Hello from Austria!

 

I have reworked the data that was made during this year's trip to America.

 

Location: Bryce Canyon (Bortle 1)

 

rho ophiuchi app

 

 

Full quality: https://www.astrobin.com/kdaqyt/?nc=user

 

This time I used APP for stacking and calibrating the pics and Starnet++ (new in the workflow) to edit the nebulae and the stars separately. The final tweaks were made in Photoshop.

 

Thanks to @jw_duijndamhetnet-nl and @kijja for the technical help 🙂

 

I'm looking forward to your feedback!

Tip for others; opening the image above in a new tab also gives a better resolution to view.

I think the amount of data is amazing, clearly those skies work. 🙂 If I may and hit on a few points? I notice that the nebula has some spotty pattern, could it be a bit over-stretched? This also seems to be the case looking at the background around the stars.

I know what you mean Vincent. When I remove the stars from the image with Starnet ++ you get a very noisy result. Maybe you have to smooth the starless picture ...!?

Do you have any idea how to solve the problem?

I would be interested anyway what a PRO could get out of this stack 🙂

I'm no pro, but would love to give it a go. I do have extremely bad Internet where I am now, so downloading will take a while. Personally I'm a fan of not too many tricks with software, the data is what it is and if you really need to use other things to kind of "boost" a result, my take would be to just take more data. 😉 But that's personal, I'd like to see what can be done still and thanks for offering to do that.

I'm very curious what you make of my data 🙂 I understand your approach that is also good, because otherwise all pictures would look the same!

Thank you Gernot! I'll just start the download and see you back in a year. 😉 It's slow, but we'll see.

ps. Would it also be possible to get a masterdark, flat and bias? And then a subset of the raw light frames? With only the final integration I can't play as much.

@skanker

Just have time to look at your beautiful image, congratulation! I like the way Vincent @Vincent-mod's approach; he always see some points that you can improve your images. I eager to see a newer version of this image.

Clear skies,

Thank you @kijja my comments are never meant to be negative, I just like to see if I can help people improve. If they are happy though, I'm totally fine with that too. 😉

Here is my new version:

 

Antares APP

 

 

@vincent-mod I think now it looks more "natural" and the noisy pattern is not so pronounced.

 

@all I ask for your critical feedback 🙂

Yes, excellent! I actually tried myself, but gave up as I couldn't "quickly" get anywhere near your result. I don't use photoshop, so I guess there are some nice tricks done in there. 🙂

@skanker

Hello, 

I am about to comment on the brightness of small stars in the second image. When I scrolled to see your final image, and it is what I meant to comment. Very nice image, I wish I could have one like this!

All the bests,

Kijja
