I reprocessed images, and I was able to go litle deeper, I think.
The data is yet "thin" and more exposures are needed, maybe an other ten hours.

image about whole imaging systemThe Business end of the lens
Accurate focusing is needed doe the very fast lens. At f2.8 the sharp focus zone is about 20/1000 mm! Focusing by hand is a pure Lottery. I have TCF-s focuser and its temperature compensated, so thereis no need to refocus every time when temperature drops.
The focusing system has been build from the scrap metal and some parts found from
Its very easy to move the focuser back and forth between main scope
and the lens.
There is a right size can lid bolted down to a L-shape body.
Focuser is then atattched to the lid.
In a focuser, there is a brass tube. This tube goes back and forth when focuser moves.
Its then rotate the focuser ring of the camera lens. There is peace of fine sandpaper glued
to the tube to prevent slipery, tube has allso a spring load for the same purpose.
I have used TCF-s focuser but it can be any focuser, even manual one!
It will make focusing easier and less random.
The whole project took about three hours of time and cost 50c (I had to buy
The whole assembly is then attached to the dowetail rail at top of the LX200 scope.
This is a second version.
The firs version was made by blywood, but I made it again with metal doe flexsure problems.

CROSS VISION INSTRUCTIONS: In cross eye freeviewing the image for the left eye is on the right and the image for the right eye is on the left. You stare at a point about 1/2 way to the screen so that your eye's gaze is crossing at the half way point. Thus the left eye sees the correct image which is on the right. As you cross your eyes the image will go double. When your eyes are crossed the correct amount the middle images will overlap and be in 3d. The two outer images will remain and will be in 2d.
