Quick image taken tonight after 01.30 BST. Using the charts on heavensabove I was able to track down asteroid 4 Vesta with ease around mag +7.0. It was located within the head of Cetus.  |

Nice thread started, Martin!  Vesta is bright enough in your image, why don't try to make a shorter exposure to avoid the star trails? Vesta is going to reach +6.4m in October, so wait for my images too For more information about currently bright asteroids visit my page http://www.poltava-astro.narod.ru/asteroids_eng.html |

Thanks Roman. Yes, Vesta is an easy binocular object now and is very well placed for observation. I was using the lens zoomed in quite a bit there so had to use a longer exposure to get the depth. I don't mind the trails at all, if I dropped the exposure to minimize trailing then I wouldn't pick up Vesta very well at all. Trailing comes in handy for faint objects. While imaging a Nova last year, which was at the limit for my camera, I found I could find it due to the fact that it was trailed like the other stars. If the camera was driven I couldn't rule out that it could have been noise etc. Comes in handy sometimes |
