Cocoon Nebula

[MarkS]

Another work in progress.  This one from last night.

21 x 5min using modified EOS 350D on C11 at F6.3
I'll process it better when I get home.

This has been 3x3 binned and then cropped.

Lovely image Mark, I really like all the grey cloudy nebulosity that's showing up and the colour looks natural (if one can use that term ! with astrophotography!)

[JohnP]

yep fantastic again Mark... When you coming home you are seriously depressing me wth all these images you keep posting...!!!!!

That's lovely Mark, again, one of those objects I just can't get anything more than a smudge out of here

[MarkS]

I drive home Sunday

One question about binning DSLR images, I've tried the binning in IRIS and that tends to blow out the image quite a bit, however when I do it in MaxDSLR, it doesn't but I don't really see any improvement over bicubic resizing in photoshop, am I doing anything wrong?

[MarkS]

Daniel,

In IRIS, to prevent blowout, do a "mult 0.25" before 2x2 binning or "mult 0.11" before 3x3 binning.

very nice i love the blue bits

Here is the re-processed version.

32 x 5min using modified Canon EOS350D on Celestron C11 and F6.3 reducer.
2x2 binned and cropped.

Great image, Mark. The modified camera's certainly do a good job!

Really superb image Mark. Some of the best detail in the Cocoon i've seen.

[MarkS]

Thanks for you comments. 

One thing that also helped was that the seeing was quite reasonable that night.  One annoying thing is that I lost approx 8 subs because of dewing:  I dozed off and then awoke to find dew on the telescope corrector plate

[Mike]

You want a dew alarm you do.

Fantasic image Mark, especially on such a "git" of an object, really nice processing too, love the patches of dark nebula around the outside.
