Description
In the world of amateur astronomy, a new innovation has emerged, revolving around improving the Dwarf 2, a budget-friendly mini telescope produced by Dwarf Labs. This telescope, notable for its ability to capture deep sky objects, features a dual-lens system comprising a wide-field and a telephoto lens. However, it initially lacked the capability for long exposures using the wide-field lens, a limitation that paved the way for a technical breakthrough.
The key advancement involved integrating a GoPro with Night Lapse functionality into the telescope setup. This adaptation allowed for capturing extended 30-second exposure time lapses, which could be seamlessly converted into stunning videos.
The design process was repetitive and focused on precision. Measurements of the Dwarf 2 were taken to develop various mount designs, ensuring a snug and functional fit for the GoPro. The outcome was a series of mounts, each serving a distinct purpose and enhancing the telescope's capabilities.
The first significant design was the 'Claw' unit, a multifunctional mount capable of supporting a green laser for polar alignment and securely holding the GoPro above the lens tube. Following this was the 'Sidecar' tube, an attachment that facilitated all-night time-lapse photography while the telescope tracked objects in the night sky, enabling the stacking of images of nebulae and galaxies.
The documentation provided with the final designs highlighted the intricate assembly process and the specific hardware utilized. Emphasis was placed on the 3D printing aspect, with each component's orientation on the build plate meticulously planned to optimize strength and effectiveness. The Big Gear Shaft, for instance, was positioned horizontally for enhanced robustness, whereas the Small Gear Shaft was oriented vertically, a choice influenced by its additional hole, which provided extra strength.
Material selection was another critical aspect, with PLA being the primary choice for filament. Experimentation with TPU soft filament yielded positive results, particularly for the cradle part of the mount. The use of tree support structures in the printing process facilitated easier removal and cleaner finishes of the parts.
A crucial component, the Drive Wheel, required a small rubber band or O-ring to ensure proper traction with the telescope's rotating tube. These bands were resourcefully repurposed from Wyze Camera cable packages. The rest of the hardware was conveniently sourced from online platforms like Amazon.
This technical innovation in amateur astronomy highlights the impact of thoughtful design and precision engineering in enhancing the capabilities of existing equipment. The project stands as a remarkable example of how integrating modern technology, like GoPros, with traditional telescopes can unlock new potentials in astronomical observation and imagery.
