Less than a 2x barlow

Hi all

My DMK won't come to focus at newt focus in my 10" newt - it needs more in travel, or the mirror needs to be moved up the tube.. similar to if I tried newt prime focus with my 350D I guess.

So I've only got the 2x barlow to use, which gives me too much image scale on some objects, when I want a widefield of the moon, sun or even if I want to try and get a DSO with this camera. Especially with the length of the filterwheel and adapters, it probably gives me more than 2x.

I know there's such a thing as the 1.6x antares barlow isn't there?

Are there any other barlows less than 2x? As close to 1x as possible would be ideal.

I don't want to move the mirror up the tube at this stage, and I've got a moonlite CR2 focuser and don't want to make it any low profile, as it might affect my long focal length imaging.

Thanks
