It's very kind of Bert to make his data available.

Thanks Allan, me too, colors are explosive

and thanks again to Bert for his kindness

Just link to this thread Elio. I do not bother with a web site.

I thought very carefully about all aspects when putting together this dream system.

In all of science there is only one dogma. Signal to noise is the only criteria to judge the quality of ANY data.

I went for the far superior S/N and well depth of the PL16803.

The RH200 has far better resolution than the 3.08" per pixel of the PL16803.

This can be recovered with dithering and upsizing before stacking. PI has just released a drizzle module that does the same thing but is more mathematically robust or correct.


For faint nebulae especially in NB better resolution is meaningless if the signal is below the total noise of the system.


If you can see faint dust with texture and colour variation and resolved to the core globular clusters in the same image then the signal to noise ratio is very high. True depiction of the full dynamic range of the target object is then also achieved.

Ok!

Sure, you are right, but I can't spend 10k euros for a ccd, I'd settle for the RH200

Yes - I especially like the yellow.
