour Mars sitting below and to the east of it. Venus is next in line shining brightly at magnitude ~4.2 and is exhibiting a gibbous phase and very low near the eastern horizon is the largest planet Jupiter. These planets will make their way to being evening objects later in the year becoming better positioned where they will be observable for longer. Our Moon is easily seen throughout most of each month so its...
  • Free Download: 3d-printed flip mirror adapter and holder

    Free Download: 3d-printed FlipMirror II Mirror Holder Update: We are pleased that the Baader FlipMirror II Star Diagonal (#2458055, € 215,-) is so well received and inspires some customers to dream about what else would be possible. Since we ourselves cannot realize all the different constellations from partially transparent to dichroic mirrors, we have decided to publish the mirror holders that we install in the FlipMirror II. This way, our customers and users can 3D print the holders themselves and then try out any mirror type and shape. We are looking forward to your results and experience reports! Below is the download link (which will only work when you're logged in). Please also note the information below about the Creative Commons License. The file is...
  • A Brief Overview of the Baader Tilter Family

    If you notice that the edges of your image(s) are not sharp then image tilt may be present in your system. Image tilt is caused when the sensor is not perpendicular to the light path. The cause(s) of image tilt can be many and can include flattener/corrector lenses, tilted focuser drawtube, extension adaptors, camera angle adjusters as well as inherent camera sensor tilt in the camera body itself. Being able to correct for this image plane tilt is important and essential to get perfect focused sharp star images across the field of view. Baader Planetarium currently offer three accessories - their "Tilter family" - that can help compensate for image plane tilt. Baader UFC-Tilter (#2459146, € 260,-) :  an S70 dovetail accessory that fits on...
  • Baader Planetarium at the 2022 Practical Astronomy Show (UK)

    At 9am on Saturday 19th March the doors opened at the Kettering Conference Centre to welcome a long queue of visitors which had formed to attend the 2022 UK Practical Astronomy Show (PAS). This was the second time that this event has been run since its first outing 2019. Originally planned to be yearly, the event had to be postponed in 2020 and 2021 due to the pandemic. This event would be the first astronomy show in the UK since COVID. I attended PAS representing Baader Planetarium with a small stand. Preparation for PAS had started several weeks beforehand with a shortlist of display and demonstration products and associated information leaflets and a new pull-up banner. Due to a foot injury my wife had to...

  • Installation of a 4.2m Highspeed Dome on Teide/Tenerife

    Our installation team had the task of installing one of our HighSpeed domes on the Teide in Tenerife in May 2021. The Teide is a unique natural wonder. The 3,715-metre high "sleeping" volcano is the highest peak in Spain. The national park located on the mountain is a UNESCO World Heritage Site and offers an impressive crater landscape with cooled lava flows and other volcanic phenomena as well as endemic animal and plant species. At an altitude of almost 2,400 metres, there are many astronomical observatories, including – due to the excellent seeing during the day – one of the largest solar telescopes in the world. Discover the 4.2M Highspeed Dome also on our observatory world map Our team was accommodated in the "Astronomers' Hotel"...
  • First light for SSC's satellite tracking ground station

    In collaboration with Baader Planetarium, Planewave and Andor, the Swedish Space Cooperation (SSC) SSC has been developing a ground station for satellite tracking over the past 1,5 years. A couple of days ago, a first successful test run took place at Baader Planetarium's factory. The development is part of SSC’s Space Situational Awareness (SSA) program with the aim at contributing to both safer and more sustainable use of near-Earth space, as the number of objects keeps increasing at a rapid pace. The aim of the tests was to ensure the station to be as efficient as possible in generating highly sophisticated SSA data, by combining the highest quality individual components. A 3.5m Allsky Dome from Baader Planetarium was chosen as the protective structure. This Dome...
