Still lost after 3 clicks

Post by EricD »

After my last post and the tips from Ivo I started reading the user manual and looked at a lot of video's. Tried processing several images over and over again, with the same result. Disapointing. I still can't get out 1 decent picture. What am I doing wrong, or do I have very bad data?
I stack in DSS with around 20 pics each for lights, darks, flat light and bias. I use a Canon 70D camera by Canon highest resolution and shoot in raw. This is typical data for me living in redzone lightpolluted area.
Let me show you some pictures of the first steps in processing data

I'm completely lost after using autodev. I don't know what I'm seeing here and what to do. Working with development doesn't give a much better result.
When I proces the image like the video M8 with modest data nothing looks like it and all signal is gone. When I use temp dev in between I see a picture with a lot of vignetting and noise, noise and more noise. At least that's what I think.

A processed picture in DSS and lightroom gives the following result

Is there someone who can proces my data and show me what you are doing, because I think it's a very interesting progam and I'm willing to pay for it but I first have to know what I'm doing and what the possibilities are whith my data.

Here is a link ( wetransfer) to a fits file of my data 230 Mb

I hope to see a much better picture as the povides jpeg file above

Hi Eric
I didnt see where you said how long your subs were. Also I usually shoot as many subs as I can, usually a minimum of 40 and sometimes as many as 70 or 80. I rarely if ever use as few as 20. I'm thinking more data would be useful. Tho we use different cameras,YMMV.
At any rate, my results processing your data is below along with the very basic workflow I used.

Hi Che,

First of all thanks for taking time for processing my data.
With this workflow I perhaps will understand a bit more whats happening when you change a setting.

The time for de subs is 167 seconds @ F5.6 280mm 3200 ISO and I used a CLS clip in filter.
There were twice as much subs but on a number of them there were tracks of planes and movement.

greetings EricD

Frames that have trailed are thrown away, but you can certainly use frames with planes or satellites. Just select kappa-sigma clipping as your stacking mode for lights in DSS.

I cant help you with your camera settings or exposure times as I use a OSC ccd camera so am not familiar with your type of camera. I know I've read much discussion on ISO settings on other forums.
Ecuadors comment " Frames that have trailed are thrown away, but you can certainly use frames with planes or satellites. Just select kappa-sigma clipping as your stacking mode for lights in DSS." is certainly true and may salvage many of your subs. Also satellite , airplane and meteor trails can also be removed effectively in the heal module.

Hi Eric,

Looking at the data and from what you posted here, it appears your flat frames are not applied correctly or not suitable - they appear to cause a light fall-off (across different channels), rather than correct for them.
It's also important to note that a CLS filter will skew your colors (it tends to remove yellow when everything else is otherwise reasonably well color balanced, typically leaving you with either orange or blue stars).

Che definitely did a nice job with the data as-is and you'll notice in particular that he expertly used the Wipe module with a heavier aggressiveness towards the corners (due to the falling off gradient).

You got the nebulosity and associated structural detail in that area showing though, which is a nice start!
