The light that is illuminating the “dark” part of the Moon here has travelled quite a long way! From the Sun to the Earth, where it has reflected back to the Moon, where it has reflected back again to the Earth and Bizibilder has captured it in his camera! This is a stack of 5 second exposures to show what is called “Earthshine”. The “light” part of the Moon is therefore severely overexposed.

Bizibilder managed to collect a further hour (see image in post below) of data on M42 last night before the clouds rolled in. This image is therefore two nights data stacked into one single image (aren’t computers wonderful?). It makes quite a difference to the depth of colour and detail that you can see. The “core” is a bit washed out as it is very bright so the next task is to collect some short “subs” to correctly expose for the brightest parts of the nebula and then to overlay them onto this image – weather permitting, of course.

Bizibilder finally had a clear night (with temperature just above zero and no gales!) on Monday (23 Jan 2012). So he took these test images with his (now not so) new imaging scope – a 120mm refractor. The first (top left) is M42 in Orion – this time just over an hour of exposure time. Top right is the Rosette nebula – again about an hour. Bottom is the open star cluster called Messier 35 (You can also see the smaller cluster NGC2518 to its right hand side). This one is 50mins of exposures. Bizibilder is quite pleased that the new scope is coming up to expectations – all he needs now is clear skies so he can get much more time on these objects!

Bizibilder finally finished his new telescope pier today and has installed it outside. He used it to mount a telescope for todays images of the Sun and was pleased to find it was as solid as a rock! Well worth all the effort of making it. It is positioned to allow Bizibilder to see the Sun from a position that avoids some trees and other obstructions when using the observatory.

A first for Bizibilder – Venus. As this planet is between Earth and the Sun it shows phases (just like our Moon). At the moment it is moving eastwards away from the Sun and will be getting much nearer to Earth as it moves towards us. You can easily see Venus in the Southwest after sunset – it is by far the brightest object in that part of the sky.
Jupiter is still visible high in the South after sunset. This sequence was taken on the 14th and shows the rotation of Jupiter over about three hours. There is also a picture of three of Jupiter’s moons – this is a composite of two pictures, one of the planet and one with a longer exposure to reveal the moons.

A few pictures of progress on Bizibilder’s portable pier – he has finally done some more work! To be fair last week was spent putting several coats of varnish on the timber ring that is now fitted below the pier top (and watching the paint dry between coats!). The waste bin makes a functional, if odd looking, cover over the mount. It sits tightly over the timber disc and will hopefully protect the mount against the weather and ferocious beasties!

This is a conventional series of Solar images from Bizibilder with an extra one thrown in! He has just purchased a new green (Wratten #58) filter to try and improve the surface detail from his full disc pictures. (The “green” image is the top right one – all the colours in the above images are false and are provided via Photoshop processing). Bizibilder thinks he is on yet another steep learning curve!
Better late than never! Bizibilder has been a bit busy over the last couple of days so these are posted a bit late! The first is taken with his DSLR camera (it is a mosaic of two panes – top and bottom). The second is an 11 pane webcam mosaic of the Mare Imbrium area of the Moon.
