SPSP Widefield Crux

1ponders,
I was on sRGB, that setting is now changed to adobe, I guess that will still be helpful with the jpg (I don't use these for stacking)

H,
If i was to find out the temperature when I took these shots and redo the darks would this help? or am I pushing the expletive up hill?

Cheers,

Trent

Trent and Julie,

Personal opinion is no, as DSLR sensor performance varies too much.

However, give it a go and see how it turns out. Whilst you're at it, take some flats and flat darks.

If your lens and sensor were fairly clean and you can get your focal length and focus back to where you had it at the time of image capture, you may able to sort out the vignetting.

Take your flats at ISO-100. Point your camera and lens to your notebook screen, load Photoshop up and create a new document with a white background. Hit 'F' a couple of times to go into full screen mode and hit Ctrl++ a couple of times so the document fills the screen. There's your flat field! Take 15, or, so (you want an odd number of frames for the median combine algorithm to work effectively). The same rules also applies to darks and flat darks. Take a few test flats and check the histogram. You want the curve to peak somewhere between 1/3rd to halfway across the X-axis.

Hope this helps.

Hey Guys,

This is our final SPSP Crux, Admittedly more could of been done initial stages, but We think that this is as good as our collected data will allow us.

Same images, different stacking method in DSS (used averaged stacking and allowed DSS to do the colour balancing)

We also calibrated our Laptop screen with a device named huey, what a huge difference it has made! We recommend them to anyone

Thank's for all the comments thus far, We found them constructive, and they will be all taken heed of on our next imaging run,
Cheers,

Trent and Julie

Noice. . much better size for viewing as well. It shows quite red overall, but that certainly doesn't detract from a very nice image
