IC 410 HaRGB

Posted By dan kowall
Nicely framed, surprisingly deep color for the exposure times (and use of Ha data), lots of detail on the tadpoles, and well processed, Jim.
My only quibble would be that the f/3.1 stuff has given you elongation along the left hand side?
You're braver than I for showing earlier versions! I use my 'delete' key a lot.

Horsehead and Flame

Posted By dan kowall
That is, indeed, most excellent, Vincent.
I'd show you my first RGB, but I destroyed all copies to avoid embarrassment and to avoid blackmail.
As you can see, the long RGB exposures provide rich color.
As Tom indicated, this area is a minefield for reflections and most imagers just leave them in.
Congratulations on a fine image.

Horsehead Season

Posted By dan kowall
Very pretty, Jim.
The full size image header promises a Horse Head AND a Flame, but I don't see a flame. Did it burn out?

Saturn with C11

That's one to be proud of, Ralph.

Ahhh! Crabs!!!!

Posted By dan kowall
Star colors are right on, you nailed the focus, not overly processed--you can't ask for much more in an image.
Way to go, Vincent.

Rosette in Ha - from Utah

Posted By dan kowall
Lots of detail there, Tyler. You did well for manual focusing; that's not an easy thing to do.
Nicely framed.
It looks a bit dark on my monitor. That could either be my monitor or the embedded profile.

M96 in Leo

Posted By dan kowall
Amazing.
I'm seeing detail here that I would expect to see in a 20" RC, not a widefield instrument, such as the dust lanes in the edge-on background galaxy. You also have a great start on the diaphanous 'haze' that surrounds this particular galaxy.
Way to go, Roland.

The Rosette in H-Alpha with tiny scope

I couldn't afford a bigger chip, so I did the next best thing and got a smaller scope.
Smart guy! There are plenty of Rosette-sized targets out there and, of course, guiding at that focal length is a breeze.
Your image is a little dark on my monitor, but the stars look sharp to the corners so it looks like you got focal reducer spacing correct.
You have a great start on a widefield gallery.

A rediculously simple question... *grin*

Posted By dan kowall
What Michael wrote about S/N is correct and is most applicable to nubulae.
Most people like to shoot globular clusters RGB unbinned with an exposure time as long as possible without saturating the stars.

Another try at the Rosette

Posted By dan kowall
Actually, your image looks pretty good for 60 second subs.
You're going to be dominated by read noise with 60 second exposures.
To take longer exposures to get a decent signal/noise ratio, you will need some sort of guiding.
With your setup, a DSI would be a nice entry level guider.
