I will not be using this particular lens again for serious satellite work as limiting magnitude is not faint enough and useless for geostationary work. (2) the next lens to be tested is a French TV camera telephoto lens operating with a focal length of 15mm to 150mm at f/2.8. It will be relatively easy to motorize the focus and focal length adjustment. Image quality looks very good but first impressions are it does not go as faint as my 145mm lens. Examination of the optical elements shows signs of fungal growth and numerous small scratches which will only serve to scatter light and reduce performance - this is probably why the lens was scraped and I got it for nothing. Beggars cant be choosers:-)) Cheers Greg ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
