For my own records I record here that I have solved why ALL SKY PLATE SOLVER does not show a JPG image when converted to a FITS file as I was doing it. After some fiddling I found that the JPG image when saved as a FITS file has to be converted to a monochrome image first. Unless this is done the JPG image saved as a FITS file will have NAXIS = 3 ( in the FITS HEADER) which signifies a colour image even though the original image was captured with a monochrome sensor.. Converting the JPG image to a monochrome FITS image results in NAXIS =2 (in the FITS HEADER) and then ALL SKY PLATE SOLVER will display the image after it has been plate solved. This now removes the need for NOVA.ASTROMETRY.NET (and thus an internet connection) and Astro ImageJ and thus will speed up matters. Thinking ahead I think I can now automate much of the measuring procedure involved. I recount my experiences here as it may assist others in their method of attack. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Thu Nov 19 2020 - 03:53:03 UTC
