Discussion Overview

The discussion revolves around the process of improving astrophotography images, specifically focusing on the Eta Carina nebula. Participants share their experiences with image editing software, techniques for stacking images, and the challenges of achieving high-quality results in astrophotography.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant describes their workflow using Photoshop and a specific set of actions for astro-imaging, detailing the steps taken to process their Eta Carina image.
  • Another participant expresses admiration for the improved image and acknowledges the steep learning curve associated with mastering Photoshop.
  • There is a discussion about the differences in exposure times and techniques used by amateur astrophotographers compared to those featured in Astronomy Picture of the Day (APOD).
  • One participant mentions plans to upgrade their tracking system to allow for longer exposures, which they believe will enhance their imaging results significantly.

Areas of Agreement / Disagreement

Participants generally agree on the challenges of astrophotography and the importance of processing techniques, but there is no consensus on specific methods or outcomes, as each participant shares their individual experiences and aspirations.

Contextual Notes

Limitations include the subjective nature of image quality and processing techniques, as well as the varying levels of experience among participants, which may influence their perspectives on the effectiveness of different methods.

Who May Find This Useful

Astronomy enthusiasts, amateur astrophotographers, and individuals interested in image processing techniques may find this discussion relevant.

Really been spending time in Photoshop practicing astro image editing ... purchased a set of astro-imaging actions called Astronomy Tools Actions Set
http://www.prodigitalsoftware.com/Astronomy_Tools_For_Full_… ...
this is an actions addition for Photoshop

I have been following a video ... http://www.myastronomyjournal.com/DSL…/C002-M31-Walkthrough/
where this guy makes use of many of the action processes with the end result that I have been able to do a new and improved rendition of my Eta Carina image set. 8 x 30sec images stacked in DSS saved as a 16bit TIFF then imported into PS for processing
The 8 images that I used were ones I took back in Feb. of this year

8 x 30sec exposures, 400mm, f5.6, ISO3200 on my Canon 5D Mk3

2016-02 Eta Carina 8x30sec PSeditedsm.jpg
Firstly the 8 RAW images plus 4 x "dark" images from the camera are stacked in DSS ( Deep Sky Stacker), saved as a 16bit TIFF and then loaded into Photoshop for processing
See this thread for recent discussions on using DSS

Thanks mate :wink:

it's a steep learning curve, Photoshop has so many featured and I'm really only scratching the surface
My processing skills are slowly improving

You're doing quite well so far. I was looking at an APOD photo the other day wondering how amateurs manage to get such great colors.

thank you

lots and lots if fine processing ... there's many very talented photoshop users out there :wink:
I had 8 x 30 sec images = 4 minutes of total exposure time. That APOD image probably has many more consisting of longer individual exposures
Am working on getting my new tracking system up and running so that I can start doing around 5 minute exposures instead of 30 sec, then stacking a whole bunch of 5 minute exposures.
Then you will see a whole new level to my imaging results :smile:
