3d printed finderscope extender

[glowingturnip]

Just thought I'd share my design for a finderscope extender for any folks out there into 3D printing:

 

 

I built this because I was finding that particularly at certain angles (pointing straight up for example), there was not enough room between telescope and finderscope to be able to get my eye to it properly, and an inch or two taller helps a lot.

Also since I'm into astrophotography and have a guidescope mounted on top of my main scope which peers through between the focuser tube and the finderscope, that putting in a 15 degree tilt to the extender gives the guidescope a lot more viewing room.

Just the ticket

That's really neat. Thanks for sharing.

why oh why can I see myself getting a 3d printer one of these days?

Because they're so extremely useful?

Nifty, made me a solar finde and lodestar mount already. What thread did you tap it with? Made alsorts of adapter rings and bits already.... very useful.

solar finder - that's an idea...  mind you, probably have to make it with ABS, no-one wants a melty finder do they.

Can't remember the exact measurements, but i made the inside diameter of the holes a fraction of a millimetre smaller than the outside diameter, and the screws (M4) do a pretty good job of tapping themselves

Yes, black PLA initially and got duke bubbling... it was mounted up the back of the refractor objective. Mounted on top a different design in a more

I must make one of those!

Meanwhile a 3D printed finder for pointing a DSLR for widefield shots with a bit more accuracy, also an excuse to turn Fluffy* into an internet cat:

blatant cat shot, I love it !
