very nice image Duncan

Looking excellent Duncan and the stars seem pretty good to the edge.  I would say in this LT the background looks blacker that a black thing painted black - but probably not much you can do about that without some gradient removal tool ? I didn't get to see the orginal but the colours look ok on this one.

Looks really good Duncan, nice detail and colours.

I can just make out the gradients or whatever, looks like a couple of arcs across the bottom of the image.  It looks like you could be picking up a reflection from somewhere.  Were the Taj Mahal lights on ?  I thought your tube and dewshield were flocked though.
Is it possible that dew could be collecting on the inside of the dewshield at the open end ?

Thanks everyone, yes I made the background very black to hide the gradients/artefacts. It could easily be reflections, I probably should flock inside the t-mount as well.

I don't think it was the Taj Mahal lights Mick, I need to examine the flats, I think there may have been light leakage when I took them. The funny thing is it looks like the effect you get when the back of a film camera isn't sealed properly or you don't put the lid on the film processing tank properly before you put the lights on. Weird.
