Processing and Technique

Processing and Technique

A group dedicated to working through the toughest part of AP, processing.

To me, getting a pic finished for presentation is 1/3 capture and 2/3 processing (that includes calibrations and stacking). This group will work on the 2/3's part where pictures and techniques can be critiqued and discussed. By critique, I do not mean it to be a picture bashing fest, but on the other hand it does no good to say a pic looks great when there is say a severe light gradient in it. Keep in mind to say things in a way you wouldn't mind them being said to you, but on the other hand if you're defensive by nature maybe this is not the best place. I would venture to say most of us do not have anybody around who can look at an astro-pic and say "maybe too much saturation in the red". So here we have a bunch of experienced eyes who can take a fresh look at a pic and give an honest opinion. In doing so inevitably techniques will come up, which benefits everyone. Marc

I'll post a pic later. Unless somebody has got a pic they were trying to take after a bottle or two of champagne, that would be cool.

We can leave this open for tutorial links and people can add useful sites under replies. Maybe give a brief description first then the link to make it easier to reference.

H-alpha/Narrowband Pics

Shooting w/different line filters make for interesting pics on their own as well as a supplement to the RGB data.

That's pretty nice. Just downloaded a few mns ago and tried it out on a really green pic-like magic-gone. Thanks for the heads up, Marc

No problems with the HLVG plug-in. I use it everytime now. I don't have PS CS5 open at the moment, but I believe the plug-in has three settings. For my M42 I used the Strong setting for example. I've been doing it at the very end before I crop, if I crop, directly after a couple iterations of Carboni's make stars smaller.

Hey Jeff, thanks anyways, found the couple guys on the other site said they've had no problems. I've been leery of plug-ins since I down loaded a curves action (grants) for PSele8 I was using. The program would just shut down at will, no fun. But, while I got your ear, do you run this as normal work flow (any detriment(?)) or just when you think you need it . Thanks, Marc

Jeff, this is the second place I've heard of using HLVG. Did you find it to be a stable plug-in? Looks interesting. I took the liberty of posting these links in Tutorial Links. That way when the comments get buried after time, there will be an easy way to find these helpful links

Three things I wanted to post here. First, I'm in the early part of studying Warren Keller's tutorials:

http://www.ip4ap.com/

And Adam Block's tutorials:

http://www.caelumobservatory.com/video/dvd.shtml

I've spoken with Warren on the phone, he's at the top of the game when it comes to processing. Both these tutorial sets are just amazing.

Third, I read a post on here about 'getting rid of the green'. The absolute best thing I've found so far is Hasta La Vista Green. (HLVG). It's a Photoshop plug-in, and you basically just run it, simple as that, and voila, no more green in your shot. Wonderful tool. Anyways, just three things I wanted to contribute in this section.

Jeff

Ok, a new learning experience. I'm game.

Hey Trevor I figure somebody can break that into another group if they want, more of a hardware thing. My aim here was to have the link thing going for references and after that if people wanted to break off in different software directions say Maxim or Photoshop or etc. Kinda just see what evolves.

So this is all post imaging. Nothing prior to the closing of the shutter? I'm in!
