There are plenty of great telescopes around. I've owned (and own) at least a dozen telescopes (combined) from A-P, TEC, and Takahashi. Optically, they are all outstanding. And it's nearly impossible to choose between them when comparing side-by-side, as I've done countless times over ...
High-energy astrophysics studies celestial phenomena involving extreme energy levels, such as black holes, neutron stars, and supernovae. It focuses onX-rays, gamma rays, and cosmic rays, providing insights into the universe's most violent and energetic processes. Advanced telescopes and detectors ...
the 90mm optical tube, front cell and Lens Shade feature the textured off white finish common to the 13cm and larger Astro-Physics telescopes; this will "blend in" better if the "Stowaway" is employed as either a wide field Finder telescope or as a photo-guide telescope on top of a larg...
Astro-Physics and Company Seven have allocated all planned production of the much prized 105mmf6, 130mmf6, and 155mmf7 Apochromatic Refracting telescopes for the first half of the year 2001. This is the first instance where we have accepted orders since all planned production for 1999 and 20...
The CCDT67 design allows full corner-to-corner illumination up to an 8300 or APS-C size chip with most catadioptric telescopes. This design does not add coma to the wavefront, and thus, can be used with all flat-field and coma-free telescopes such as Maksutov-Cassegrains, Schmidt-Cassegrai...
After AP stopped the 155EDF production in 2003, they started a new production in 2004 of the 160EDF. AP continued to offer these different designed 160's to people still on the unfinished 155EDF list. The 160EDF production stopped at ~100 telescopes a couple of years later. No other 6"...
we've got tests in an exceedingly satellite circle; a modest bunch of sunlight-based material science missions, area telescopes, and a bit armed force of Earth-watching satellites. Within the Earth circle, the International space platform keeps on setting out round the planet with a perpetually ...
Astro-Physics has been producing state-of-the-art telescopes, mountings and accessories since 1975.
Nevertheless, the Traveler is still one of my favorite telescopes and is occasionally used in Bifrost Observatory, but more often on portable mounts and tripods. Recent uses include total lunar eclipses in 2007 and 2008 as well as a stunning occultation of Venus in 2009. ...
