Starizona’s SCT Corrector IV – 0.63X Reducer/Coma Corrector and Optical Back-Focus
In this article Matt Harmston shows that, in theory, establishing ideal backfocus is straightforward: Insert spacers and accessories between the two surfaces such that their collective thicknesses match the manufacturer specified back-focus distance. However, as he details, in practice the fine-tuning of back-focus distance is a precision exercise. A few […]
Video Overview of the ZWO Camera Angle Adjuster Electronic Rotator
The ZWO Camera Angle Adjuster Electronic Rotator is a high-precision device designed to offer astrophotographers seamless and accurate camera rotation for optimal framing of celestial objects. By enabling remote angle adjustments, it enhances the imaging workflow, eliminating the need for manual intervention that could disturb focus or tracking. This advanced […]
Narrowband Sulfur-Hydrogen-Oxygen On-The-Cheap
In this review Jim Thompson discusses explain the process of capturing data to produce a narrowband Sulfur-Hydrogen- Oxygen (SHO) image using a OSC camera. The final title I selected for this article, “SHO On-The-Cheap”, is perhaps not the most descriptive, but it is at least better than my original title: […]
