Took a yomp over the fields on monday morning to get a clear eastern horizon just after 6 am, as I was setting up Venus was rising through the early morning glow a scintillating red spot light. All images taken Canon 450D on tripod with cable shutter release. All shot in raw and processed in P.S.6
Having taken images , quick dash back home to get off to London, hence delay in processing!
First image 18-250mm Sigma at 87mm ISO1600, F22, 1″
2nd image 180-500mm sigma at 500mm ISO1600, F22, 0.25″
3rd image same lens as image 2, at 180mm, ISO100, F22, 2″
Moon 180-500mm Sigma , at 500mm ISO100, F22, 0.1″
Although closer the previous day, as usual the clouds got in the way, but for once the forecast for Friday morning was correct and in the east just after 6am Venus could be seen blazing away and as the eyes adjusted it was possible to make out the fainter orange hue of Mars close by to the right and slightly above, sigma Leo was visible above this pairing of Venus and Mars. Between 06:00 and 06:30 the pair climbed higher in the dawn sky before being enveloped in the approaching dawn.
Venus is shining strongly in the evening sky, even brighter than Jupiter in the morning sky, finally cleared the roofs opposite so had a go at imaging it, tried a different approach this time, have previously attached the DSLR to eyepiece using T ring and adapter, this time tried it with the DMK42 mono CCD camera with a red filter, to remove any chromatic aberration. Used 120mm Evostar refractor on HEQ5pro, sidereal tracking mode, max frame of 15fps with DMK41 , #23A filter attached, 600 frame .avi files recorded with, no magnification, x2 Barlow and x5Barlow, also imaged Mars to left and above Venus with no magnification.
All images produced from stacking .avi in Autostakkert, wavelets in Registax6 and final processing/sizing in Photoshop.6
Venus with no magnification, slightly gibbous (about 60%),will become larger and more of a crescent as it moves to Greatest Elongation in January.
with x2 barlow
with x 5 Barlow
Mars and Venus with no magnification, taken under same conditions.
Mars is so far away now, even high magnification only shows a red disc, with no features, a UV filter would be needed to draw out any features in the atmosphere of Venus. (Did you hear that Santa?)
Have a Good Christmas and New Year!
17:05 Moon rise over azimuth of approx 60 deg.
Another moon at “Perigee”

Venus was very prominent in the \Southern sky before sunset and as the2Peri” moon rose was framed in the branches of the tree behind me.
150mm, 5″, F22, ISO 1600.
Took these shots between 17:00 and 18:00 as the moon was rising over Burton on Trent, amazing how much dew had formed on the camera and lens body in that time, luckily none on lens!
The bright moon does not bode well for Geminid spotting and by dawn cloud will be covering the sky, which is unfortunate as the radar echoes being picked up increased dramatically over the 13th Dec and the log file for the 14th was also heading the same way, will post the activity profile at end of week.
