Flat ground for dobsonian?

[Dom1961]

Can you only use dobsonians on flat ground? This is due to my garden being on a slope

If it is a manual dob and the scope is stable, it'll work just fine.

Have fun

No, they can sit at any reasonable angle.

Just as long as they are not going to slide at all, and the same is relevant for you. :grin:

Only the GoTo type needs a flat surface, the GoTo is very accurate when on a flat surface.....

 Manual Dobsonians are easily operated, with that being said placing the base on a flat board helps a lot. My backyard is like an ocean and I've not been able to find a adequate location . So improvisation is the only way I can sit and view for hours, I use my adjustable leg shower chair I got for $15 at a thrift store and works for 6 yrs. so far and I shim the board for AP.

Most folk I know with manual dobs face this challenge. I have seen adjustable feet, the odd paving slab and a few bricks. Just make sure you are safe, along with the glass bits that may drop out of the focusser...

Push-to dobs don't need a level surface, although the flatter it is the more comfortable it'll be to use.

I've never had mine on flat ground. If the base has three feet you can move it about to get it sturdier. I've always just shoved a bit of wood under one side if the ground is partially uneven. I've had it on a bit of a slope before, that wasn't so great but it still worked. Just a bit more effort to push it I found.
