Sidereal Trading are happy to announce the release of the saxon FCD100 Air-Spaced ED Triplet Refractor Series. These telescopes feature Japanese Hoya FCD100 optics. Relying on technological innovation, Hoya have successfully launched the high-performance optical glass at the apex of the FCD family. Hoya FCD100 is considered the best glass ever produced by Hoya.
Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, these telescopes generate brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer deposition on all optical surfaces.
The saxon FCD100 Triplet Series is available with 80mm aperture 480mm focal length F6 optics, 102mm aperture 714mm focal length F7 optics and 127mm aperture 952mm focal length F7.5 optics.
In addition, these amazing Telescopes include a dual speed (10:1) 2.5″ focuser featuring a very rigid design with strong support. Up to 4.5kgs of camera gear can be loaded onto these focusers.
Having a true diffraction-limited optical design and sized to encourage spontaneous stargazing sessions, these high-quality telescopes are a perfect grab-and-go instrument for exploring the skies.
Sampling rates can make your stars good or blocky, especially if you zoom in. It all depends on a few factors like your focal length, the size of the pixels in your sensor, how good the atmospheric conditions are, and even how good your guiding is. This article shows how to get a combination of telescope and camera that will give you nice smooth stars under a range of conditions.
This is an instalment of a tutorial series on how to slave a dome. In this part we look at connecting the dome control software to the dome and mount through the ASCOM Hub. Depending on the connections you can perform the slaving calculations in the dome control software or the ASCOM Hub.
In this second part of the dome slaving series, we discuss connecting your observatory control program directly to the dome and the mount using ASCOM drivers. This is the simplest we to set it up, and allows you to use the observatory control program to do the slaving calculations.
