A very small, wide-field, guided imaging rig Part 1. The equipment

The mini wide-field imaging scope is based on the latest edition to the Touptek family of guide scopes; the Touptek GS PAPO Guide scope. It is a 4 element self-flattening Planar Apochromatic ED refractor. It is truly tiny: F = 100mm, D = 25mm, f/4. it has a 1“ imaging circle and gives good stars to the corners of a sensor such as the Sony IMX 533.

The scope plus its guide-scope

I have written an article about Part 1 of this project. Full details including all of the images can be found HERE.
