    I had a go at capturing star trails this evening. I took 32 x 15sec images over ten minutes with my Fujifilm S7000. Back home I ran these through a stacking program from http://www.startrails.de and got the following composite pic.



    It was feckin' freezing but good fun

    I've been meaning to do a set of loads of 30 second exposures.

    Do theses stacking programmes eliminate noise?
    Is it best to use Mirror lock up too?

    I'm loving the pictures on this thread. On the one hand it reminds me how crap my photography is, but then on the other it just inspires me to try and do (and learn) much more

    Some rubbish ones I took with my little 75-300 lens a while back:

    The Plough

    and

    To infinity

    1 x 20 sec exposure each.
    Lots of light due to it being a city center back garden.

    Some really amazing pictures in here. I want to have a little look into the sky but I don't want to spend too much, would something like this be a good buy? Would I see much with it?

    Love the star trail and plough pics

    Stacking is the best way but as always it’s time consuming. To get rid of noise you have to take “darks” These are done with the lens cap on. The dark frames must be created with the same exposure time, temperature and ISO speed of the target object. The software then has a reference of the noise that the camera is producing. It then subtracts the noise from the main picture.

    There are also other reference pics you can take (Bias & flat frames) but it starts to get a bit complicated - as does multiple exposures to get the whole object correctly exposed. The nebula pic is layered from 2 exposures, one for the outer region and the other for the core. With more exposures it could be improved on.


    Rather than the Sky-Watcher Visiomar 60mm, I would go for a Skywatcher Startravel 80. I have one and they are great – a bit more compact and portable too. You can also stick the camera onto it to get a big cheap lens!

    Have a look here

    I would go for one without a tripod (called an OTA) here

    http://www.firstlightoptics.com/prod...p?prod=st80ota

    Then buy a cheap tripod off Ebay

    It's worth mentioning that even with a pair of bino's, you can see a lot more than with the naked eye

    I remember stoating back to my stand from the toilets whilst absolutely wrecked at JAE last year and noticing how bright the stars were, pretty awesome sight. But it was 6am and i was freezing, so i took more interest in viewing my pillow

    We had another clear night in Winchester on Saturday I had another go at a star trails image. This time I took 184 pics over an hour. Here is the result.

    The trails are much longer but i should have checked the ISO. I took these at ISO200 when 400 would have been better. Never mind, it's good fun, just waiting for the next clear night

    Deep sky stacker and nebulosity. It takes ages to get a decent image though. Spent a few hours last night and got nothing I am taking pics at the moment but don't expect to get much as it's a bit hazy - Astro types call it poor transparency

    Grazor, them pics are great What's the lights on the bottom right of the pic though

    The lines along the bottom are car headlight trails from the A34 through the hedge at the end of the field. The squiggly line above the horizon bottom right is a plane just taken off from nearby Southampton Airport
