Subject:      mag and alignment

Thanks for the magnitude info. I also found some ways to do with a very
involved way with colors and the stars and using formulas.

Meanwhile I found the procedures to begin making color images. Everything
works right except color does not out as I can't align the pictures quite
right even when I use a guide star as a target.

Any hints at being more exact and making it work?

Is there a way to determine magnitudes of stars with NIH?

Dr. Flescher,

A Google search on

nih image magnitude of star

produces a number of hits, the first of which is

http://helios.nmhu.edu/bryan/research/work/m67/nihphot.doc

This is instructions for measuring star magnitudes with NIH Image and
the macro

http://helios.nmhu.edu/bryan/research/work/m67/photometry.txt

A similar search on

ImageJ magnitude of star

gives one hit that is not about this subject (it appears to contain
imagej as a typo).

Bob
