PIRATE data contributes to Gaia follow up

posted by Ed on 1 November 2016

This week's Gaia image of the week is a graph of a microlensing event, which many observatories around the world have been helping to follow up. Included among these is our newly commissioned PIRATE telescope, seen credited at the bottom.

Featured Object - The Needle Galaxy

posted by Ed on 9 April 2015

Galaxies are often very faint objects. It can be difficult to see the fine detail without very long exposures. Not the case with edge-on galaxies. With the stars of the galaxy in-line, the galaxies appear much brighter (though with less area).

New Request Constructor

posted by Ed on 23 January 2015

The most important part of interacting with the telescope in Tenerife - the request constructor - has just been upgraded. Over one year in development, this latest iteration should be quicker and easier to use, no matter what you are using the telescope to do.

Featured Object - Comet Lovejoy

posted by Ed on 13 January 2015

Comet C/2014 Q2 (Lovejoy), now around its peak brightness of magnitude 5, can actually be seen with the naked eye. But using Cluster Camera gives a far better view.

Featured Object - The Flame Nebula

posted by Ed on 27 October 2014

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.

Object of the Month - Veil Nebula

posted by Ed on 12 August 2014

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.

Master Dark and Bias Frames

posted by Ed on 5 August 2014

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.

A Guide to Filters

posted by Ed on 8 July 2014

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.

Object of the Month - The Milky Way

posted by Ed on 24 June 2014

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).

Object of the Month - Trifid Nebula

posted by Ed on 20 May 2014

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.
