New product! Duncam Collimation Masks
      #5545981 - 11/29/12 06:30 PM

Custom cut Duncan collimation masks are now available for SCT users. I need the OD of your optical tube, the OD of the central obstruction to cut them. If you want to fit inside of a dew shield I can work that out but it may require a template to be trial fit and returned.



As always I have custom cut Bahtinov masks available. I will need measurements of the optical tube for this also and how you want to fit, inside or outside a dew shield.

In the process of testing them for RC use. I was out the other night and it looks like it might work but by watching the diffraction pattern differently. I didn't see good solid center bars but the outer bar showed double rings and I noticed on my scope the rings were uneven to one side. I know my RC is off a bit so it makes sense.

I have 2 people who will be testing for me in warmer weather. This time of year in MN clouds outnumber clear and clear means deep cold making it hard to work outside.
