Mars Image 2019/03/10(UT)
Stanislas Maksymowicz,Manos Kardasis
Here is a report of mars performed on the 10th with the 127mm apo refractor.
Images were average to good enough on small times (say 7/10).
Syrtis Major was there with unequal albedo (probably covered by a thin hazze),
the limb of the planet was hazzy occulting Mare Thyrenum.
Hellas was bright whitish with the W11 nd W80A filters,
brightness fades with the W8 filter. Was probably misty but this needs more investigations.
As well for the Xanthe area where the extension of the brightness〓looked over the said Xanthe area.
Both poles area were hazzy whitish.
I reassessed the refractor for a complete settlement yesterday,the triplet lens cassette,
the alignment of the tube and the collimation. his helped the production on this report
(say a 5" size aperture on a 5" planet disk size still capble!).
[Stanislas Maksymowicz Ecquevilly,France]
In poor conditions. Mars is near 5 arc secs.
North Polar Hood is evident but seems like shrinking as Mars is approaching equinox (and Northern Spring) in a few days.
