Hello all,

 

There have been a lot of new faces popping up here in B&II, and I wanted to go back through and share out links to all of the data I have provided in the past for people to process. If you are new, this is a great opportunity to play with some good data, and if you are not new, this is a great way to hone those skills! Regardless, I know a lot of people across the US are facing poor weather, so what better time to reshare all of this wonderful data? grin.gif

 

These are all Narrowband integrations, but do not let that scare you from trying! Narrowband data, if anything, allows for a vast realm of artistic influence and endless opportunities to blend to your hearts content. flowerred.gif

 

Without further ado...

 

Pelican Nebula, HA/OIII/SII

Crescent Nebula, HA/OIII

https://1drv.ms/f/s!...jiZ4oTE9CQ8AKog

 

North America Nebula, HA/OIII/SII:

https://1drv.ms/f/s!...4P1909X7V8BBuSA

 

Elephant Trunk Nebula, HA/OIII (NOTE: Elephant Trunk data is also lights and calibration frames thus you will need to process from the ground up)

https://1drv.ms/f/s!...-TbvJtm9_40MLAg

 

Bubble Nebula, HA/OIII (NOTE: Full integration data provided, you will have to roll your own masters from ground zero!!)

https://1drv.ms/f/s!...vDCeArjD41sSLhg

 

PacMan Nebula, HA/OIII

https://1drv.ms/f/s!...U3ErgReajDalWDQ

 

PacMan Nebula Revisted, HA, OIII, SII (Very high quality data, best data I have taken yet)

https://1drv.ms/f/s!...aCYbPyb101CeFTQ

 

 

The vast majority of this data was taken with a Takahashi FSQ106ED and a QSI690WSG-8 camera. The PacMan Nebula data was taken with a Takahashi TOA130 and the QSI690 camera, and to this day remains the best set of data I have ever managed to get. I believe the full Bubble set of data was taken with the TOA130 as well. All integrations were done on a Astro-Physics 1100 GTO CP4 mount, and use Astrodon Narrowband filters. Processing of masters was done in PixInsight. 

 

Let me know if you have any questions. All I ask is that if you publish your processing of this data somewhere, just please give me credit for acquisition. Otherwise, have fun, learn a thing or two, and to steal the advice from Goofi, let the data guide you to what you want to make of it in the end.

 

Thanks,

Bill

Wow, thanks!

No problem. If any of the links dont work just let me know and I can fix them. :) I tested them though so I think they are good to go. 

 

If you have any questions about the data, processing it, etc... just add them to this thread and I am sure someone will be willing to help. waytogo.gif

Here's my rough attempt at the "PacMan Nebula Revisited" data:

 

PacManNebula.jpg

 

Processed in PixInsight.  I didn't do much for this process at all - I used a SHO palette, tried to enhance the dark bits of the nebula and didn't stress over the stars or the general background dark level too much. 

 

I thought it might be worthwhile for those that are having a go at this data, to post some results here too.

Bill,

 

Thanks for posting this.  I have now processed a total of 3 sets of other people's NB data.  This will give me more practices until I can get my own data (getting slow start on LRGB at the moment).

No problem. Good data to play with here, and one of them is a full set of lights with the appropriate calibration files.

Putting on my Moderator hat ....

 

I'll get this thread linked into the "Deserving Threads but not Stickies" later today.

I might - might - leave it pinned at the top for a month or so to keep its awareness high.

 

Bill .. thanks for starting this one, and if others have data they're willing to share, post away.

But please, if you post a link to data, keep the data available. Dead links are annoying.  wink.gif

Good point about the dead links. The link I shared that was dead had an expiration date on it that I missed when creating the post. I removed the expiration date and made sure the rest were read only and did not expire. All good now. grin.gif

Good looking go at the data. There is a ton of detail you can still pull out of this one for sure. 

 

Here was my end point on the data: https://www.astrobin.../full/315698/0/

 

I did a SHO/HOO mix of the two sets of data I provided for PacMan. A bit advanced, but it should at least give you some idea of how much detail is hidden in there to find!

Bill, thanks for sharing these. I had to give the bubble a try since it included pre-processing as well as post-processing. I did two versions in pixelmath and blended the two images together - R=Ha + G=OIII, and R=Ha + G=OIII + B= Ha*.25+OIII*.25

You're welcome. I also need to go back and reprocess some of this data at some point. Once things slow down. By then, I will probably have new data though. lol.gif

WOW, i didn't download anything yet but i am going too, i like these kind of topics, i am new and any data will definitely help me no doubt, and in another thread i said it is not only about processing but even the light exposure itself, i would like to learn more about how they should be before i do processing, it is nothing worse than wasting time out for exposures to find out that they are bad enough that even processing isn't worthy.

 

Thank you very very much for this! waytogo.gif

The Bubble Nebula data has all of the individual subs included along with the calibration masters to process them all. waytogo.gif

Be sure to post up what you manage to make of the data. 

 

Also -- others are welcome to share data sets on this thread as well!

Finally i downloaded all files, thank you very much again for that, i don't know how to use PI at all yet, but it is good time now to learn it before i can get a new scope and then having data by myself.

You are welcome, Tareq. The data is from those Takahashi scopes you like as well. grin.gif

 

Folks can use PI to process the data, Photoshop, or even Astro Pixel Processor. The Bubble Nebula dataset would be great to use with that since you have to process the data yourself. All I provided was the master flats, bias, and dark.

I have to resist the addiction and the bug of $$$$$, i am already in bad situations, i want to have something expensive really, but that may have to wait a bit longer, and i will try to use one of good reasonable price scope for a while, after all i don't think the difference must be a huge one, i am using NB with LRGB and under LP so it won't help much with Takahashi anyway, and after all i know where to buy a Tak later if i can wink.gif

 

I d have PI and Photoshop, but many posts around the net showing that PI is a powerful app in astrophotography, Photoshop too, and APP, but PI is like a standard or a RR of apps in astrophotography, so i better focus on it at the best and not getting lost trying to learn many apps at once or even swapping between them much, Photoshop enhancing and retouching won't have much problem even i am not good at it because i used it for years in my photography.

I think APP is a great tool. You can produce good enough data, with very little effort. However, I think the precision of PI and what you learn going through its massive learning curve makes you a better astrophotographer in the end. With that said, I hear that PI's mosaic capabilities are far too difficult on people, and that APP shines when it comes to mosaics. So at this point I own a permanent license for both, as I see value on both ends.
