thanks for those experiments and testes, i wish i could come that sat, (sat is not a holiday for me)
and thanks willis for the report
Borg 7887 got strange result...
as I was a research student, it's not surprised that experiment and real life test (in vitro vs in situ) aways show different results (especially in my medical field), it's always multifactorial.
seems optic research may got similar situation
, sometimes frustrating, or we should be excited as there maybe something new which need investigation
and as I still a newb in astro, and still learning observation, and waiting for clear sky, i am not hurry for photography yet
add oil for all of us
