Re: Venus Transit 2012 photos by Mr Chia
Hi,All
Thanks Gary for the upload and Cataclysm for the reply.Sorry for the late post after the event due to my computer crashing.Now I am only using a year-2002 Viao computer and it takes tons of hours to go through my photo.Now for the transit--Initially I intend to use as much as 8 scopes to record the event--this is due to the fact that after 2004 observation and photographing,I notice that whatever I do--in spite of using an fluorite apo--there is a slight halo around the dark image of venus on the sun in those photos.These 8 scopes are--3 in Ha of different bandwidth--0.6A;<0.5A;0.9A
--3 in white light view---132 mm refractor in thousand oak filter type 2 ---camera direct zoom 39 times with thousand oak type 2 filter ----80mm refractor with self assembled filter system at 540nm
---2 in Cak light--one at 2.2A bandwidth
--one at higher bandwidth to accomodate the CaH line too.
However due to bad weather,my dream was smash and due to the clouds,I only set up 3 scopes,namely--Ha at <0.5A;80mm refractor with self assembled filter system ;camera direct zoom 39 times with thousand oak type 2 filter--all these can 'cut through' the thin cloud/haze and can offer some kind of image.As expected,the Ha view did confirm the presence of the halo around venus dark image disc on the sun.The least showing of this come from the 540nm view--quite a surprise to me.However my dream to photograph/see the ring of fire around the dark venus disc when venus exit from the sun were smash.No more chance in my lifetime.Sad.
