---------- (1) Classified high altitudes identified. Still have many (!) strays to report but in a few cases confusion exists due to several satellites close together. Also about 20 "unknowns" found for which nothing matches in HEAVENSAT - the majority will be defects - ie cosmic ray strikes, dead pixels etc but will have to examine the images closely to determine whether real or not. (2) Used the setup in 1 bin mode which means enormous image files - 16 or 32 Mbytes ( dont know why sometimes 32 Mbytes as it should be 16 Mbytes but looks "normal" and processes okay.) Since images are 3326 x 2504 pixels they have to be examined a bit at a time since cant display entire image in full resolution. (3) All in all something like 800 positions on about 150 satellites - took about 6 hours to mark "satellite-like objects" in the images and APEX took about 40 minutes to process 99% of them. (4) New 8-inch f/4 reflector - doesnt look like arriving today and since not many people work on saturdays Ill only get it monday. The mirror is spherical - thats why cheap - but have organised with a local amateur telescope maker (ATM) to parabolize it if image quality not good enough. I swopped him some "surplus junk" for a 12" f/4 parabolic reflector on a dobsonian mount but this will only be delivered in a few weeks time.... Not exactly sure what Im going to do with it as FOV will only be about 1 degree with the CCD camera and I will have to build some encoding system to get adequate position resolution for remote use.... Will keep me out of trouble for some time! Cheers Greg _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
