Hi Mike,

I was wondering how you combined the 5 photos together. If you have the time, please let me know.

Respectfully yours,

Hi John.

I used a program called "Registar", which registers and aligns the images together, and then combines them to reduce the signal to noise ratio and brings out more detail.

Other programs can also do the same thing, such as Registax and Iris.

Here's a link to the thread on the UT forum (now BAUT) with other pics and more details.

I hope that helps, please feel free to contact me for any other questions.
