Venus 2nd Contact in Thousand Oaks filter

文章 HK.Raymond.Tse » 週二 08 6月, 2004 17:57

Dear all,

These are 2 cropped images of 2nd contact of Venus Transit at HK time 1.29 pm and 1.34 pm. Taken by Canon 10D with 135mm lens + 1.4x barlow with Thousand Oaks Sun filter at ISO 100, F8 , 1/90 sec.

Images under Thousand Oaks are orange in colour, rather than pale purple white under Baader film. I personally think that orange clour provides a more contrasty look.

Focusing is done by eye and therefore not very sharp.

Raymond Tse
