So, another cloudless night, how lucky we are. Disappointed with the results of two nights ago, I revisited the Soul Nebula, and this time get somewhat better quality in places that were disappointing. Here are the new results.
I may try and join the two sessions together and see whether I can pull any more detail from the two.
So. Now what we are able to do, if merge the results from Monday evening with the results from Wednesday and build a composite mosaic, I fiddled with the colour palette to bring out the detail. We can continue to add exposures and the mosaic would eventually lose the noticeable borders.
Seems everyday is fraught with issues, which emphasises the real need to following a set workflow for set up of your rig if you are not lucky enough to have a permanent set up.
Mistakes this time round included, but probably not limited to:
Forgetting to attach counter weight to the counterweight bar
Mounting Filter-wheel in the camera train pointing downwards (M81 is pretty much at the zenith for my latitude, and hence the filter-wheel collided with the mount during exposures – which had to be discaraded).
It’s a case of constant learning. I did draft a workflow document, but the weather meant I did most of the set up in the dark. Time to update the document with the lessons learned and remember to actually follow it in the future.
5 120s L, R, G & B exposures, no darks, bias, or flats used (was annoyed and kicking myself for the problems, so didn’t bother.)
This is one of my first long exposures (1hour 20minutes total) of M33. The light from this spiral galaxy has been travelling for 2.73 million years before the photons hit my camera to produce this picture.
