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

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!

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.
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.

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.

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:
A full size (actually about 80% full size) is here: Big M42 Composite
