Antares and Rho Ophiuchi from Astrofest

This is 15 x 5 min shots with 5 darks through my SW ED80 - guided

Stacked in Nebulosity and processed in PS4

Any suggestions on how I can increase the Central Yellow area?



Thanks Geoff

Nice one Geoff.

My first suggestion would be to restack the images using a median combine. That should get rid of the satellite that screamed through your image.

To increase the intensity of the yellow you can do a number of things. As a first suggestion try sliding the central gamma slider in levels in the red, green and blue channels to move your histogram for each channel further to the right and spread it out a bit more. Then try adjusting curves using the red and green channel. Not too much and use a lower end adjustment point. The colour should be starting to come out by now. Then try adjusting your midtone colour balance and then adjust the shadow colour balance to bring the background into balance.

It's a very rough explanation and process. I've done it on your uploaded jpeg to give you an idea. Its severly clipped probably because it's an 8bit image, but check the histogram to see the spread.

Good luck.

Paul,

Thanks for the suggestion I'll give it a try

Nice image Geoff.

hey its just like Paul's image - yep a repro (must thank Mike Sidonio for that word.......) would be good

Nice dust cloud Geoff, again the only real improvement comes from more exposure. More data to work with allows much wider stretch ability and better detail overall.

I always wondered how this field would look through 80mm of aperture. Thanks to you and Paul, I now have an idea and can attack it next year.
