Considering the Sun is supposed to be heading towards a solar maximum not much is going on!

Today’s Sun–through the cloudy bits!

25 February 2012 JPEG25 February 2012 Annotated JPEG25 February 2012 Long & Lat

The clouds played havoc today – Bizibilder took around 190 pictures of the Sun but only 60 were cloud free!!  Just little “smears” of cloud but enough to stop the computer from stacking the images properly.  So all a bit rough and ready!

M44 “The Beehive” or “Praesepe”

Picture saved with settings embedded.

This is another Open cluster in the constellation Cancer.  It is named after the triangular shape of the brighter stars in the middle of the cluster – said to resemble an ancient style of beehive.  This was taken on 19 Feb 2012 and is around one hour exposure.

Messier 67 – 19 Feb 2012

Picture saved with settings embedded.

This is about an hours exposure on an Open Cluster of stars known as M67 in the constellation Cancer.  It is special in that many of the stars that it contains are very old and red in colour.  Most open clusters are filled with comparatively young, bluish stars.  The cluster is about the same apparent size in the sky as the full Moon.

A Couple of Galaxies

Picture saved with settings embedded.

Bizibilder has done these two before but not with this imaging set-up.  This image was made from 60 x 5 minute “subs” to give a total exposure time of 5 hours (and for the tekkies - an additional 30 darks and 28 flats to get rid of camera artefacts – a total of 118 separate images.  The targets are Messier 81 – the spiral and M82 also a spiral galaxy but seen edge-on to our line of sight.  He has spent hours(!) processing this one, using a set of tutorials posted on the web by a fellow imager.

Finally a clear sky, if a bit cold! So Bizibilder was able to spend some time on these.  Hope you like them!

A (sort of) break in the clouds:

Just enough of a break (leaving lots of high haze!) for these to be taken this afternoon.

A slightly warmer Bizibilder photographing the Sun!

The Sun today – at least it was around PLUS 5°C today which made taking the photo’s a little more comfortable!

It was FREEZING today!  But clear with moments of quite good seeing.  Todays efforts are presented here for your perusal.

A Moon Mosaic from 31 January

Bizibilder finally processed this one – it’s a 21 pane mosaic – not too bad he thinks!

Making a composite Astronomical image of M42

Bizibilder has finally completed his composite of the Orion Nebula.  The three images below show the parts used to make the final image:

They are stacks of 5 minute sub-exposures, 45 second subs and 15 second subs.  Bizibilder needed these as the nebula has such a huge range of brightness from the core (burnt out in the 5 min subs) to the outer extremities.  These three images (a total of three and a half hours of exposures) were combined in Photoshop to give a final composite:

First quarter Moon

Well, not quite first quarter, about 55% illuminated rather than 50%.  I’ve put a link to a big pic as this isn’t too bad for once!
