Dan, have just had a quick look at your gallery. What beautiful places, I think I would probably wear out my camera in similar places. And you have taken very good photos of them.

Hope you don't mind my viewing, thanks.

Thanks Dan, appreciate your knowledge.
Soon as I get my main computer rebuilt and running, I must give that Dust Mapping a run.

Using a very old computer at present, a stand-by, but has very little mem, and HD space, so used mainly for networking in emergencies.

Sorry Dan, this was me, I forgot ...

Hi Dan

Thanks for your time, I had read that, but thought I had missed something. It seemed too simple.

I just wonder, will this also show dead pixels?

Thanks again

Can you please tell me, how do you make a dust map using HeliconFocus.

I understand the taking of an out of focus image of a white object, but what next?

Please excuse me if this is something simple, but I have not had any experience of this.

Thank You.
