M33 from Astrofest * COLOR BALANCED*

multiweb (Marc) · #1 21-08-2015, 09:16 PM

Here's M33 the Triangulum Galaxy from Astrofest. Good elevation for it. I did 2 nights on it so nearly 3.5h over two nights in 5min subs.

FSQ106N/QHY8 on G11.
I have a full field 1:1 here [6MB - 2982x1930]
A 1:1 crop here also: [2.2MB - 1832x1145]

Did this one in CCD Stack and PS5.
Feedback welcome.

PS: updated all the files with color balanced (hopefully) correct ones this time.

Beautiful; with that delicate colour it looks like a silver brooch.

Marc, hats off to that image. Great detail and excellent processing.
Have to put that one in my todo list for next year.
Good to catch you at Astrofest

Nice one Marc. Nice detail, perhaps a little under-saturated for my taste but that's a very personal thing. Great image.

Great field Marc. So much to take in.

Beautiful work Marc. I've got quite a bit on this one too with the ED but have only managed to get to lum processing stage so far. Have had lots of fun swimming around in your large size 5mb frame!

Yes - was great to meet you in person after years of enjoying your many constructive posts. Reminds me how very helpful it is to be learning all the time from the many expert IIS contributors.

RobF (Rob) · #9 22-08-2015, 12:27 AM

Actually that's quite a big FOV Marc. Did you use a reducer with the QHY9/FSQ? I didn't know there was one available?

multiweb (Marc) · #10 22-08-2015, 07:44 AM

Thanks guys. Too kind. Looking at it this morning it looked a lot better last night. I managed to do square stars. Will have to check my debayering. Not having much luck with my colors either. That's probably why I don't do galaxies.

Thanks. I reckon I'll revisit the color when I figure out what I'm doing wrong.

Thanks Allan.

That should nicely fit you fov. Good to catch up with you at astrofest too and thanks for the help with the tarp during the "sun shower".

Thanks Rex. You're absolutely right. Time for a repro this week end.

Thanks Rob. Great to finally meet you too. It was a QHY8. My bad. It's slightly wider than the QHY9 and has much bigger pixels unfortunately.

Perfect subject for the optical train, and perfect subject for a trip to Qld. Huge amount of detail in the galaxy. Stars look fine to me. No coma, sharply in focus. Very deep and clean for only 3.5 hours. Reckon you'll have no trouble tweaking the colour. It's all there. Congratulations.

gregbradley · #12 22-08-2015, 09:46 AM

Great shot Marc. But where's the colour? Its great luminance and detail but a bit lke a Crème Brulee without the topping!

Slawomir (Suavi) · #13 22-08-2015, 10:05 AM

Echoing others - your photograph allows to apreciate this galaxy in fine detail

Thanks Mike. Will have a play this weekend and update the shot.

Too right. Bit on the gooey side and not crunchy enough. Need to look for a good galaxy processing tut online. It clearly is different from diffuse neb processing.

Thanks mate. Happy with the level of details for that FL but that's about it.

Somnium (Aidan) · #15 22-08-2015, 12:22 PM

wow, great effort Marc!

Thanks for the encouragements mate.

Going to give the galaxies a rest for now and process the veil nebula. I can deal better with diffuse nebs at least.

Hi Marc,
Nice data.
I hope you don't mind?
I had a bit of play with your picture in Photoshop
& got some more colour & contrast out of it.
I used LAB mode & curves & many blurred masks.
What do you think?

cheers
Allan

ozstronomer (Geoff) · #18 22-08-2015, 07:08 PM

Great Image Marc, love that FOV and nicely processed

Nice to catch up at Astrofest

Cheers Geoff

Camelopardalis (Dunk) · #19 22-08-2015, 07:28 PM

Good catch Marc

lots of detail in there and wonderful image scale too!

Looks like it could benefit from a slight tonal shift more towards the blue though, at least on my monitor it looks a touch towards green

Thanks mate. Yeah my color balance is a bit out. I'm planning on doing a repro.
