Thanks for the report.

Photoshop question

Posted By Miguel Olivares
Press Ctrl-Alt-Shift right after clicking the icon to open Photoshop to reset all preferences, Option-Command-Shift on a Mac. I hope that helps.

Processing or Hardware Issue?

Posted By Miguel Olivares
Aaron,

Try Iris:
http://www.astrosurf.com/buil/us/iris/iris.htm

Open the command console and type:
>fftd x y
>ffill 0
>save x
>ffti x y

Set the threshold window to 255 (top slider) and 0 (bottom).


See: Fixed pattern noise removal, about halfway down the page.

This only works with black and white images. For color images, you will need to separate the RGB channels, and work with them individually.

Any full moon lunar observing tips?

Posted By Miguel Olivares
Virtual Moon Atlas, a must have program if you observe the Moon.

It lists areas of interest near the terminator.

Simple photometry for Comet Holmes

Posted By Miguel Olivares
Got a lucky break, and I had a chance to see the comet tonight. It was very easy to find from my light polluted location, and hazy skies. Very impressive view through 10x50 binoculars, extremely bright, almost planetary in appearance, pale yellow color.

Weather may not improve until Sunday, but I'm keeping my fingers crossed.

Thanks for the tip on estimating its magnitude.

Great job John.

I got about 20GB of data to process from last night. Will post something later today, too.

Can't wait to see what this comet will do next!
