Hi all,

I have not tried this yet, but about to download the new pixinsight
version 1.9.
Note it comes with a "XMARS" data set you can download as part of it,
reference data on the complete sky to help better correct gradients, It is
a bit better than graxpert. I include a link below for a blog that compares
multiple methods, I am not ready to discuss, I need to try it out, but
giving all a heads up.

FYI I have a great contact in New Zealand who has given me access to all
his database sub images, in return I am giving him helpful (I hope) hints
at better processing.

All this reminds me that our photographers haven't met in a while. The
second Monday in January is the 13th, which would be our regular night.

Happy New Year, and let me know if there's any appetite for a Zoom at 8:00
pm Monday 1/13.

Hi Mario
Thanks for the information. s mentioned the other night, I have beenplaying around wit the JWST data (as described in Sky and Telescope). I did not follow the authors instructions for combining in Photoshop; besides I only have PS5.1 which does not have the functions he described. So I wanted to merge the different channel frequencies in Pix. Previously I had always used the Multichannel Synthesis script in Pix but the newer vesion of Pix dropped that script. I was reviewing my notes from our meetings and could not identify the function to perform the process.  I still have the older version of Pix on my older pc so I've been experimenting with SHO-AIP for now. Any suggestions with the newer Pix would be helpful
Thanks
Barry
