Hi
I also only have 18-55 lens, will this be ok just for getting used to it?
Thanks
Yes, you can use a kit lens to shoot the stars. The hardest challenge you face is that at night you won't be able to get it focused. So here is what you do.
1. Aperture wide open
2. Lens at 18mm
3. ISO anywhere from 1600-4000
4. Need to be as far away from city lights as possible. Maybe hit that puddle that surrounds your country and swim a good ways out heading west. East will not work so well as you will run into other countries.
5. No moon, unless you're shooting the moon. The moon is far brighter than you realize and will wash things out.
6. During the day, or just before dark, go outside and focus on the farthest thing you can find. Once the focus is set, switch the lens to manual and put a piece of blue painters tape (here in America it's called blue painters tape, it's blue and it's used for painting in the house) on the lens barrel and across the focus ring. This will prevent it from losing infinity focus.
7. Mount camera on tripod
8. Switch camera to live view
9. Trigger camera either by remote or use the self-timer. You want nothing to bump or jiggle the camera to include the neck strap swinging around.
10. If you have a UV filter over your lens to protect it, as I do, remove it. The lens filter can cause unwanted reflections. However, I would actually do this part before I set my focus for the evening. Unscrewing it could move your focus ring.
Finally, post up some pictures once you shoot some. You may not have ideal conditions right now, but shoot stars on any given night just so you learn what all is involved. Experience in the worst conditions will teach you so much that will really help when you have ideal conditions.
