Thanks all.
The filter is an unmounted 2 inch one, that fits in at the rear of the lens. Of course once in place nothing can be seen in viewfilder so before fitting it I line the camera up on a bright star, then adjust the guidescope's 8x50 finderscope on same star, and use that to point the camera, short 5 second test images at ISO 1600 reveal the framing. I always have the laptop plugged in so as soon as an images is taken it downloads it to the laptop where I can examine it for framing and focus.
