Improved OpenAstroGuider scope

thingiverse

This is an improved version of the already great OpenAstroGuider and mounts to the new aluminium base. Whats new: - Added thread between front and mid part to simplify focusing and make it more precise - Lens hood holds the lens now (instead of friction only which was dependant on 3d printer tolerances and other factors) - Made new 20x20 extrusion holders which can be mounted without the need to disassembly the main camera mount - More precise guide camera sensor mounting improves polar alignment and guiding - Camera sensor mounted without screws now - Supporting many different camera modules as long as they have have same screw holes - Reduced overall required screws amount - multiple further small improvements What you'll need: - Achromatic lens with 50mm diameter and 182,8 focal lenght - Camera sensor performing well in low light (e.g. AR0130 or IMX290). Monochrome sensor recommended. - 2 x M4x8 screws - 2 x M4 t-nuts - 4 x M3x12 screws - 2 x M3 hex nuts Printed at with 0.15 layer height and 4 perimeters. Dark filaments improve signal to noise ratio by preventing light from the side (e.g. laptop) to hit the sensor. Update 21.10.2020: - Added more tolerance to the printed threads to fix issues on some printers
