Subject: Astonishing images with
4"
Dear friends,
I got very nice
steady seeing this morning (at 360x !), AVI files yet
processed. Starting from Saturday morning (July 19),
there was a strong evidence of Argenteus Mons and Novissima Thyle with my
"little" 4" refractor (Perl-Vixen
fluorite 102mm F/D=8,8 with tele-extender, barlow 2x and VestaPro webcam on Super-Polaris mount). Remember that Airy disk
diameter is 2,8" ! A small topographic white patch
is obvious between Meridiani S. and Margaritifer S. on July 19 image (blue and
composite). However, processing rules are not well defined and there are some
problems with RGB channels calibration. Waiting for IR-cut
filter.
Best regards,
