Dear List, Many thanks to those who emailed me regarding my questions.
Due to these emails, my "lost" memory was somewhat refreshed. Someone actually sent me some 4 year old correspondence that we had regarding this same subject. You don't know what you don't know..... In my case, i didnt know that i forgot that i didn't know that i didn't have the correct equipment for the quality pics i expected. "adaquate" objectives are just that--adaquate for casual viewing but not for the high quality pics i'm looking for. Back to the drawing board for me. Thanks All, John #1896 ----- Original Message ----- From: "John Lutzon" <[email protected]> To: <[email protected]> Sent: Thursday, May 19, 2016 5:36 PM Subject: Thin Section-Xpol Greetings List, I hope all is well with everyone. After a un-planned hiatus, i'm beginning to reassemble some of my equipment and again hope to take pics of TS's. In the past (before my coma) I remember taking some decent pic's but never recorded scope, lighting or camera settings. I will eventually re-figure those settings. Years ago, regarding one of my MPOD TS pics, a comment was made (by a well known and respected member) that my colors appeared "off". He inquired what objectives I was using. I have several microscpes with "adaquate" objectives. Thus, my questions (finally): Is the distance to the object pertinent to the bottom/top polarizer on the Z axis? Assuming Both polarizers are at 0 on the Y axis (extinction)---IS there a certain angle/degree on the X axis (either polarizer) that shows the "true" colors of a particular meteorite? Or, does one need to isolate a particular mineral color and the remnant colors are what they are?? As always, All best John Lutzon #1896 ______________________________________________ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list [email protected] https://pairlist3.pair.net/mailman/listinfo/meteorite-list
