Great Work!…just did some star trails myself at Joshua Tree N.P. and really enjoyed it

I still have a very small gap which is visible at 100% magnification which I think is down to the cycling time of the shutter/mirror. I am planning to play with longer exposures typically 1-5 minutes using dark frames instead of NR to reduce the number of the gaps.

Kevin, thanks so much for the detailed post and great photographs. I too have a 7D and have the same gap problems you mentioned, even after turning off noise reduction, etc.

It looks like you were able to remove all the gaps. Which method did you use to do this? I’ve looked at the links you mention but there are various methods described, from Photoshop blending algorithms to rotating the photo over itself to fill the gaps.

Which method worked for you?

Thanks so much once more.
