I used to get wound around the axle, for example, about side error. Frank told me that a little side error was a good thing because when it comes to determining index error using a faint star, it is far easier to determine the point at which they line up side by side, than it is to determine the exact point of superimposition. True. So very true. On backlash, Frank told me that even the finest sextants have a little backlash and that it is always best to adopt the practice of rotating the drum in the same direction when fine-tuning your sight. I have followed this advice and have never gone wrong. Same procedure used by myself. I too will note and record what backlash is present in both my MS-733 and my rebuilt Astra and report back with the results. P.S. I know this is not supposed to be a "political site", however, I must offer a salute and my heartfelt thanks and appreciation to our brave soldiers, sailors and airmen, past and present, on this day, November 11: Remembrance Day (Veteran's Day for my American cousins). God Save the Queen and God Bless America. Robert I, for one, as a retired U.S. Marine, appreciate hearing of your heartfelt thanks. And I would like to thank those who went before me and those who served after I did from any nation for his/her service to that nation. It's not about politics. It's about the remembrance of sacrifice. And your thank you was, to me, refreshing. To my nephew David, who is serving in Bravo Co., 287th Para. Inf. Regiment, 82nd Airborne Division, god speed young man.
