Hi Greg,
Removing the nose piece allows the air inside the filter wheel to heat the CCD chamber.
For anyone who wants to help?
Getting back to this Newt:

I am trying to see if it would actually work with my QHY9 camera & a
2 focuser?
The QHY9 has only a 22 mm diagonal quite a small frame.
That would save me a lot of money as I have all the 2 accessories: OAG, coma corrector etc
I used this program on the web:

Please see the attached picture see that there are many problems..
I dont have all the right dimensions to plug into the calculator so I had to guess some e.g
tube inside diameter
tube thickness.
I need the right dimensions to use the 2 focuser?
I have asked TS.
Starlight 2" Feather Touch with dual speed ... no price change

That focuser made in the USA is one of the best and most stable focusers for Newtonian telescopes in 2" with a very low profile. We recommend that masterpiece of engineering for the use with heavier cameras and accessories. The overall height of the focuser including the basis is only 45 mm which results in perfect illumination of standard camera sensors.
Maybe I can get away with the 2" focuser?
cheers
Allan
