line in processed image

I took a picture of Moretus to practice up for the October 9 rocket crash.

I need the practice because I am new to webcam and lunar imaging.

I got what you see below.

My question: What is that line that comes at an angle up from the limb? It seems some kind of processing artifact. I used Registax 5.

Anybody have any advice for it?

What scope and Camera are you using ? Any Barlow lens ??

Hi Alex,

I agree it's an artifact, unless maybe you've discovered the lunar version of the Great Wall of China. It might help with the diagnosis to know at what stage of processing it appears. Does it show up in any of the raw images, or the stacked/aligned image, or when you apply wavelets?

Alex,

Looks like you used the MAP feature in Registax. Sometimes Reg has trouble putting everything back together and you see a line like that.
