How are the photos taken ?

  • I currently use a very sensitive black and white digital camera ( a special one for astrophotography ). Various photos are taken through clear, red, green and blue filters. the combination of these results in a single photo, in colour with reduced noise. Typically a run of photos lasts 2-6 hours and finally the post production work, also a number of hours.

Why build an observatory ?

  • In order to obtain good pictures, it is essential that the mount is accurately aligned and calibrated. On a portable mount, I needed nearly one hour to do this and this barely surficed. With an observatory, it is possible to very accurately set everything up. When conditions allow, I only need to hook up a laptop, switch everything on. Usually within 30 minutes i am set up and photographing.

Difficulties ?

  • The main problem is light pollution. Luckily I live in a very rural area and this is limited, however 50% of the time one is limited by the bright light from the moon.
