The object we'll be looking at this time is the Flame Nebula. This little know nebula is very easy to observe, in terms of its brightness and its size.

I am excited to present the very latest version of our online FITS editing tools, now live on the site for you to use. While other sites either provide a static jpeg or (sometimes) give you a FITS file, which you need specialist software to open, we are unique in offering a simple-to-use interface for editing your data, right in your web browser. Our newest, third generation FITS viewer is going to push the boundaries of what you thought was possible in a web page, and the first stage of the release is now live.

The Veil Nebula is not an object that has traditionally been popular with the users of the BRT. I can only assume that this is because it's not very well known. With the right settings this object can produce quite nice images.

In order to get a good image back from a CCD on the back of a telescope, there are a number of processes you have to put the image through to account for discrepancies and errors. These include applying bias and dark frames as well as flat fielding. We handle these for you automatically, but for those that like to do things by hand we are now producing master dark and bias frames for more advanced users to use.

There are a wide range of filters available on our cameras. Different cameras have different filters. These filters have strange names, which may be confusing if you've never seen them before. I dedicate this post to explaining what these filters are and when to use them.

Our telescope is pretty uniquely capable of capturing images of the milky way in all its splendour thanks to the wide field cameras you are able to request images from. The only difficulty is working out what to point at, as the milky way takes up quite a lot of the sky. (Or all of it you could argue).

There is a lot of gas and dust in space. Most of it we can't see because both the dust and the background of space are very dark. Generally speaking, there are three different reasons we might get to see this dust. The Trifid Nebula (Messier 20) is a great showcase for this as it demonstrates all three in a single object. This also makes it an interesting object to try and image.

Over the last week or so I have been doing some investigating into the algorithms that control the positioning of the dome throughout the night. It has been a long journey full of pitfalls and surprises but it might be leading to better dome positioning from now on.

There are a few galaxies around the skies of the Northern Hemisphere which Charles Messier somehow missed when he was compiling his famous Messier Catalogue. One of these is the galaxy NGC 2903. Discovered by William Herschel 15 years later, this bright spiral galaxy has an unusual textured core.

Galaxies can be very beautiful objects to image. They are all unique, can often have very intricate spirals, and don't take much work to get a good picture of. The tricky part is knowing which galaxies to take images of, as there certainly are a lot! Over the past 18 months I have been taking images of some promising galaxies and here I present the results of that endeavour.

On the 4th of July 1054, a bright new star appeared in the sky. Astronomers is China, Japan and across the Arab world took notice and of course it was heralded as an omen of great importance. This new star was a supernova explosion and while the initial glow faded long ago, the aftermath of this explosion is easily seen with a telescope: the crab nebula.
