How to do better moon images (I thing...)

Dear friends.

I will want to explain that I've done some tests to obtain Moon images with high definition. I had tried to use the multistack way in Registax, but this excellent software creates ugly lines dividing each zone.

I am testing Helicon Focus making micrographics images of minerals. This software uses the best focus area of a series of photographs that have been slightly changed the focus to create a composite image. In this way, the software provides a picture in which all the elements that appear in the photograph are focused. On the Web Helicon Focus you can see many examples.

I thought that when we stack a Moon AVI, the definition of the details is good only in the area marked as a reference to stack. The definition decreases depending on the distance to the staking reference point multiplied by a factor of seeing, and if a crater is farther away from the reference point , more worse will be their focus.

What I've tried the same process has been often AVI (25 ...) taking different craters as reference stacking around the surface of the image. Then I tried these 25 images with Helicon Focus and the result was amazing! A perfect definition throughout the image. I encourage you to try. I believe that even in high-resolution images of Jupiter can work well, but the AVI has to be good, better than mine.

A fully operational trial for 30 days can be downloaded from its website.

PD. As ever, sorry for my bad english...

Well, Mike, I am changing my dome adding engines, because with the new
telescope that I go to install I will not open it manually.

I have asked an AVI of the moon, but seeing it was quite bad and the camera has produced some strange frames that illuminated the area below. Anyway, the result is very good for seeing who has the AVI ...

Better, I show a image with 5 differents stacking areas. You can see that these areas are better that the rest of image.
