Thanks Guys, yes I have to admit it was a brave move,

and I cant wait to see the results myself.
Did a couple of test flats through the scope this morning to look for dust bunnies, hmmmm, I said to myself I see two of the little buggers in between the new filter and the sensor.
I hate dust, so they had to go, pulled it apart this morning, much quicker than the first time, and now all is well.
I feel satisified with the job and only the results will tell if it was worth the effort.
You know there is no turning back once you have that sensor in your hand
It is at the end of the job, when it is all put back together, when you cross your fingers and toes, and anything else that you can cross, stick the battery in close your eyes, and turn on the switch.
If you see that red light and the screen light up you can stop holding your breath and breath again,

if not your stuffed.
