update

Hi,

A bit of an update on the filter wheel.....

Yesterday I finally got the courage up to do the 48mm chop
to the OTA of my 12"Newt to allow the filter wheel/ camera assortment
to reach focus.

Quite an easy job, saw the 12" F5 mirror up close for the first time

I spotted the terrible light leak that Alchemy talks about in his very
informative 'chop your Dob' article....got a photo of it here.
Some pics attached, I can reach focus!
It was funny, until I actually did a test last night on Rigel, I was
a bit panicky....It's not like I can add 48mm back on the tube

Ready to test on the sky now....

Steve
