Does anyone know if one of these would work with the LPI?  I am looking for a way to get precise focus, and S&T were hawking these in the October issue.

I use the Bahtinov Mask and have found it the best of all the masks.  You can not use it directly on the moon, but rather on a star near the moon.  It will work with the LPI.

For those who use the Bahtinov Mask with a camera, there is FREE software, that will show you how far off focus you are down to a tenth of a pixel.  I have found it is better than my eye.  The software can be found here:
