PIER-14 Possible NGC 7000 3-pane?

hi ray

out driving all day, just got home

I will ask Phil if we can put an area in the pier 1 or 14 area where you can put a list that you update or even an archived jobs section (just spitballing)

remember we only input them for you and let you all know when they are finished. So we don’t keep a list

Steve

Steve,

That would be great. We understand we will need to maintain it :-).

At the worst we could create a 'Jobs completed' thread where we just add each job and its details as they are finished and downloadable.

Hi Florent,

It was just Richard and I at the time that did that mosaic. I'm very happy to go ahead with this job, after all it will be different being a HaRGB image. Doing those particular panels first will make a very nice image, so maybe wait a short while then decide whether or not to do the other two. The view will be a bit different to what we had anyway due to camera orientation, besides being broadband with Ha added. I'd recommend a second submission to capture just O3 data so that we can also create a HOO version. Maybe Richard has some other suggestions. 

Regarding your idea to store a list of targets already done, unfortunately it's only the roboscopes team that can create and maintain these. Anyway it's always going to require a bit of give and take by all of us when it comes to imaging something that's already been done. It wouldn't be fair to anyone new not to be able to capture something just because it's already been done. Besides all of us can always do with as much data as possible and could take the opportunity to combine the new with what you have and create a better version. 


Thanks for your very thoughtful suggestion and I apologise for inadvertently putting you in an awkward situation which I never intended. We're all in this together and can, within reason, image what we want. 

Best regards,

Ray

There was no problem at all  Ray

We dont see the boundary of the 3 pane at all i think , only when you know where the default are , pixel peepers doom 


I ve just resubmit a NGC7000 mosaic as i didnt know that you have shoot one earlier this year. mine is in RGB-Ha 

Do you want me to delete this new mosaic do not spend hours of clear skies on the same target again ? 


i think that we should think about a way to store in a single pinned post on the forum ,  the differents target that are completed (with the jobs number) so that we wont reschedule same target again and again. What do you think of ? 
ex 
Target1 (Common name, Messier , NGC,..)  :  2 pane mosaic , job xxx yyy yyy , Date mm-yyyy , link of post if any

I finally got around to processing the narrowband 3-pane mosaic of the NGC 7000 region from SH2-119 to the Pelican.

I struggled to balance all three panes and I still have some pinched stars at the boundaries, but I am going to stop fiddling for a while and process some other data.



Had another version that for some reason I can't post, but I think I overdid the processing anyway and prefer this one.

[Edit] - Ha, managed to upload it!




I think I will try a two-panel of NGC7000 and the Pelican. SH2-119 is a much weaker nebula and changes the balance of the image.

I have processed and cropped the centre panel.


Interesting that with the true dark areas between NA and Pelican you can clearly see that there is extensive nebulosity everywhere around the main emission.

I think this is a better crop

Hi,

Just a thought. To Steve and Phil.

I know that this will involve additional work, but any possibility of downloading what has so far been collected for job 998, 28.6% completed. That job has now been replaced by Richard's submission 1014. I like making crops from some of the images we can get from this set up. When the new job 1014 is available then we could have the option to combine what we have collected from job 998 and 1014 and get a slightly better crop of the Pelican nebula. Pretty please.

Cheers,

Ray

Just resubmitted the Rho Ophiuchus as well.

We both got caught out by the angle of the camera, mind you it has finally forced me to make use of the mosaic option in Telescopius. Of course that's assuming I've entered the scope and camera data correctly! Thanks for resubmitting that job Richard, that is going to be such a fabulous mosaic.

Richard,

That's excellent! Wow, have you given any thought to resubmitting it with revised coordinates, subject to set up staying unchanged for now.

Great colours, and personally I don't worry too much about the halos,. Certainly it would be nice if there was an easy way to improve them. Having looked at many Hubble images, they don't appear to be too concerned, so I take my lead from them.

Cheers,

Ray

Just submitted - job 1016. Hope I have the coordinates right this time!

I have processed the left pane as a stand-alone image of SH2-119 (Clamshell Nebula). The brighter star haloes could do with some work, but I think it is pretty good.

I have just realised with the angle changed, we had the OAG removed and added some spacers a couple of months back if you remember and then took new flats

Obviously the angle acted a little

Cool, at least your getting to grips with it

Did you see the other thread I have opened re to reduce or not to reduce on P14 ?

Cheers

Steve

Steve,

I have commented on that thread. I think it is OK.

Please note that new job 1014 replaces 998 (only 14% complete). It is a correction for the camera angle being different to the assumption I made (idiot!!).

I will hold off on any further mosaics until we get the reducer removed.

I will check through outstanding jobs to see if there is anything that would be nice to finish before the change.

I have submitted a new job (1014) to replace job 998 (North America mosaic right panel). This has corrected coordinates to line up with the centre panel we have already received. It is a bit of a kludge, but will give us a nice 2-panel of the North America and Pelican nebulae. if we continue with 998, I think we would have to crop part of the NA out. I hope this works out.

Hi Richard,

Well done, I should have checked the equipment page rather than making assumptions. It says 80 degrees, but after applying a 14 degree rotation to one of the images it then pretty much aligned with one taken last year. I assume the camera on that pier was pretty much vertical. Hence I had no problems myself.

Need a bit of time to consider what to do now, but I can definitely pull a few of my recent submissions if that would give time to resubmit that pano. Could have been worse if you'd put the Sadr region in first.

Correction, the angle is of course the other way:

OK, I now understand what has happened.
I stacked the Ha for both panels, aligned them to each other and used GradientMergeMosaic to make a crude combined image (no fiddling about to deal with artefacts at the boundaries). Gives this:


So the same kind of slippage between panels we saw with the Heart and Soul mosaic.

I used ImageSolver on each panel to check actual coordinates, and they are correct. HOWEVER, I noticed that the camera orientation is 104.8 degrees, not the 90 degrees we had been assuming for portrait orientation. This has a big impact. The correct layout for the mosaic should be this:


With distinctly different coordinates for each frame. We are only 14% into the right panel, so it may be worth reframing.

We need to revisit any mosaic in the queue to see what effect the coordinate error has and replace jobs if necessary.

I am glad I did not submit the 4-panel Sadr region mosaic. That would have been a disaster.
