PIER-14 July and August targets

One minor caveat Ray, choose different sky quadrants for your objects as that is also half the issue, you choose mainly stuff in the same area. If you choose 5 objects all in the same area rising then the software has nothing else to do when they all reach the meridian etc etc

You need to use more of the sphere and take into account the way the moon rises depending upon phase so it can image at almost all times of the month no matter what time or what part of the sky the moon is sitting in.

Its not just a case of “whats rising” amigo. if you try to manage the algorithm it will just be less productive. If however you image the whole dome ( E W N S Z) it will be far more productive. The reason it finished all your data recently was because I had to take over and personally manage it before the pier was stripped for maintenance ??

Hi Steve,

I assume a 'welcome home' is in order. I'm sorry that I didn't make it clear that this is what I think we should be doing when there are effectively too many objects we can image. By mid autumn I agree we should do as you suggest at the time when many of those emmision nebulae are setting.

I believe that right now there is more than enough to keep the pier occupied all night. Many of the qualifying targets can be imaged from the onset of astronomical night to the start of astronomical twilight. I'm very tempted to start making submissions based upon what Richard wanted combined with what is on Mike's list, but I set this post up to allow some discussion.


Adding those that are just starting to rise too soon and I can see a situation where we are kept waiting for data for those already starting to set. It is only when we receive the data back that we can evaluate it and make a submission to make up for any compromised subs.

I hope that I've now explained it somewhat clearer. I believe that I'm someone who is probably more keen than even you to make the most of the pier.

Looking forward to receiving back the short test submission I made as requested and new flat files.

Cheers,

Ray

Hi guys,

Just to let you know that I have just submitted a further 6 jobs so that we can assess the results without having to wait for too long to get them back. Most of them just capture data in hydrogen alpha and for less than an hour. Perhaps you wouldn't mind holding off submitting anything until tomorrow (Friday) to give them a headstart.

One is to assess the framing of the Lobster and Cave nebula in a single capture. I have already posted coordinates for Mike to use if he would prefer a 2 panel mosaic instead, capturing a wider view. So when that data comes back Mike can make a full submission, 3 filters, after assessing what we have, either as a single frame or mosaic.

I have also submitted 4 jobs for the Sadr region mosaic. Again only in hydrogen alpha, so that Richard can make any adjustments before submitting the full data collection jobs.

A final one is for the Lagoon and Trifid nebula while they're in a good position, not something anyone has requested, so I've gone ahead capturing ha and O3 to simulate rgb. That job is a bit longer at just under 3 hours.

The first submission I made 1041 Veil nebula has been used as a quick test by the team to assess the setup. That was a short run of around 3 hours, not the amount I requested, since that would have taken a lot longer to complete. I may therefore need to resubmit it with the full number of subs I originally used.

Hope you are all doing okay.

Cheers,

Ray

Looks good Ray.

Been looking for some new targets and wonder about SH2 - 132 on the Cepheus/Lacerta border. There are some nice narrowband on astrobin.

Richard,

That's the Lion nebula I believe and a good choice. I did tackle that one last year using pier 3 I think, it would benefit I reckon being in a wider fov such as this pier gives. Definitely gets my vote Richard as a good candidate for this setup.

I will add it when we know the final camera orientation.

It looks fine with our FOV

Hi Richard,

Unfortunately those jobs we're waiting on to establish the camera angle are not getting any time right now, so I hope you don't mind me submitting sh2-132. I was a bit wary that with not much left in the queue in terms of integration time, the pier might be left with nothing for a short time.

I've submitted this one since the orientation will definitely not cause any issues regarding bits being cut off, and I've done so as part 1 of 2 for now. Just under 5 hours in total and when we get the data back if you are able to find the time, you can can assess what we have and submit part 2 to add what you think we need to finish it. If you don't have the time right then, then I don't mind doing it.

Fingers crossed we get back what we need and that Sadr region can be started. A challenge I'm looking forward to tackling of an awesome region.

Cheers guys,

Ray

Not sure I understand Ray. Surely any image taken after the changes would allow us to accurately determine the camera angle by platesolving? I had assumed that the first job that was complete (and I see there are a couple listed as 100% in the job queue) would give us what we need. MY plan was to grab the first frames available, get the camera angle and then bang in the new set of jobs, starting with the Sadr mosaic.

However, no problem whatsoever with you submitting SH2 132. We agreed it was a good target. It does not matter who puts it in the queue :-)

Hi Richard,

Oops. You're absolutely right that's all that's needed. I was just trying to establish what the mosaic would look like using those approximate coordinates and overlap assuming Steve got it as close to vertical as is reasonably possible, but that's not really necessary with the mosaic planner in Telescopius. I have sent in a ticket to try and get one other job I submitted, which is no longer useful, removed from the job queue, so any of those 4 jobs still in the queue after you've put those for Sadr in can also be deleted.

Hope you are making good progress with work.

Cheers,

Ray

Ray,

Could not see SH2-132 on the submissions list, so I have put it in (Job 1067)

Added SH2 171 (Teddy Bear Nebula - job 1068)

Good morning Richard,

The Lion should be showing as 1049. I based my exposures on an image Peter did using Pier 7 a few months ago. If Steve reads this then perhaps he'd arrange to have my submission removed. I was being cautious over the time being required, your submission would give us more data, and I'm all for that.

That Teddy Bear thingy threw me until I looked at the image. I've seen it referred to as Ced214, Ngc7822 and Sh 2-171 never as that. Looks more like a gorilla to my poor eyesight. Prior to the recent visit I had submitted it but for reasons that escape me right now, I didn't manage to complete it. I'll look into that later and let you know what happened.

Cheers,

Ray

Ray

1049 Removed


If after we have re inputted everything now the changes have taken place one of you could check our submissions to make sure everything is correct I would be grateful, we are only human after all

Steve

Hi
there was a job complete on lagoon Nebula , but the coord were wrong (+24d DEC instead of -24d DEC )

how low can we go in the horizon with Pier14 in ALT ? 20degres ?

Laggon Nebula is way to low for me in lyon , and as i m located north of Lyon , i ve full light pollution from big city when looking south ....

Morning

The pier is set to image from 25º although the pier can go to as low as 15-20º if needed on occasion for special low stuff

However, there are caveats to this

1, You put a note with the order saying please lower the horizon limit to xxº as object very low
2, You understand from the outset that you are imaging through thicker atmosphere and sometimes the data may not always be super perfect and this is beyond our control


The other members of the group know this anyway but you are new

Steve

Hi,

That was my mistake with the declination. LOL! No wonder the Lagoon and Trifid were nowhere to be seen. I think I need a good holiday away somewhere. As Steve said we can go that low. This was only something I put in to ensure the pier was kept busy at the beginning. If you'd like to reenter it with the correct declination Florent then please would you do that. I'd quite likely mess up the RA the second time.

Cheers,
Ray

i will re sub this target , too low for my own setup

I have added another target. SH2-73, a reflection nebula in the border Hercules/Serpens, so riding high at the moment (job 1078). I have gone long on the L and much shorter on the RGB as the interesting parts of the nebula are essentially monochrome.

I ve replanne the image of M8 Laggon / M20 trifid on job 1079. this target is going to disseapear soon .

Mike , do you plan to submit again SH2-157, the bubble nébula ?

Thank you for doing that. I hope that Mike will do so since there are 3 well known nebula, Lobster Claw, Cave and as you mentioned the Bubble in that one frame/panel.
