Another star color

Post by gardenfish » Sun Jan 22, 2017 12:32 pm

This was HSO from last night. It shows the r-g-b separated better. It looks the same in PS or PI. Scaling? rotation? ......? The colors are in line in center and off on right and differently on top left. If I try without the ff would it change? Is it the camera angle?

See if you can post a link to your stacked images (FITS or XSIF). To me, it looks like things aren't aligned. But, I may come up with the same results.

There are three files:
Autosave.tif
Autosave001.tif
Autosave002.tif

Can you ID each file for me?

Hi Rick,

After looking at your frames, there are some problems that are contributing to the halos.

Ha = Looks Good.
OIII = Stacking Problems.
SII = Out of Focus.

This doesn't mean you can't resolve these problems, but, you'd have to work on these problems before layering them together. The star sizes need to match. If your SII has balloon stars and your Ha has nice sharp stars, then you'll see what you've got now.

The OIII, not sure if this was tracking problem, or if it was stacking problem. Something did stack correctly and the stars "stuttered".

Also, some times you need to just throw it away and learn moving forward. If seen similar results on my images and you can punch it around until looks ok. But you got to remember, GIGO. It looks like you have GI and your results are showing GO.

Not trying to be brutal...just being honest. I hope this helps.

Doug

Now here's something you can try...This has worked for me in the past. "Tone Mapping" Check out this:
viewtopic.php?f=14&t=821" onclick="window.open(this.href);return false;

Basically what you do remove the stars and build the nebula... Very effective.

Thanks for your help. No such thing as too brutal. If you dont tell me how can I learn. I will check out the tone mapping and see what happens.

If you try tone mapping, you'll recover the Nebula Signal, but, your stars will be white. Not a bad deal. I've used Tone Mapping to Help salvage images of mine.
