Hi Peter
Looked at and saved you mosaic of carina. It is now a desktop background.
Superb picture. Is that what you were doing whilst we were chatting last night.
Having slept on the issue we discussed I would like to confirm my understanding. see attachment.
My logic was based on scenario 1 whilst yours was based on scenario 3.
Is scenario 3 beyond the scope of my meagre equipment. My logic tells me that scenario 3 is really deep and the domain of high end equipment and scenario 2 is the limit of budget equipment.
BTW what do you do in the aviation industry? I spent 5 years as an avionics tech in the late 70's and early 80's. Had to get out of the business as every time the was an aircraft accident i would rush off and check my logbook to see if I had worked on that aircraft at all and contributed in any way to the accident. Couldnt live with myself if I had contributed in any way so left for less nerve wracking pastures.
Regards
Steve
