Levelling Thing?

[TopHouse]

I've been asked by someone if I can get levellers made, I do have a good contact for that kind of thing but I'm not sure I understand what he wants, does anyone know what I'm talking about if I say:-

it's for people using fork mounts and it's like an eyepiece fitting with a levelling bubble in it.

ie you don't look through it, (I don't think) but it's 1.25 i assume, but has a bubble on the top.

Does anyone have a clue what I'm on about?

I'm sure I heard of this sort of thing, it sits in the EP tray of a tripod, and shows that it's level, but what would that matter on a fork mount???

Would that be like the AE Alignmate that's on Astroboot?

Two devices come to mind. Both based on circular spirit levels. One, as Cootuk says, is but into a 1.25" ep housing. The other is the simple level stuck onto a tripod. For example for levelling an EQ mount. The levels themselves are cheap enough (<£2) to buy from on line tool retailers or ebay.

The impression I got from description so far isn't a tripod leveller like the ambubble thing, from the brief description I got, and my interpetation, is something about when setting up a fork mount, at some point you need to set the OTA dead level for something?

I know it's vague but does anyone know?

My knowledge of fork mounts could be written on a postage stamp, the front bit, in any white bits available.

Sounds exactly like the AE alignmate... 1.25" barrel with a spirit level in the top and a compass in the bottom. I had one for my ETX90 many years ago.

That sounds like what was described, can you please tell me what you do with it, and are they readily available everywhere? I know it fits in focuser, but why?

Thanks for that Steve, if they're readily available and so cheap, i don't know why i've been asked if i can supply them. Strange.
