Sunlight on the edge of crater Halley.

This photo taken way back in 2009, with a 6 inch refractor, a wonderful telescope for imaging the Moon. 

Having viewed the Lunar features with several telescopes I have to say that six inch refractor was the favourite. 

Why I ever sold that refractor is a mystery!

Here is a close up of sunlight on the edge of crater Halley, from the above photo.

Even though the telescope magnification was low on the original photo, I was able to further increase magnification via some simple software.  

A bit of tweaking with copy and paste can have many uses when it comes to chasing down the craters of the Moon.
