Hi Doug,



is there a good way to obtain a value for the sky background ( magnitude/

arc sec **2 ) for a astro-photo treated by MaximDL?



Thanks for your advice in advance

Hi Anton,



Try this link, it certainly works for Maxim:



home.earthlink.net/~stanleymm/CCD_topics.html



and then click on "Calculate sky background from reference star".



I built a spreadsheet to do this with input from Astroart. It should

be easy to do the same for Maxim (which provides, if I remember

correctly, pixel statistics for a circlular area on the image).

Thank you Robert for the link,



it seems to work. But it would be interesting for me to get information

about the algorithm.

Yes indeed and preferable if you can use scripting to do this !

OK, I will dig the formula out of my spreadsheet and post it. But I

will only get to it sometime this weekend.

Hi Robert/Anton/Stan,



Could one of you post the algorithm here, or email it to me direct?



If so, I'll have a go at implementing it in a MaximDL plugin which

I'll then make freely available for download.



Regards,



John
