Polemaster field of view question

Recommended Posts

Anyone know if the polemaster will work in this location? It did on the top of the losmandy plate (maybe 100mm further from axis) but I wonder if my tube will obscure the view?

I read a field of view of 11x8 degrees. My polemaster is 450mm from the end of the tube and 50mm above the tube. If my math is right then a 4° angle at 450mm is 31mm so the polemaster shouldn't be obstructed?

Proof will be in the test next clear night but interested to hear what people think.

My maths is good (or at least the predicted outcome is the same!). I managed to find a small break in the cloud and confirm there is no obstruction in this configuration.
