Clear Skies and nebulae

On Tuesday I took Astrosoc out to the University of Birmingham Observatory at Wast Hills for a BBQ (pictures from the social side later) and a night of observing. It was a fantastic night with probably the most clear skies I’ve ever seen at Wast Hills, for the visual observers they claim to have had the best view of the Milky Way ever at Wast Hills (to even see it is a almost a shock given we aren’t too far out of the city).
Since the title of the post includes nebulae lets start with them. We managed to get some decent images of some lovely nebulous regions. We started off the night, well it was still fairly light when we got this image, with the Ring Nebula (M57, 2x30s BRV):

We also observed the Lagoon nebula – M8 ( 2x10s BRV ) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region.

The Veil Nebula, also known as the Cygnus Loop or the Witch’s Broom Nebula, is a large, relatively faint supernova remnant in the constellation Cygnus (2x30s in BVR).
The Veil Nebula
We took a quick view of IC5070 – Pelican Nebula (30s BRV) – I’m pretty sure we can do much better than this quick snapshot but it does show some nice dense gas clouds:

M97 – Owl Nebula (30s BRV) showing the eyes and maybe a bit more – slightly deeper required:

M27 – Dumbbell Nebula (30s BRV):

IC 5146 – Cocoon Nebula (30s BRV):

A close second to the Veil nebula in my favourite image of the night, M20 – the Trifid Nebula is an H II region located in Sagittarius (2x30s BRV):

We weren’t so successful with the North American Nebula, NGC7000 – North American Nebula (30s BRV) taken at Wast Hills – clearly no nebulosity can be seen (thus we either didn’t observe deep enough or in the wrong patch of the nebula as it is fairly large):

Star Clusters:
Wild Duck cluster (M11; 30s BVR)

NGC6760 – a globular cluster in the constellation Aquila (30s BRV):

Galaxies:
Moving a bit further away… M63 – the Sunflower Galaxy (30s BVR):

M108 (30s BRV):

Stephan’s quintet – 4 of which are part of a compact galaxy group (30s R):

M31 – the centre of the Andromeda Galaxy (30s BRV)

M51 – The Whirlpool Galaxy (2x30s BRV):

NGC 6822 – Barnard’s Galaxy is in this field though not very clear, it is probably the faint nebulous region (30s BRV):

Last Week In pictures

My week started off with my Monday evening astronomy class at the botanical gardens… we actually got to go observing! They have a few of the trees there lit up for Christmas, looks quite nice and its not too light polluting:

On Tuesday I took a quick trip out to the University Observatory to fix an issue with our imaging camera… all sorted. It was a lovely day, unlike today (I was intending to do some observing out there tonight):

I also went to the IoP public talk here at the University of Birmingham on Tuesday night (the talk was excellent and it was on the “Star of Bethlehem”) and there was a lovely sunset beforehand:

Ok so maybe not a full week but I’ve not gotten around to sorting out the rest of the pics from the week as I’ve got a cold….

Home sweet, home…

… is not in Alabama! I’m from Birmingham in England (the original Birmingham!) but it seems our city council are destined to think we are actually in Birmingham, Alabama…. [Chiefs admit Brum skyline mix-up ]. Bloody idiots. Anyone who has lived in Birmingham for a few years would easily be able to tell you, though it looks like a city environment, that is not the Birmingham city centre skyline… oh and I think I have one of those leaflets somewhere!

IYA2009 Trailer…

The International Year of Astronomy 2009 has a trailer… so be prepared…

Save physics, forget the cheerleader.

As I’m sure you are all probably aware by now, if you read this blog you are, Physics is facing a massive cut in funding (about £80million, so 4 premiership football players!). The reasons are multiple and you can read many of this elsewhere, such as at [www.saveastronomy.org.uk]. I recommend you taking a read there, it has all the background stuff you need to know. Anyway, yesterday the undergraduates at Birmingham did a sterling job of trying to promote the petition to the UK prime minister.

Oh and if you believe that this should be stopped show your support by petitioning the UK prime minister at: [http://petitions.pm.gov.uk/Physics-Funding/]

The War On Democracy Documentary

The War On Democracy by John Pilger – I watched this the other week and I meant to post about it then – this is an eye opening (and independent) documentary that I would recommend anyone watched. He shows how the USA is undermining so much progress that Latin American countries such as Venezuela are making… if you want to watch it you can find it [here] (google streaming video)

Black Google Would Save Energy

It is believed that an all white computer screen, such as the Google page, uses 74 watts to display, whereas a black screen consumes only 59 watts and so a black version of google, such as blackle.com would infact save energy! Sounds ok, apart from the eye strain doesn’t it? Well I’m not entirely sure I believe it though as surely this doesn’t apply to LCDs… not sure though, but the Wall Street Journal backs this up here.
Maybe its worth it.. but I think I’d rather not deal with the awkwardness of reading and save energy elsewhere…
