Design of SHG

[Bastelhannes]

Because I cancelled my cooperation with the astronomy dealer (some Sol'Ex kits were laying around therefore), the weather is depressing and I always wanted to have a high resolution motorized SHG:

I played around in Fusion360...

I am printing it over the next days.

It is like a mixture of Christian's Sol'Ex and the UVEX4 from the "nice People".

Hi,

How much will you charge for the design ? I assume you are using the 28BYJ-48 stepper motor, right ?

Will you sell the optical kit or is it the kit from Shelyak ?

Danke und Grüße Rainer

Hi Rainer,

it is the optical kit from Shelyak. We intended to sell it for interested customers. But because I left the shop suddenly my colleague pressed me the parcel with some kits into my hands. It is just a design for myself to prove if it is possible to motorize the "easy" setup.

I used 6 mm aluminum pipes, three 28BYJ-48 steppers, one GT2-belt and the optical parts from Shelyak. All other parts are going to be printed.

When it is working I am thinking about what to do with it. I mean, if I publish it as open source, just put it in a drawer or offer it. No clue so far. At the moment I am really done with direct customer contact (I started to understand, why astro guys do their hobby alone in the dark - never expose them to direct sunlight).
