Modern meets antique: 3.5M AllSky dome in a Greek mountain village
This entry was posted on January 8, 2020 Last modified on February 26, 2024.
Our last dome assembly in 2019 took place in the second week of December in Greece. Since this installation had a special flair as well as bad luck and breakdowns, we would like to share with you the following report of the installation. After the dome has been used for some time, we will also ask the customer if he agrees that his dome will appear on our observatory world map. The mountains of the Greek peninsula Peloponnes are ideal for astronomical observations. Here an amateur astronomer has found an ideal place to realize his dream. The dome sits on a renovated 19th century house in an old, lonely mountain village at an altitude of almost 900m with an unobstructed view over the sea. However,...

HALOS – viewed without prejudice
This entry was posted on December 19, 2019 Last modified on February 26, 2024.
The moment you insert any type of filter into the optical setup, which consists of your specific camera, the appropriate flattener/reducer or coma corrector and the telescope, the filter becomes part of this unique optical system. And every optical system is different because many products from different manufacturers are involved. All optical surfaces interact with each other in some way. One possibility is that coatings of the camera reflect unwanted light back into the telescope and onto all optical elements in front of the filter. If there is no other optical surface that will reflect the light back to the filter a second time, then it is perfect. There are no halos other than residual halos or scattering, which are unavoidable, depending on the filter...

25th anniversary of TEC - Apochromats of the top class
This entry was posted on December 12, 2019 Last modified on February 28, 2024.
The "Telescope Engeneering Company" has long earned a reputation as a top-class telescope manufacturer. The family business in the US state of Colorado has been manufacturing telescopes of the highest quality in small series since the 1990s. Before TEC manufactured the first refractors in the year 2000 (regular production of APO140 started in 2002), TEC were offering Sitall mirror sets from LOMO (upto 1.4m) and MAKs from 150mm to 300mm. The distribution of these products is stopped. The three Petrunins are based on class instead of mass, therefore the delivery times are long! But the quality is also outstanding: TEC is one of the few manufacturers in the world that still masters durable oil-spaced triplet lenses. This results in particularly robust and stable optics that cool...

ON Semiconductor: CCD Retirement
This entry was posted on November 11, 2019 Last modified on February 28, 2024.
If you are considering a CCD camera using an ON Semi sensor, please act NOW. As many have heard by now, ON Semiconductor has decided to quit the CCD business. ON Semiconductor acquired the Kodak CCD product line and factory from Truesense about five years ago. All orders for ON Semi CCDs must placed by March, 2020. CCD Cameras from SBIG and FLI SBIG and Diffraction Limits are working to ensure a supply of popular ON Semi CCD sensors sufficient for our needs in 2020. However, there will be some camera price increases as ON Semi has also raised their sensor prices. Currently SBIG does not change the pricing of their highest-volume CCD cameras, but that will change as we consume the supply of...

Baader Observatories Map - Discover our Domes
This entry was posted on November 6, 2019 Last modified on February 19, 2024.
In 2019 we reported little about our observatory installations, instead we worked on an observatory world map. It shows not all, but many of the hundreds of observatories and domes we have installed over the last 50 years. This world map will continue to be extended with new and partly even more old observatory installations. Please note: Most of the content was filled in by our customers themselves. For this reason we ask for your understanding that this content is mostly written in german language only (indicated with a german flag next to the title). On our observatory world map you can see with many pictures and information all installations, which we may present - divided into the categories Private Observatories, Research and Education, und...

2,6m private classic dome in Switzerland with GM2000 QCI
This entry was posted on December 18, 2013 Last modified on February 28, 2024.
This post has not yet been translated to english, we apologize. In the meantime until we get to it, please use Google Translate or a similar tool. Thank you for your understanding. Kundenurteil von Josef Bucher Der Wunsch, eine eigene Sternwarte irgendwo auf dem Lande draussen unter einem wenig lichtverschmutzten Himmel zu haben ist bestimmt der Wunsch vieler Amateurastronomen. Seien wir ehrlich: Das Suchen nach gut erreichbaren und geeigneten Beobachtungsplätzen, der stets wiederkehrende Auf- und Abbau der sperrigen Instrumente, buntes Kabelwirrwarr auf dem Boden, leere Akkus und PCs auf wackeligen Campingtischen ist nicht jedermanns Sache. Vom Winde, der einem um die Ohren pfeift, dem Taubeschlag auf Tuben und Okularen und dem Frieren in der kalten Jahreszeit ganz zu schweigen. Mir erging es jedenfalls so. Aber...

Baader Universal Filter Changer (UFC): Simple photographic use example (Part 7)
This entry was posted on August 1, 2019 Last modified on February 27, 2024.
Photographic Use Example: We've been asked a few times recently on how to set up the Baader UFC for use with a DSLR and a range of wide-field imaging refracting telescopes. So we thought we would write a short blog on some ways this can be done. Let us start from the telescope side first. All the enquiries we have had, the wide field refractors have 2" barrel focusers, so there is our starting point. The telescope side of the UFC Base (to which everything else in the UFC system is connected to) uses Baader's S70 dovetail adaptors to allow the UFC to fit to telescopes. Looking at the UFC main diagram above Baader do a Baader UFC S70 / 2" SC-thread (f) Telescope-Adapter (optical height:...

Don't miss it: Transit of Mercury on November 11th, 2019!
This entry was posted on October 14, 2019 Last modified on February 28, 2024.
Transit of Mercury LIVE: NASA is broadcasting the film sequences of the solar satellite SDO for all those who cannot observe the Transit of Mercury on November 11th 2019. The films will be available on https://mercurytransit.gsfc.nasa.gov almost in real time: Starting around 1200 UTC (7:00 am ET) November 11, 2019, we will begin watching Mercury move into view against the corona of the Sun. This is about 45 minutes before it is visible against the Sun from the ground. We have created https://mercurytransit.gsfc.nasa.gov to let you watch this transit as short movies in almost real time. The transit lasts a little over 5.5 hours, ending as Mercury leaves the disk of the Sun about 1806 UTC but continues moving out through the corona for another...

Baader Universal Filter Changer (UFC): Visual use example (Part 6)
This entry was posted on June 26, 2019 Last modified on February 27, 2024.
Visual Use Example: Now that we have covered the main overview of the Baader UFC system in our previous blogs (parts 1-to-5), we thought it would be appropriate to give some examples of how the UFC system can be used. Firstly, this is not meant to be exhaustive as there are many combinations of telescopes and accessories. In this blog, we will consider an example of the UFC being used visually. One of the simplest ways of using the UFC visually is with 1.25"/2" eyepieces and with a suitable telescope that uses a 1.25"/2" focuser (or 2" focuser with 1.25" adaptor). If we go back to our first blog (Overview of the UFC system), we said that although the UFC system looks complicated, its actually...
