View Full Version here: : Have a go at processing this
25-03-2012, 04:57 PM
I did a quick run with the hyperstar last night and a 45 second unguided exposure of Orion at F2 on a C9.25 SCT.
I just thought I'd post the file here if anyone wanted to have a go at processing. It has trailing stars and other issues which makes it a good one to learn on.
So anyone thinking of getting into AP, have a go at this, and see if you can polish a turd.

Pete, I couldn't get the link to work.

Sounds like a candidate for "StarTools". Right click Save Link As

I just tested it, yes right click on the link and choose 'Save Link As' if using firefox, or 'Download Linked File' in Safari.

Let me know if the link doesn't work.

Got it into a TIFF file, opened it in CS5. The core is blown out but a lot of outer detail there.

Peter, after download I get a .fit file which Windows can't open.

I'm not all that experienced in photoshop yet, but here's my quick attempt.

Nice Paula. I like the 3D effect in your processing of Peter's data. This is the sort of image that I would like to end up with myself.

Thanks Stu, as i said my processing skills aren't great yet but im hoping to get something like that too. Its a learning curve but it's all part of the fun!

I just realised I didn't even say what the image was of, or post a reference image!
This was what I got from it after a very quick stretch in Nebulosity. I'll be interested to see what anyone else makes of it.

Heres my quick 5 min effort before I go to work

Peter you might want to consider posting a link to a TIF rather than a FIT.
Most people in the beginners astrophotography world wouldn't know what a FIT it or how to convert it.

Good point Mike, though I guess the learning starts right here then with working out how to open/convert that file :D
Some FITS resources are here:
Alternatively, here is a link to the file converted to a 16bit .tiff
The file poses some fun challenges, there are some troublesome gradients, a bit of trailing and some colour issues that all need work.

Quick attempt in StarTools v1.2beta
Odd purple colour cast in there.
