Lot's of terrific discussion on lens design issues. This humble forum has recently produced much more useful/relevant info than I ever had hoped.
I have made a side by side pipe mount to do some simple optics comparisons. I have access to a couple of different refractors however, I am not so experienced at optics testing.
I have Suiters book, but it is slow reading :S Any simple techniques on star testing? Ronchi screen testing ? Autocollimation testing ? (I have a pretty smooth 8" flat) I could even post some digital pictures if anyone is interested. Thanks for any ideas !
(BTW The BO1278 is on the right.)
