Pier extensions and Imagining

[Ford Prefect]

Hi

I'm looking to purchase a pier extension  for my HeQ5 imaging rig, I just need to get a bit more height to see over the observatory walls, the mount is fixed to a 10" pier and runs a borg 77 and WO72 guide scope so its not that heavy.  My question is does anyone have any experience in imagining with a pier extension as I'm worried it will effect the guiding/images.

cheers

If the extension is attached firmly to the pier, I do not see how it could affect imaging (but I may be imagining things )

One of my robotic clients used one of these atop the short permanent pier that lives in the shed. It worked OK. When he switched to a taller mount he sold it to another robotic client and we cut it in half to get the right height for his rig. It still works. So I'd say it will be what you're looking for.  It isn't going to be as stiff as a system without it but you are not stressing the mount with your present scopes.
