I believe i am correct, but then again, i could be reading things incorrectly.
https://skywatcheraustralia.com.au/p...rit-refractor/
The specs says:
Diameter of the corrected field 40mm
And the description tells me:
A 2-element field flattener is included to iron out the natural off-axis astigmatism and field curvature of the objective lens, leaving a fully corrected 42mm field of view
Unless i am reading something incorrect here?
