Pixinsight Newbie Tutorial Video's
 
 

These video tutorials are to ease the new users into the wonders of Pixinsight

I will not be talking too technical during the videos concentrating on the how and leaving the why for another time

but I aim to show that good results can be achieved fairly easily.

I can assure you once hooked on pixinsight you will wonder how you ever managed without it!

I hope they are of help and let me know if you have further suggestions

If you find the video's on my site of help please consider a small donation to help me pay the costs of running this site , the main cost being the host costs as the bandwidth usage is quite high. Even a pound will help !

    It is Also the workflow that I use on many of my images

    If you wish to experiment with the M106 images in the video's you can download them here

    M106 RGB ( 70 meg )
    M106 Lum ( 14 meg)
