Targetted some HEO and GEO objects while testing a new lens, a SamYang 2.0/135 mm lens that I received yesterday. This lens has been on my wish-list for a while and will replace the aged 2.8/180 mm Zeiss I previously used for GEO and HEO. It is very sharp and outperforms the Zeiss. At full aperture (with an APS-C sensor EOS 80D) it is still quite sharp near the edges of the FOV (unlike the Zeiss). It also has a larger aperture than the Zeiss, showing fainter objects. The FOV, 9 x 7 deg, is wider than that of the Zeiss (7 x 5 deg). It is much less in weight. So far, after this first trial I am very happy with it. 77-114A had not been reported since 7 months ago. - Marco ----- Dr Marco Langbroek - SatTrackCam Leiden, the Netherlands. e-mail: sattrackcam_at_langbroek.org Cospar 4353 (Leiden): 52.15412 N, 4.49081 E (WGS84), +0 m ASL Cospar 4355 (Cronesteyn): 52.13878 N, 4.49937 E (WGS84), -2 m ASL Station (b)log: http://sattrackcam.blogspot.com Twitter: _at_Marco_Langbroek ----- _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Thu Jan 16 2020 - 09:48:40 UTC
