Eagle Nebula revisited

A combined image of Eagle Nebula. A 3.3 hr total light frame exposure captured over 2 nights a week or so appart. I think the image would have been better if all images had been taken during the first imaging run but this is what I ended up with.

Funny how your getting a 6 spike diffraction effect.
You have 4 in the others, very strange.

Is this a cropped image, looks small, would have been nicer for the whole image.

Hi Theo, Just an experiment.
The shot was taken over 2 nights so with the alignment a lot of image from both shots was lost requiring a crop to save the good part of the image. The extra difraction spikes are from misaligned fishing line over the 2 nights. In fact I quite like the multiple spikes and may make a multiple overlay.

Hi Doug, looks great

When you image over more than one night do you use any particular technique to re-frame the subject or just by eye? Does your software handle the alignment or do you have to do it manually?

cheers,

Rob

Hi Rob,

I try to line up as close as I can remember the previous image to be and let the software take care of the alignment and stacking.
