Default 1st star trail, & a ?

Ok, Is it normal to have red & blue specks on the photo? They don't appear on here but it did when I opened it. Please ignore the dirty house

How did you do this shot in the daytime ? Wow I didn`t know that was possible...That`s magnificently cool !I don`t see any red or blue specs, but that could possibly be noise or dead pixels most likely.

This was done at night.
The long exposure and post processing has brought out the 'light' sky and made it look like daytime.

Lisa any red/blue specks that may be visible in the original full frame is due to long exposure noise and/or hot pixels.

Thanks, I thought my camera was messing up (shows what a noob I am)

Yes, it was done at night the moon was off behind the camera.

To reduce the glare from the moon, (I don't mind a bit of it...in fact I prefer a bit of sky-glow with such pictures), what you could try doing is shortening the exposure time. At my site, 3 or 4 minutes is usually the limit, (at ISO 800 or 1600 I mea), so I don't go much above that. If I'm doing trails I might even just set the exposure to 30s or 1 minute, put the camera into Burst mode, then lock the remote shutter down. I go away and let the camera take dozens and dozens of images over the course of an hour or so perhaps. Then I stack the images together using something like Startrails.de.

The bonus is you can instead stack the images into an animation package or something and make a timelapse!

I'm the noob, I've only had my XS for about a month. This forum has been a great help.
