NGC7000 mosaic, a nights imaging wasted.

[MikeD]

Getting to be a bit of a theme for this mosaic.

This all started as a single image with 15 minute subs to which I added a new pane form another year( 7 minute subs) as the two overlapped.

I then decided to go for a big mosaic but wanted to shoot all the panes the same sub length.

So I dumped the 15 minute subs and re shot that and last years data all in 10 minute subs.

All was now going well until tonight when I stitched the raw stacks of the 5 x panes ( now all 10 minute subs) I have so far and processed the result as one image to see what I had so far.

It was then that I noticed the data from last night (bottom right pane) had out of focus stars on one side.

I have just been out to see what was up and found this.

After breaking down the imaging train to do some Solar imaging I didn't notice when resetting to image DSO's the washer I cut one edge off of on my filter wheel to give me the space I need to attach my CCD had rotated and caused the CCd to be mounted on the tilt.

That will teach me to just set a run going and go to bed without having a good look at the first sub.

There is also some blending issues with mosaic but this was just a quick put together to see what I had, I will take more care with the next attempt.

Hi Mike - That initial image of nuts/bolts on the floor looked a bit scary when I first opened this post, but the image looks great to my eyes... I'd be REALLY pleased with it!

If a thing can go wrong it will...

But it looks great to me. You can easily run a star rounder action on any stars that displease you. I have one saved as a keyboard shortcut action. The TEC gives tiny distortion in the corners and with no flattener (750 dollars!) I just cheat for the few stars involved.

That's bad luck. Mike but at least you found it. Looks like the start i

of a great mosaic.

The end result is looking good though Mike. We need these little reminders sometimes to keep us from getting complacent.

Wasted a fair few hours of data myself when I have forgotten to check out the rig and fallen asleep at the helm

A great start to another one of your projects Mike. I'm looking forward to its completion

Thanks guys.

Thanks olly for the tip, though I would still know that the nebulosity was also soft focus so it's going to have to be a redo.

I had a proper go at processing this and applied a fix for the stars (thanks for the push Olly;))

Thanks guys.

Another pane added, though conditions were not great for the last shot.
