As far as the reflection goes, are there any bright shiny metal parts you can blacken with a felt pen - like edges of adapter?

Hopefully it would be that simple.

Another solution is a mask over your camera. Apogee made a mask for the U16M and it is a thin, matt black aluminium sheet that had 2 small holes in it and fitted in front of the shutter. It works well with this sort of problem.

It may possibly be reflections from bright metal bits in the CCD chamber and the mask will also help with that.

You can make one out of black cardboard from a newsagent.

Thanks for the ideas Greg. This light rays issue is not an isolated incident, it occurs in a few of my images. It is generally not too much of an issue (one of my DM awarded images had one in it even ) and mostly I can live with it fine but sometimes, like in this image, I would rather they weren't there. If I could eliminate it or even reduce the frequency it would be great.

Bert (Avandonk) over on the SCP group has shown me the exact stars responsible and all three are quite a way outside the chip area so your idea that it may be refections of the inside of the camera near the chip sounds feasible?

I don't quite understand what you are getting at re the Apogee mask, could you email me to discuss? cheers Mike m.sidonio@bigpond.com

So thanks, i enjoyed it and found it very well made.
Bottom line its here for enjoyment, not judgement.

Its good to see the scope is able to get such good resolution from only 6" of glass. I would have expected this from a more dedicated optical configuration.

Aaaah yes.. a number of lovely people (and they are) are way too hyper analyitical of images, to the point where they are only looking at an image for it's imperfections and contest winning potential, or lack there of . A nice image is sometimes just that...a nice image, a minor flaw that is really of no consequence to anyone, other than someone with OCD, can be glossed over without fear of having missed giving that all impotant advice This doesn't mean that people can't pass on tips here and there of course but let the pontificating, over the top, analytical hubris go I say it's ok to just enjoy an image without feeling the compulsion to offer advice all the time, my mother and sister do this all the time, well intentioned but it really me mad

Yes the AP152EDF continues to amaze me with the clarity of image it can produce and I have been using it now for nearly 3 years

I love visual observing,but I also love a well taken image.
Well done and thanks.

Unfortunately imaging has taken my fancy for the last couple of years and sadly I do all too little observing these days. I used to at least look through the big scopes at SPSP but this year I didn't even do that!..prefering instead to hang around with those, autoguiding, amplifyer glow infested, image downloading, noise making digital wine drinking binned FREAKS
