  • ISS Solar Transit with AstroSolar Photo Film

    AstroSolar® Photo Film OD 3.8 On April 14th, Philipp Salzgeber was able to catch the ISS while passing in front of the sun. For this, he used a filter made from AstroSolar® Photo Film OD 3.8 (#2459278) He kindly gave us the permission to repost his blog post from http://www.salzgeber.at/astrophotography/solar/iss-solar-transit. As the ISS orbits our planet, from time to time it passes in front of the sun for a given location. https://www.calsky.com and https://transit-finder.com/ allow you to predict such transits for your location. A combination of all frames that captured the ISS. On Saturday, April 14th 2018, such a transit happened, and I was able to capture it: (Of course the sound is artificial!) I used a 127mm refractor with a 2x teleconverter, shooting FullHD Video in DX crop mode on a Nikon D750.[br] Here are some images taken from the video, and a combination of all frames that captured...

  • Detailed Customer Review on CDK 17" PlaneWave Astrograph

    Dear Mr. Baader, I am happy to comply with your request and share with you my criteria that led to the purchase of the 17 inch telescope from  Planewave, and following my experience with this telescope. Since this was a rather complex topic, please forgive the long text and its extent , which certainly clearly exceeds a "normal" customer judgment. Download: detailed review on CDK 17" PlaneWave Astrograph (pdf-file) Decision criterions for the choice of the Planewave astrograph were primarily: "First Light" at full focal length of the PlaneWave. Exposure 40x30 seconds (without any guiding) was added, taken with a modified Canon EOS 40 DA. robust mechanical construction of the whole telescope, fixed installation and collimation of primary mirror and field corrector at factory, stable secondary mirrorcell, easy adjustment of the secondary mirror, easy control of distance between the main and secondary mirror withRonchi test, good focus stability with slight...
  • NEW: M-Uno Dual Single Fork Equatorial Mount from Avalon Instruments

    AVALON M-Uno Dual Coming with the same RA mechanics and Fast Reverse, Belt driven System, is an upgraded version of the well known M-Uno mount. The innovation on the M-Uno Dual mount is the new fully rotating Declination axis, which allows the use a second clamp (optional) to hold a second smaller OTA or X-Guider (optional). Either a standard or adjustable version of the GP & Losm. 3” clamps can be easily attached to the declination axis. Both the adjustable clamps are provided with inox screws to align a second scope (of smaller size compared to the main one used) in order to have both perfectly aligned to the same object or field of view. As an alternative, also the X-Guider accessory can be attached directly to the declination axis end as it provides a fine alignment of the guide scope itself. The use of a second scope on the...
  • Alt 7 Mount with AVALON StarGo Retrofit GoTo System

    Mr. Dal Sasso from Avalon Instruments and Mr. Quarra from Unitron The mounts by ALT are solid "workhorses", some of them are in use on observatories for decades. To modernise them - and to see if it is possible - we asked AVALON Instruments to adapt their up-to-date StarGo control to an ALT-7. The first results are promising. The Avalon control system is now working fine with the ALT mechanics, and the telescope can move much faster than before. But it wasn't easy: The stepper motors had to be replaced, the housing had to be modified and a gear box had to be designed to transmit the necessary force. So far and in the lab, everything works fine. We still have to make the final tests under the stars! We will let you know when there are news. Full video showing a 180 ° slewing of the mount with the...

  • 17.5mm Morpheus® Review

    William "Bill" Paolini has been actively involved in optics and amateur astronomy for more than 50 years, and is author of the popular book: Choosing and Using Astronomical Eyepieces We appreciate the positive feedback we have received so far. With 3 years of additional development time - the Morpheus 17.5mm was also the most elaborate eyepiece project we had ever started. A detailed Morpheus 17.5mm test report has now been published by William Paolini in the most popular astro forums. We are very happy about his extremely positive conclusion and would like to quote the following line: The latest Baader addition to the Morpheus eyepiece line up comes across to my eye like they saved the best for last. In general the comments on the Morpheus 17.5 and the improvements to the complete eyepiece series (new eyecups with integrated metal threaded ring, index clip, etc.) in the popular forums are...

  • Optical tube lengths of Clicklock mirror diagonal

    Recently we received the following questions on our 2" Clicklock Diagonal Mirror and wanted to answer including the below illustrations for other customers: According to image below is the optical path mentioned in technical data (112mm for #2956100 and 109mm for #2956100Z) measured along optical axis from point A to B or point A to C? what is the dimension from point B to C? Can 2” barrel (at point A) be removed from #2956100 and exchanged with another accessory (is it available?) to change the diagonal to #2956100Z (M68x1 thread)? Please note below our answer and adjusted graphic: The optical path of 112mm is measured A to C. The lightway from A to B would be ~71,5mm. Please note that the final endpoint of B is 3,5mm outside of the prism body (as illustrated in the below graphic), it looks just like point A in your drawing The Dimension from B...
