The Stellalyra Ultra Flat eyepieces provide a generous FOV and excellent field curvature correction, so stars are pin-sharp across the entire visible field, even in fast optical systems. All Stellalyra Ultra Flat eyepieces have fully multicoated optics and blackened lens edges for high light transmission and contrast. The color correction […]
The Starfield 0.8x adjustable reducer and flattener makes finding the correct back focus simple and easy. Setting the adjustment achieving back focus is simple, and, if more adjustment is needed for fine-tuning all that is needed is a small twist. If you are using accessories such as filter wheels and […]

The CCD Guide 2023 is now available. Every year since 1997, the Astronomischer Arbeitskreis Salzkammergut astronomy club in Austria has published the CCD-Guide, which assists astrophotographers in planning their imaging projects. Besides a huge number of reference images, the CCD-Guide contains software to find images, to view images and to […]
The AstroShader app has been released under beta. It was created as a specific iOS app for end-to-end imaging using the iPhone exclusively for image capturing, stacking and editing. The goals include making it easier to take longer captures and stack images on mobile without using a laptop/desktop and offer […]
The Star Hop Trainer App was created for iOS and Android to help those new to using a telescope learn how to find objects to view. While seasoned observers may take it for granted, star hopping is the skill of learning to find telescope targets by following patterns in the […]
Vātes-Astrographs are an intial offering from NAURIS, a new telescope company based in Germany. According to NAURIS, the idea behind the telescopes was to create a concept that incorporated designs meant to compliment the rapid development and performance that cameras equipped with CMOS sensors have undergone in recent years. The […]
The ASCOM Initiative Alpaca Workbench for Raspberry Pi has been released for the amateur astronomy industry. If you are interested in just learning about Alpaca, or developing apps/drivers that use Alpaca, and if you have a Raspberry Pi 32- or 64-bit with Bulldog OS (Buster 32 is OK too), this […]
