Extendable extension

[ibraidwo]

Has anyone come across an extendable extension before or come up with a design for one

The top and bottom parts could be separate and could 'telescope' up and down with tightened bolts to hold it in place (like an oversized tripod leg), or even the central tube part could be interchangable bolting to top and bottom plates (which could also be interchangable for different mounts/tripods...

Crazy idea or potentially a good one?

I know I need an extension to reach zenith but I don't know what an optimum height would be... so an extendable or adaptable one could solve my problem!

Maybe I should just go back to sleep

Be expensive if its not going to flex, be better to go for a range of extensions something like this.....they range from next to nothing to 3"

I think the OP is talking about height adjustment on the mount. TBH, even when maintaining alignment is not an issue, moving the centre of gravity up without widening the base is a recipe for disaster. I would go for an adjustable-height chair

Opphs, reading threads when also looking through the bottle of a whisky glass is always going to be a bit iffy........

Iffy or squiffy

Thanks for the responses. I have seen a number of pictures with extensions mounted on top of an EQ5 tripod to enable increased height for a long refractor. Is this not recommended due to stability and centre of gravity issues?

Have also just realised that if I did get a fixed height extension, I could always raise or lower the tripod to change the mount height

I used 3 electric jacks for my 'tripod' to level it. You could easily use one to raise and lower the mid section of a pier, using 12V :-)
