A slice of sun

Posted By Ron Wodaski
Awesome! I can see some faculae near the center of the disk - usually I only see stuff like that near the edges. Very crisp.

RGB layers / Photoshop Elements ?

Posted By Ron Wodaski
To move a color layer in Photoshop 5.5 or later (may also work with Elements and earlier versions of Photoshop, but not tested there):

* Open the Channels palette
* Select the channel you want to move (e.g., Green) by clicking on the channel name
* To see the other color channels while you do this adjustment, click in the "eyeball box" at the left of the RGB channel. You now see all channels, but only the selected channel will be affected.
* Select All (Ctrl + A) so you can move the channel's layer.
* Hold down the Ctrl key and use the arrow key to move the channel.

Repeat for any other channel that requires alignment.

Does anyone use Tpoint?

Posted By Ron Wodaski
By any chance are you imaging with an SCT that does not have its mirror locked down?

Little Ghost with color added

Posted By Ron Wodaski
I should have mentioned: this is a very dusty area, and nearly all of the stars are noticeably reddened by the dust. There are a few bright foreground stars that are somehwat bluish. The bright star just above center is quiet red, indicating that the colors are balanced even though the appear heavily skewed toward red.

Albiero

Posted By Ron Wodaski
Thos are internal reflections from stuff inside the camera. The stars are very bright, so reflections are not unexpected.

which would you rather have?

Posted By Ron Wodaski
The 12" Dob will have not only more aperture (aperture always wins, even in light-polluted skies), but it will have a faster focal ratio, which will make extended objects brighter and easier to see.

The main apeal of the SCT would be for planetary observing if it has a longer focal length, but in the end the larger aperture of the Dob plus a Barlow will get you some very fine planetary viewing as well.

Especially since you aren't after goto, a larger aperture will be the ticket - especially if you get one with a good-quality mirror.
