  • Bilderbericht zu 2.6m Baader Classic Dome (ECO-version) Privatsternwarte

    Herzlichen Dank für den Bau und die Installation der Kuppel! Wie Sie auf den Bilder sehen können herrschte beim Bau der Sternwarte ein perfekter Altweibersommer. Die Gaube wurde von meinem Dachdecker termingerecht in nur drei Tagen errichtet. Die gesamte Konstruktion (Dachgaube, die Wände und die Kuppel) sind auf einem neuen Balken, im Dachstuhl und den in den tragenden Wänden eingehängt und übertragen keine Kräfte auf die Betonplatte, die auf 9cm starken Styrodur-Platten schwimmt. First Light Das First Light ist ein Standard-Objekt, welches aus meiner alten Sternwarte für mich bisher nicht erreichbar war. Der Pelikan-Nebel als GIF-Animation zeigt hier die verschiedenen Phasen der Bildbearbeitung https://www.astrobin.com/323856/ [br] Die Vorbereitungen [br] Der Kuppel-Aufbau Die Baader-Mannschaft hat sehr flexibel auf die sich verschlechternde Wettervorhersage reagiert und ist am Donnerstag den 26.OKT bereits um 6Uhr Früh angereist. An diesem sonnigen Tag wurde die Kuppel aufgebaut, der Kran hat die Säule und die Montierung an ihre...
  • M45 - the Plejades taken with Baader APO and GM 1000 HPS

    The following image of the Pleiades (M45), which our customer Christoph Kaltseis has achieved with the Baader APO Travel Companion and the 10 Micron GM1000HPS on La Palma (Athos Campus), is a special treat regarding image detail and star rendition. Partically interesting is the Nikon D810A camera with a 36x24mm sensor and 4.87my pixels. Its sensational resolution will show any aberations in the optical system straight to the edges mercilessly. Most CCD cameras either have smaller sensors or much larger pixels, which helps to camouflage optical deficiencies. Not to speak of bad seeing... Image editing / sharpening was done with the APF-R Method. Due to the good optical quality of Baader APO,  airy discs with 5 micron diameter where archieved – not to mention the excellent tracking of the GM 1000 HPS mount and the brilliant location (observation site).
  • My spectra show dark stripes (see mark in picture) - where do they come from?

    Dark horizontal streaks or stripes in the spectrum are caused by dust deposits on the slit plate of the spectrograph. A partial attenuation of the spectrum results from dust spots (“Donuts”) on the camera sensor. Let's start with the slit plate of the spectrograph. A dust grain deposited on the slit becomes apparent across the spectrum as a horizontal, dark line perpendicular to the spectral lines. The more frequently the DADOS is attached to the telescope, the more dust can penetrate. And dust can also penetrate through the 1 1/4 " nosepiece of the slit viewer when changing the guide camera. Cleaning is critical and not recommended because wiping on the slit plate would cause serious harm. Gently blow away dust from the slit plate with DRY compressed air, being careful not to let any liquid propellant from the compressed air get onto the slit plate. Never blow on the...

  • APF-R : Absolute Point of Focus

    What is APF-R The image-sharpening process APF-R was designed and implemented by Christoph Kaltseis over the last years. The basis is a simple, but important question: What does a really sharp picture look like? APF-R delineates this step in image processing in a new way. Numerous processes claim to master this topic, but in all cases, compromises have to be made. Each image is dependent on numerous factors, especially in astrophotography. Christoph Kaltseis' motivation was to get the maximum out of each picture. On the way to an APF-R picture, it is important to make the first step as thorough as possible. This first step is crucial: It determines what details will be visible in the final image.[br] Please note: The images shown on this page are low-resolution GIF-images, which should only demonstrate the sharpening effects. Original images as .PSD files can be found on www.cedic.at/apfr. Visual Components: Sharpness is...

  • Team Baader at the "Great American Eclipse" 2017

    For years our colleagues Martin Rietze and Michael Risch have been hunting for the next solar eclipse in the most remote places in the world. See e.g. our blog posts on AstroSolar.com: 2015: Solar Eclipse Adventure in Svalbard Martin Rietze and Michael Risch from Baader Planetarium – both solar eclipse chasers – have again traveled to the event and brought us impressive images and videos. Svalbard is one of the few islands where the path of totality on March 20th, 2015 crossed land. Its 1300km from North Pole Our chances for good weather were somewhere around 50% so it was more or less gambling flying there to see the Total Solar Eclipse...

  • Concerning fear about counterfeit Baader AstroSolar Viewers and Film coming up in the USA

    Don't miss out to read customers comments and our detailed replies below.[br] Update August 17th, 2017: Quote below from news article AAS spokesman on Amazon recall, fake products, safe eclipse viewing Amazon screwed up. I've been telling them that for weeks and as the problem gets worse, the person there stopped responding to me. I think they're overwhelmed. They know they screwed up. They're trying to do the best they can. They don't know what they're doing. Dr. Rick Fienberg – American Astronomical Society (AAS) press secretary Regarding Solar Viewer AstroSolar® Silver/Gold Baader Solar Viewer AstroSolar® Silver/Gold are CE / ISO certified and absolutely safe: they conform to and even exceed the transmission requirements DIN 12312-2:2015 for eye safety On Sat, Aug 12, Amazon sent an email to all customers who had purchased a wide variety of solar products (glasses or viewing cards) from several of our US-dealers that the...
  • Off-standard single filter sizes from Baader - why not:

    Quite often we receive requests for a single filter in an off-standard size. In all cases we are sorry that we must answer as follows: Sorry (we know it would be so very much cheaper in production - and we would be so much more flexible to fill special requests) - but we have decided long ago to not cut or saw our filters from large plates because this would leave the coating stack open and mutilated (with microscopic cracks) all around, prone to aging and peeling. Many times we had the chance to inspect our competitors filters after several years of use (due to our 30+years of servicing SBIG-CCD-cameras/and filter wheels) and we realized already 15 years ago how moisture and heat stress can deteriorate even most modern hard coatings, slowly peeling off from the carrying substrate over time, unless the coating stack is sealed all around the filter...
