Re: WANTED - DSLR image set

Hi Rowland,

I think I have a full set for this: http://www.astrobin.com/182338/

I don't think I added the bias images in my final image but I do have some. Camera is a Canon CDS-600.

Let me know if they are what you are after I will upload them.

Rosette Nebula

Here is Rosette Nebula done a few weeks ago. Interested in feedback on my processing. Also, what is the SimLum that posters are talking about? Is there a link to it?

Re: Flat with modded DSLR

Rowland, I read somewhere that for DSLR bias frames are already added to every image, so that would mean that lights, darks (as you said) and flats already have bias images added to them, so there is no need to use them separately in stacking. Can you explain why you use a master bias with the flats...

Not sure why t...
