Have you ever wondered how the telescope optics are made in amateur telescopes? Even is the answer is no, you might want reconsider that answer and take a peek at this video where Explore Scientific’s Scott Roberts provides an inside look at the telescope optic’s manufacturing process. It’s a short […]
Ostahowski Optics has announced they are currently in the process of planning their 24-inch primary telescope mirror production for next year. They are taking pre-orders for the mirrors and will be ordering the fused quartz substrate soon in order to have blanks ready to process by the first of next […]
The SPIE (the international society for optics and photonics) has released the 2019 version of Robert Schalck’s book, The Proper Care of Optics, Cleaning, Handling, Storage and Shipping. Telescope optics are the heart and soul of any observing setup, yet they probably get the least amount of attention by most […]
In understanding my approach towards creating SkyTools 4 Imaging, its worth considering how major professional observatories, such as ESO, use mathematical models of their telescope and instruments to plan their observations. It is useful to know the image scale, what exposure times to use, whether a star will bloom or […]
Catseye Infinity XLKP Autocollimator Collimation Tool: Newtonian astrograph telescope users can now confidently take autocollimator focuser-axis alignment to the next level of precision without the need of a focuser drawtube extension. By design, Newtonian astrographs incorporate a “back-focus” position of the primary mirror’s native focal plane to facilitate image focus […]
Astrozap Telescope Dust Covers: Astronomers can get pretty finicky about cleanliness, especially when it comes to their telescope optics. The reality is that dust is everywhere and it is next to impossible to keep it entirely off a telescope’s optics. However, you don’t have to allow dust to settle on […]
Although Robert Schalck’s book, The Proper Care of Optics, Cleaning, Handling, Storage and Shipping, has been around for several years, we were recently reminded of it on a website forum post. Telescope optics are the heart and soul of any observing setup, yet they probably get the least amount of […]
