The program should memorize last parameters. Very useful app. Would be better if last entered parameters (objective diameter.,...etc) are saved on pressing 'submit values' and then exit the program, so that these parameters don't need to be re-entered each time the program is activated. .... understand that this load/save feature is available in the pay version, but seemed that this is not compatible with my device (Samsung Galaxy SII). Wonder why???
You are on right track...some ideas... Useful on my Android...takes place of similar program I have for Windows. Night vision great plus. Ideas for more features. -add ability to find FOV for various CCD chips and different focal length scopes -Save previous inputs to save extra typing....just change one option like eyepiece focal length
Inaccurate exit pupil size I inputted the info for my spotting scope and it tells me my exit pupil is a mere 2.7mm! Its actually about 20-25mm!
Good call on the night mode option
