Thanks for the advice Chetan. I shall try again and try to locate the polaris.I think you have got an excellent set of images for a first try.What I would suggest is to do two things:
1) Make sure the Polaris is a part of the frame so that you get the entire circular trails in your image. The starting part of this thread has some notes about finding the Polaris.
2) Most important part is to get something in the foreground. The star trails should be a part of the image but you need to have a subject which grabs your attention. See if you can compose the images accordingly.
Thanks Henry. Ill sure try out some more today. One question - theres hardly any difference in the length of the trail between the 2 pics though the 1st one is stacked out of 10 shots while the 2nd one has been stacked out of 100. Also why is there the gaps between the trail. Is it that the interval between the 2 shots needs to be reduced.The pic. is very good for the first try. As Chetan said you need better composition, you have nailed the exposure. Try some more.
Yeah Zack I know. The problem is that I could not find anything else to focus on in my garden while at the same time trying to cut out the street lights. Ill try some more today, try to locate the polaris and put it up for critique. Thanks.
